ZD Net : iPhone 15 Pro overheating resolved: Thermal photos before and after iOS

iPhone 15 Pro overheating resolved: Thermal photos before and after iOS 17.0.3
ZDNET conducted thermal imaging tests on iPhone 15 Pro after Apple's iOS 17.0.3 update and has concluded the overheating issue with fast-charging appears to be resolved.

Apple rolled out its iOS 17.0.3 update on Wednesday with a release note that it "addresses an issue that may cause iPhone to run warmer than expected." ZDNET has tested this update and using a thermal camera has concluded that it has indeed resulted in the iPhone 15 Pro and Pro Max running cooler when fast-charging.

As widely reported since the arrival of iPhone 15 Pro on September 22, the iPhone 15 Pro and iPhone 15 Pro Max could get very warm when fast-charging or when using third-party apps such as Instagram, Uber, or Asphalt 9 that appeared to exacerbate a flaw in the iOS 17 software. Apple insisted that the overheating issue was related to a software bug and was not related to the new hardware or design in the iPhone 15 Pro models, which introduced a new titanium frame with an aluminum substructure to replace the stainless steel frame from the past several pro models.

In my testing with the iPhone 15 Pro and Pro Max, I experienced two overheating issues. The first and most major one was the iPhone 15 Pro Max getting very hot to the touch when fast-charging it with Apple's USB-C cable connected to a 35W charging brick. I was able to replicate this experience in another location using the same cable and charger. I used a thermal camera to measure the heat and found that the iPhone 15 Pro Max got as hot as 107.1 degrees Fahrenheit.

This was much hotter than other iPhone and Android phones, which typically maxed out at 85 to 95 degrees when fast-charging in my tests. The hottest any other phone got when testing in the same conditions was the Samsung Galaxy Fold 5, which got up to 98.7 degrees Fahrenheit.

The other overheating issue that I noted in my iPhone 15 Pro review appeared when jumping between the third-party camera app Halide and Apple's stock camera app while I was shooting a lot of photos outside on an 82-degree day. When I would swap back to the Apple camera app, it would very briefly display a message saying "iPhone needs to cool down" for 1-2 seconds before I could start using it again. Halide has also issued an update to its app that appears to have resolved that issue.

TechCrunch : OpenAI said to be considering developing its own AI chips

OpenAI said to be considering developing its own AI chips

OpenAI, one of the best-funded AI startups in business, is exploring making its own AI chips.

Discussions of AI chip strategies within the company have been ongoing since at least last year, according to Reuters, as the shortage of chips to train AI models worsens. OpenAI is reportedly considering a number of strategies to advance its chip ambitions, including acquiring an AI chip manufacturer or mounting an effort to design chips internally.

OpenAI CEO Sam Altman has made the acquisition of more AI chips a top priority for the company, Reuters reports.

Currently, OpenAI, like most of its competitors, relies on GPU-based hardware to develop models such as ChatGPT, GPT-4 and DALL-E 3. GPUs’ ability to perform many computations in parallel make them well-suited to training today’s most capable AI.

But the generative AI boom — a windfall for GPU makers like Nvidia — has massively strained the GPU supply chain. Microsoft is facing a shortage of the server hardware needed to run AI so severe that it might lead to service disruptions, the company warned in a summer earnings report. And Nvidia’s best-performing AI chips are reportedly sold out until 2024.

GPUs are also essential for running and serving OpenAI’s models; the company relies on clusters of GPUs in the cloud to perform customers’ workloads. But they come at a sky-high cost.

An analysis from Bernstein analyst Stacy Rasgon found that if ChatGPT queries grew to a tenth the scale of Google Search, it’d require roughly $48.1 billion worth of GPUs initially and about $16 billion worth of chips a year to keep operational.

OpenAI wouldn’t be the first to pursue creating its own AI chips.

Google has a processor, the TPU (short for “tensor processing unit”), to train large generative AI systems like PaLM-2 and Imagen. Amazon offers proprietary chips to AWS customers both for training (Trainium) and inferencing (Inferentia). And Microsoft, reportedly, is working with AMD to develop an in-house AI chip called Athena, which OpenAI is said to be testing.

Certainly, OpenAI is in a strong position to invest heavily in R&D. The company, which has raised more than $11 billion in venture capital, is nearing $1 billion in annual revenue. And it’s considering a share sale that could see its secondary-market valuation soar to $90 billion, according to a recent Wall Street Journal report.

But hardware is an unforgiving business — particularly AI chips.

Last year, AI chipmaker Graphcore, which allegedly had its valuation slashed by $1 billion after a deal with Microsoft fell through, said that it was planning to job cuts due to the “extremely challenging” macroeconomic environment. (The situation grew more dire over the past few months as Graphcore reported falling revenue and increased losses.) Meanwhile, Habana Labs, the Intel-owned AI chip company, laid off an estimated 10% of its workforce. And Meta’s custom AI chip efforts have been beset with issues, leading the company to scrap some its experimental hardware.

Even if OpenAI commits to bringing a custom chip to market, such an effort could take years and cost hundreds of millions of dollars annually. It remains to be seen if the startup’s investors, one of which is Microsoft, have the appetite for such a risky bet.

WSJ : Saudi Arabia Willing to Raise Oil Output to Help Secure Israel Deal

Saudi Arabia Willing to Raise Oil Output to Help Secure Israel Deal
Riyadh signaled to White House it would act if crude prices are too high to win goodwill in Congress

DUBAI—Saudi Arabia has told the White House it would be willing to boost oil production early next year if crude prices are high—a move aimed at winning goodwill in Congress for a deal in which the kingdom would recognize Israel and in return get a defense pact with Washington, Saudi and U.S. officials said.

That understanding is part of an effort to seal a three-way agreement that would also likely include U.S. nuclear assistance and represents a notable shift by Riyadh, which a year ago rebuffed a Biden administration request to help lower oil prices and fight inflation, severely straining relations.

Still, Saudi negotiators emphasized that market conditions would guide any action on production and officials familiar with the talks said the discussions didn’t represent a long-term agreement to cut prices.

Spokespeople for the White House National Security Council and the Saudi government didn’t respond to requests for comment.

Talks on a deal have centered on Saudi recognition of Israel—a move that could revamp the geopolitics of the Middle East—in return for U.S. weapons sales, security guarantees and help building a civilian nuclear program. An agreement would be a diplomatic coup for President Biden as he faces a tough re-election battle.

Saudi Arabia hasn’t recognized Israel since its founding in 1948, and a deal establishing diplomatic relations would expand Israel’s ties to the Arab world, potentially constrain Iran’s military ambitions and curb China’s efforts to supplant American influence in the region.

Two top White House officials, Brett McGurk and Amos Hochstein, flew late last month to Saudi Arabia, where they emphasized that soaring petroleum prices would make it harder to win support in Washington, the officials said.

The White House may need congressional support for a deal. Negotiators are now discussing a new defense pact with the kingdom that could require Senate approval as well as U.S. support for Saudi efforts to create a civilian nuclear program, and billions of dollars in weapons sales.

The trip by McGurk and Hochstein came amid a climb in oil prices, with the global benchmark, Brent crude, rising 25% this quarter and trading as high as $95 a barrel. It has pulled back in recent days, trading above $84 a barrel Friday.

The Saudis have been pressing for higher prices as they pour tens of billions of dollars into megaprojects aimed at transforming the kingdom’s economy. Public acknowledgment that the Saudis could act to cool the oil market next year might have the effect of capping oil prices under $100 a barrel, a historically high level that has in the past fueled inflation and led to calls in Washington for action.

As the world’s largest oil exporter, Saudi Arabia has a unique capacity to influence crude prices, with the ability to restrict the world’s oil supply or flood it. The kingdom has used that power to calm markets during periods of global turmoil, but under Crown Prince Mohammed bin Salman, the nation’s oil policy has become known as “Saudi First,” as the kingdom looks to fund its economic diversification.

Any move by the Saudis to raise output would be complicated by its energy-production alliance with Russia, itself one of the world’s largest oil producers. The kingdom has moved in lockstep with Moscow, which has tried to keep oil prices high by restricting production, keeping oil money flowing into its coffers to fund its war in Ukraine.

The Saudis and Russians lead an oil-producing group known as OPEC+, which is set to meet at the end of November to decide output levels. The 23-member group cut oil production by two million barrels a day a year ago in a move that infuriated the Biden administration, and Saudi Arabia and Russia have cut even more on their own since then—actions that are due to expire by the end of 2023.

The Biden administration hopes to broker a Saudi-Israel agreement in the next six months. The three sides have broadly agreed on the contours of the deal and are starting to hash out thorny details.

McGurk, the White House’s top Middle East official, and Hochstein, Biden’s senior adviser for energy and infrastructure, have repeatedly pressed Saudi Arabia to make moves to repair its image in Washington, where Congress could play a key role in making or breaking a diplomatic deal with Israel.

Lawmakers from both parties have expressed reservations about offering such support to Saudi Arabia or giving a diplomatic boost to the 38-year-old crown prince, who, while moving to revamp the economy and ease conservative social mores, has also sought to silence dissenters.

U.S. intelligence officials said Mohammed sent a special team to Istanbul, where its members killed Jamal Khashoggi, a dissident Saudi journalist, U.S. resident and Washington Post columnist who wrote pieces critical of the kingdom’s young ruler.

Mohammed characterized the Saudi hit team as a rogue unit and has said that he has moved to prevent any similar killings from happening under his watch.

Biden himself vowed when he took office to treat the kingdom as a pariah because of its record on human rights. But Biden began to shift course last year when he flew to the kingdom and famously gave Mohammed a fist bump that signaled a new cooperative relationship between their two countries.

Since Russia’s invasion of Ukraine sent energy prices soaring, the Biden administration has focused more attention on oil-rich Middle East petrostates whose problems it tried to de-emphasize early in the president’s term. There has been progress on several fronts.

Since Biden took office, Saudi Arabia has moved to extricate itself from a long-running war in Yemen. Saudi Arabia halted airstrikes and agreed to a cease-fire that has brought significant calm to Yemen for the past year. The U.S. and United Nations have been working to broker a long-term truce and to accelerate peace talks meant to bring the war to a close.

The Biden administration has been encouraged by Saudi Arabia’s recent outreach to Israel, including the kingdom’s rare decisions to allow two Israeli ministers to visit the Gulf nation.

The talks over oil come during a period when the world’s oil supply is beginning to fall short of demand. OPEC+ forecasters predict a global deficit of 3.3 million barrels a day in the fourth quarter, and many oil analysts now expect prices Brent to eventually top $100 a barrel.

The International Monetary Fund estimated earlier this year that Riyadh’s break-even oil price to balance its budget is about $81 a barrel. If Saudi Arabia keeps struggling to attract foreign investment to projects such as Neom, the break-even price could rise closer to $100, analysts say.

“It could prove challenging to convince Saudi Arabia to front load any significant energy assistance before a comprehensive deal is essentially done,” said Helima Croft, the chief commodity strategist at Canadian broker RBC.

FT : EU to loosen new rules on EV sales in attempt to defuse row with UK

EU to loosen new rules on EV sales in attempt to defuse row with UK
Brussels says it will interpret ‘made in Europe’ rules very loosely in 2024

The European Union is drawing up a plan to postpone tariffs on electric vehicle sales between the UK and the bloc for a year in an attempt to defuse a row over the new rules, which are due to come into effect in January.

Maroš Šefčovič, European Commission vice-president, told the Financial Times that Brussels would interpret “made in Europe” rules very loosely in 2024, giving carmakers more time to switch battery sourcing from Asia to Europe.

“We want to solve it and we are also discussing this with UK partners,” Šefčovič said, adding that he would be “very happy” if a deal could be struck before the December 31 deadline.

The post-Brexit Trade and Cooperation Agreement (TCA) dictates that tariffs of 10 per cent will be imposed on EVs shipped across the Channel if they have batteries substantially made outside Europe or the UK.

London has asked for a simple three-year postponement to the changes.

Šefčovič said the commission wanted to redefine what counts as European under the so-called rules of origin. “We do not have a precise timeline, but we are now working on our internal position discussions and we know that this is the pressing issue for the EU and the UK,” he added.

If finalised, the compromise will be welcomed by the industry on both sides of the Channel, who have warned the tariffs were likely to cost them billions and stifle electric vehicle demand.

Germany and about 10 of the 27 member states support the UK demand for a three-year delay to implementing the rules, while France remains opposed.

However, officials close to Thierry Breton, the French industry commissioner, said he considered the year-long postponement to be a workable solution as it did not reopen the Brexit deal or compromise EU ambitions to build European battery supply chains.

Under rules of origin, EVs traded across the Channel must have 60 per cent of their battery packs and 45 per cent of their parts by overall value sourced from the EU or UK or face 10 per cent tariffs. There are similar rules for the cathode chemicals and cells that comprise the battery pack and are mostly imported.

Šefčovič said: “What is important is how you actually do the counting of the rules of origin. We are in the process of developing this methodology and building up the battery industry in Europe and in the UK so I think we have to recognise as originating in Europe any part of that battery [that is European].”

He declined to offer further details, saying they were still being worked on.

But he was clear that the rules could only be postponed for one year because he wanted to encourage battery investment in the EU.

Sam Lowe, a trade expert at consultancy Flint Global, said: “One of the easiest ways to resolve this is to fiddle with the definitions. This could work if the thresholds are high enough to account for the high value of imported foreign chemicals. If not, it won’t.”

But he said it was unclear whether the UK would accept a one-year fix.

The UK government said: “We need a joint UK-EU solution to avoid consumers facing tariffs on electric vehicles from 2024 which do not apply to diesel cars.

“We have raised this with the European Commission and industry and are ready to work with them to find a solution within the existing structure of the Trade and Cooperation Agreement. The UK remains one of the best locations in the world for automotive manufacturing.”

FT : EU considers anti-subsidy probe into Chinese wind turbines

EU considers anti-subsidy probe into Chinese wind turbines
Competition commissioner says inquiry could follow similar move to challenge China’s sales of electric vehicles in Europe

Brussels is considering whether to investigate China’s use of subsidies to promote the country’s wind turbine manufacturers, a leading official said on Friday, despite the angry reaction from Beijing over a similar probe into electric vehicles.

Didier Reynders, the acting competition commissioner, said cheap Chinese imports could threaten European businesses.

“In the wind energy sector there are components that could be in competition with Chinese components. If there is a possibility of too much aid on the Chinese side . . . we could open an investigation in the same way [as electric vehicles],” he told France’s BFM TV.

Europe’s wind power companies have been lobbying for more support, arguing that cheap Chinese imports are pushing their own turbine manufacturers to the brink of collapse.

The move could come this month, three EU officials told the FT, as part of broader proposals aimed at boosting Europe’s wind industry.

It would be the second significant action against China is as many months, after commission president Ursula von der Leyen said in September Brussels would look into unfair practices in the electric vehicle market.

The move to challenge China’s increasing sales of electric vehicles in Europe prompted an angry response from Beijing, which called it a “naked protectionist act”.

A senior EU official said “sufficient elements” warranted a similar investigation into wind turbine parts. But the official acknowledged Brussels was concerned about retaliation.

“They already thought something announced in the speech of the president was too high,” the official said. “They will digest [the electric vehicles] one and adapt. If we add another, they might be really angry.”

The discussions come amid a planned visit to China over the coming days by Josep Borrell, the EU’s foreign policy chief, and Kadri Simson, the bloc’s energy commissioner.

The commission declined to comment.

Thierry Breton, the EU’s internal market commissioner, in September called for an anti-dumping or anti-subsidy investigation into wind turbines made in China.

“Chinese wind equipment manufacturers have been implementing an aggressive strategy to enter European markets,” he wrote, adding that Chinese manufacturers were offering European project developers steep discounts and the option to defer payments for up to three years.

Leading Chinese wind turbine manufacturers include Goldwind, Envision, Mingyang and Windey.

Brussels has already imposed tariffs on Chinese companies’ glass fibre fabrics, which are used in wind turbine blades. Industry concerns that the EU has become too dependent on Chinese green technologies have risen in recent years.

“[The region’s clean technology] will be manufactured outside of Europe, and Europe will simply swap its dependency on Russian gas for one on Chinese clean energy equipment,” WindEurope, a trade body for European industry, said earlier this year.

Another senior EU official said von der Leyen had started to back a strategy of supporting domestic industry and keeping out some Chinese imports.

“Without European manufacturing capacity, we don’t have control,” they said, adding that, without measures, the EU’s Green Deal of zero emissions by 2050 would be impossible to honour. “The president is starting to get it.”

Giles Dickson, chief executive of WindEurope, said broader proposals to boost the industry were being “actively discussed” by the commission and the sector. “You know what other tools [Chinese manufacturers] have at their disposal . . . [EU officials] know what we are up against,” he said, without explicitly referring to an anti-subsidy probe.

The broader proposals are set to include guidance to member states on providing direct financial support to the industry and improving auction designs for wind farms.

>>> US Close Dow +0.87% S&P +1.18% Nasdaq +1.60% Russell +0.81%

Closing Stock Market Summary
The major indices closed out the session near their highs, which had the S&P 500 (+1.2%) above the 4,300 level. The Nasdaq Composite, Russell 2000, and Dow Jones Industrial Average climbed 1.6%, 1.0%, and 0.9%, respectively.

Things looked different at the open, however, with stocks moving lower after a sharp move higher in Treasury yields. The 2-yr yield and 10-yr yield hit 5.13% and 4.87%, respectively, as participants eyed a much stronger-than-expected nonfarm payrolls gain of 336,000 (consensus 158,000) for September and ruminated over how that payroll strength might affect Fed policy.

Additionally, the nonfarm payrolls number for September was accompanied by upward revisions to July and August data that summed to 119,000 more jobs than previously thought.

The fed funds futures market now sees a 31.8% probability of another rate hike in November, up from 20.1% yesterday, and a 42.6% probability of another rate hike in December, up from 33.1% yesterday, according to the CME FedWatch Tool.

Treasury yields quickly pulled back from their post-employment report highs, however, due presumably to a sense that the bond market was oversold in the short-term and as participants found a bit of a silver lining in the understanding that average hourly earnings growth moderated to 4.2% year-over-year from 4.3% in August. The 2-yr note yield settled at 5.06%, which was still three basis points higher than yesterday. The 10-yr note yield rose seven basis points to 4.78%.

With Treasury yields coming off their highs, stocks reacted favorably, staging their own reversal that was likely helped by some short-covering activity. The mega cap stocks led the recovery, evidenced by a 1.7% gain in the Vanguard Mega Cap Growth ETF (MGK), but market breadth saw advancers move comfortably ahead of decliners as the rebound gained steam. Ten of the 11 S&P 500 sectors registered gains. The heavily-weighted information technology sector (+1.9%) led the pack while the consumer staples sector (-0.5%) was alone in the red.

As a reminder, the Treasury market will be closed on Monday for the Columbus Day holiday, which is also referred to as Indigenous Peoples' Day.
  • Nasdaq Composite: +28.3% YTD
  • S&P 500: +12.2% YTD
  • S&P Midcap 400: +1.0% YTD
  • Dow Jones Industrial Average: +0.8% YTD
  • Russell 2000: -0.9% YTD

Reviewing today's economic data:
  • September Nonfarm Payrolls 336K ( consensus 158K); Prior was revised to 227K from 187K; September Nonfarm Private Payrolls 263K ( consensus 150K); Prior was revised to 177K from 179K; September Avg. Hourly Earnings 0.2% ( consensus 0.3%); Prior 0.2%; September Unemployment Rate 3.8% ( consensus 3.7%); Prior 3.8%; September Average Workweek 34.4 ( consensus 34.4); Prior 34.4
    • The key takeaway from the report is that it bodes well for the economy. That is good news, yet that good news is apt to translate in the market's mind into a stubborn Fed standing on guard to possibly raise rates again but certainly not cut them anytime soon.
  • Consumer credit decreased by $15.6 bln in August (Briefing.com consensus $12.0 bln) after increasing an upwardly revised $11.0 bln (from $10.4 bln) in July.
    • The key takeaway from the report is that nonrevolving credit saw the biggest drop since December 2015, reflecting the tighter lending standards and reduced borrowing needs in the face of higher interest rates.

Looking ahead, there is no U.S. economic data of note on Monday.

FT : How Schonfeld fell into Millennium’s embrace

How Schonfeld fell into Millennium’s embrace
Struggling multi-manager hedge fund has turned to its larger New York rival for what would be the biggest tie-up of its kind

In March 2020 Schonfeld Strategic Advisors was rocked by the market turmoil unleashed by the pandemic.

The New York-based firm’s flagship hedge fund was down about 16 per cent and its prime brokers were asking it to put up more collateral, according to three people with direct knowledge of the matter. 

Needing to provide cash in response to a routine margin call as markets moved against it, Schonfeld considered its options. It had previously held informal discussions with Millennium Management about a potential tie-up, and one idea put on the table that month was for its much larger rival to provide some capital, two of the people said.  

While the talks with Millennium did not come to fruition, Schonfeld managed to shore up its position. That spring it raised about $2bn from investors, including in the Middle East and Asia, who had attributed the drawdown to growing pains.  

But now, following a lacklustre period of performance and third-quarter redemptions of $1bn, Schonfeld has restarted discussions with Millennium.

The Financial Times reported this week that the firms were in advanced talks over a tie-up that would see Millennium put billions of dollars to work with its smaller rival. The transaction, the largest deal of its kind, would be without precedent in the $4tn hedge fund industry.

“Is this a rescue act for Schonfeld?”, asked a senior executive at one London-based rival. “It’s quite a big step to take that much money from a peer. It’s not what you’d do if you had free choice.”  

The two firms declined to comment.

Schonfeld’s capitulation to Millennium reflects the changing fortunes of a hedge fund manager that has struggled to keep up with large rivals. Neither of Schonfeld’s two funds have made money this year, adding to an underwhelming 2022 in which the firm lagged far behind the likes of Ken Griffin’s Citadel and Millennium. 

Between them the two best-performing names in the multi-manager universe employ hundreds of teams of autonomous and highly specialist risk-takers, which trade a range of different strategies and operate within strict risk limits. 

Schonfeld began life in 1988 as a family office managing the money of founder Steven Schonfeld, a former stockbroker, and did not open up to external investors until 2015. Since then its assets have grown dramatically, as the multi-manager model it runs rose in popularity among investors.

The firm was among those that picked up inflows when bigger managers such as Millennium and Citadel were closed to new money with long waiting lists to get in. Schonfeld’s assets have doubled in the past two years, from about $6bn to $12bn. 

As assets have swelled, Schonfeld has expanded beyond its roots in computer-driven trading, adding discretionary macro, fundamental equity and fixed income strategies. It hired Colin Lancaster in May 2021 as global co-head of discretionary macro and fixed income to build out a business in this area. But the firm’s crown jewel is still its statistical arbitrage strategy, which uses algorithms to exploit patterns in securities pricing, investors say.



Schonfeld’s rapid expansion was partly enabled by the “pass-through” expenses model that is a defining characteristic of the multi-manager platforms. Instead of an annual management fee, the manager passes on all costs — including office rents, technology and data, salaries, bonuses and even client entertainment — to their end investors. The idea is that managers can invest heavily in areas such as staff and technology, with the cost more than offset by the resulting performance improvements.

One prime broker said Schonfeld had been “one of the biggest payers of sign-on bonuses” that can run into millions of dollars and are one of the tools employed to lure portfolio managers in the war for talent that is sweeping across this part of the industry. In the past two years, Schonfeld’s headcount has grown from about 600 to more than 1,000.

Schonfeld’s experiences reflect another key dynamic among the platforms. The multi-manager model is significantly more headcount-intensive than traditional hedge funds, and appears to have less operating leverage as firms grow bigger.

“As assets scale, headcount (and with it their cost base) tends to grow on a linear basis,” said a report last year by Goldman Sachs prime brokerage, which estimates that multi-managers account for just 8 per cent of the hedge fund industry’s assets but roughly a quarter of total headcount.

But crucially, if the amount of money a firm manages declines, costs do not fall in line with the decrease because it is hard for managers to cut spending at the same pace. That means fewer investors end up footing a larger bill that eats into returns, which could trigger more cash being pulled out.

“If assets start getting redeemed, the investors that are left behind get left with the brunt of the costs,” the prime broker says. This incentivises clients to “redeem quickly and not get stuck,” he added. “You don’t want to be the last person left holding the bag.” 

According to investors, the issue for Schonfeld is that it has doubled its assets and increased its cost base through a hiring spree — without putting up the performance figures to match.


Schonfeld is the third best-performing name in the multi-manager universe over the past three decades, behind only Citadel and Millennium. But its returns have tailed off over the past two years. In the first eight months of this year both its flagship fund and its fundamental equity strategy are roughly flat, and last year they returned just 4.5 per cent and 3 per cent respectively, according to investors. 

Millennium, meanwhile, recorded double-digit returns last year and is up 7.6 per cent in the first three quarters of 2023, while Citadel broke records with a $16bn profit in 2022 and gained 12.6 per cent per cent in the first nine months of the year. 

As returns have dwindled, the terms with which Schonfeld secured money have paved the way for future challenges. 

Since it opened to external investors, Schonfeld has offered clients monthly liquidity, which allows them to pull their money out once a month. This leaves the business vulnerable to mass redemptions, particularly with returns having declined and a higher-interest rate environment meaning investors can park their money in safer assets for a healthy return. 

To ensure the longer-term security of its business, Schonfeld has recently been offering clients a fee discount in return for new terms under which it would take them as long as two years to withdraw all their capital. More than half its capital is now locked up until the end of 2024, according to a person close to the firm.

In contrast, Millennium has been earlier and more proactive in taking steps to stabilise its business and prevent large-scale redemptions after suffering mass outflows during the financial crisis. In 2021 it returned money from a shorter-term share class that let clients exit in full in a year, and moved money to a longer-term share class that would take investors five years to exit in full.

Schonfeld’s 2020 experience prompted it to invest heavily in its risk management process and diversify away from its large equity exposure, according to one investor, who said what sets the firm apart from other multi-managers is its transparency.

Chief executive Ryan Tolkin “is very approachable”, they said. “If I wanted to talk to any of them I could and I value that because you don’t really get it from other large platforms.”

Tolkin has been credited with helping to build a business that has less of an eat-what-you-kill mentality than other multi-manager rivals. But investors say he is also adjusting to a rapidly growing firm that under his watch has expanded beyond its core DNA in systematic trading.

The 37-year-old, whose father Brad is close friends with Steven Schonfeld, according to a recent Business Insider article, joined the firm as chief investment officer in 2013 from Goldman, where he was a part of the investment bank’s corporate credit team and worked with Justin Gmelich, now a co-chief investment officer at Millennium. He was named to Schonfeld’s newly created role of chief executive in January 2021 while retaining his CIO title. 

Since news of the tie-up leaked, the two firms have been inundated with calls from clients. Their message to investors is that nothing has been finalised and they are still working out what the partnership will look like. But several options are being considered. 

Among them is a separately managed account for Millennium, or the larger firm taking all of Schonfeld’s capacity and kicking out its existing investors, according to people familiar with the situation. One of the people said it was important to preserve Schonfeld as an independent company given its distinct brand and culture.

People who know Izzy Englander, Millennium’s founder, say the 75-year-old will ultimately be keeping a close eye on the money invested with Schonfeld. He will want to make sure that “whatever money is running through them is going to be under Millennium risk controls,” said one person who worked alongside him for several years. “It’s a huge muscle flex by Millennium, they have capital and they’re neutralising a competitor.” 

For Millennium, a tie-up makes sense, according to several people familiar with the firm. The hedge fund has billions of dollars in long-term capital and by teaming up with Schonfeld it can quickly put money to work without the cost, time and complexity of hiring Schonfeld’s more than 100 investment teams. “If Schonfeld accelerates downwards quickly, Millennium will already have a hand in the pot and can see who is good,” said the prime broker.

For Schonfeld, a tie-up with Millennium brings it stable capital and economies of scale that come from tapping into the larger and more established firm’s infrastructure and systems. Millennium is wagering that this will help Schonfeld reboot its performance.  

“The existing portfolio managers at Schonfeld are probably fine with a tie-up,” said one top industry insider. “What’s the alternative, get fired soon and then get a job at Millennium anyway?”
