Global fundamental long-short hedge funds lost money every day in the week to Oct. 15, ending down 2.9%, though they remain up 14.3% year to date, according to Goldman Sachs prime brokerage data. Asia-focused stock pickers were hit hardest, down 6.8% in the first half of October and erasing more than half of their gains since a late-June peak. Goldman said the selling was mainly long liquidation rather than new shorts, with hedge funds net selling its Global AI Basket for six straight sessions by Friday, reversing net buying since early last year. South Korea's KOSPI fell more than 7% on Oct. 15 and Taiwanese stocks dropped more than 3%. The strategy's one-day loss exceeded 80 basis points three times in 2026 (Feb. 4, July 28 and Oct. 15), after never doing so from Covid through the end of 2025, with a hotter-than-expected US inflation reading as the trigger.

- AI trade reversal pierces star stocks across Asia
Asia's AI trade is under pressure as a selloff in US tech stocks raises worries that higher financing costs could slow the data center spending that supports regional chipmakers and suppliers. Oil's surge to US$110 a barrel has added inflation concerns, while US chip shares had their longest rout since 2008. A Goldman Sachs basket of Asian AI hardware stocks fell 11 percent last week, with Samsung Electro-Mechanics down 23 percent and Unimicron off 14 percent. CoreWeave's shares dropped 25 percent in a week as its bonds signaled distress, and Gartner warned that more than US$3.5 trillion of AI infrastructure spending could be impaired by 2030. Still, there is little sign so far that orders have weakened.

- Asian Stocks Fall on AI Funding Worries Despite China GDP Growth
Asian stock markets fell on Monday as worries over the cost and returns of AI investment outweighed stronger-than-expected Chinese data and lower oil prices. Japan's Nikkei dropped 1.2% after losing 5.4% last week, South Korean shares slipped 0.4% after a weekly decline of over 14%, and Taiwan fell 1.4%. China's third-quarter GDP grew 4.5%, slightly above expectations, while the yuan strengthened to 6.6828 per dollar. Brent crude fell 1.7% to $107.95 a barrel after Trump waived certain Russia sanctions, though Iran reported another tanker hitting a mine in the Strait of Hormuz. Gold gained 0.4% to $4,181 an ounce as falling bond yields boosted demand, while Goldman Sachs estimates five major AI hyperscalers could raise combined capital expenditure to about $1.2 trillion next year.
- Asian Stocks AI Funding Fears Weigh on Markets
Asian share markets turned cautious on Monday as investors questioned whether AI's enormous funding needs are sustainable, ahead of a busy week of earnings announcements. The euro came under pressure after riots across France, while a drop in oil prices eased pressure on bond markets and US stock futures. The oil price fall followed Donald Trump's decision to waive certain sanctions on Russia, but his later remark that a final decision was still pending left investors uncertain about the direction of US policy.
- AI stocks lead rebound on Wall Street as European markets drop
AI stocks recovered part of last week's steep losses on Wall Street on Monday, with the S&P 500 up 0.9% after its worst week since June and the Nasdaq up 1.7% on technology strength. Most U.S. stocks outside AI and tech were falling, while the Dow gained a modest 0.2%, or 111 points, as of 11:30 a.m. Eastern. European indexes dropped more than 1%, with Paris down 1.5%, after violent weekend protests that could push governments to boost spending and pressure bond markets. The 10-year Treasury yield rose to 5.12% from 5.09%, while Brent crude fell 1.4% to $108.35 a barrel. Cleveland-Cliffs jumped 15.1% after reporting a bigger-than-expected quarterly profit.

- Jensen Huang: “Two Gigawatts to Us Is Like $80 Billion.” 43 New Gigawatts Coming in 2027
Nvidia CEO Jensen Huang said two gigawatts of AI capacity, like the ones Nvidia announced in Australia, are worth about $80 billion to the company, up from about $18 billion per gigawatt previously. He attributed the increase to Nvidia now selling far more of each data center, including networking, CPUs, storage and security, not just GPUs. Citing SemiAnalysis's Dylan Patel on the BG2 podcast, Altimeter Capital's Brad Gerstner said 43 gigawatts of new AI compute will come online next year. At about $40 billion per gigawatt, Nvidia would need around 17 gigawatts to reach the $692 billion revenue estimate for fiscal 2028, though Huang said land, power and data center buildings are the main obstacles to the build-out.
- The Investment Case for JPMorgan Chase & Co. (JPM)
Diamond Hill's Large Cap Strategy returned 3.18% net of fees in Q3 2026, outperforming the 2.61% return of the Russell 1000 Value Index, and added JPMorgan Chase as a new holding. The firm said JPMorgan's scale should support continued technology investment that improves efficiency, helping contain expense growth and drive operating leverage. It expects below-average returns across the market due to high equity valuations, though attractive bottom-up opportunities remain. As of October 16, 2026, JPM closed at $339.72, with a $903.04 billion market cap, up 5.43% year-to-date and trading in a 52-week range of $279.10 to $366.50. Hedge fund portfolios holding JPM fell to 113 at the end of Q2 from 131 the previous quarter.
- Strive buys $335M in Bitcoin, boosting holdings to 36,818 BTC
Bitcoin treasury company Strive bought 4,045 BTC for about $335 million last week, raising its total holdings to 36,818 BTC, according to a Monday SEC filing. The purchases were made between Oct. 12 and 16 at an average price of $82,803 per coin, including fees. That makes Strive the fourth-largest publicly traded corporate Bitcoin holder, ahead of MARA Holdings, with reserves worth about $3 billion. The company also received about $369 million from warrant exercises and issued 13.7 million common shares, and it priced a $630 million offering of SATS preferred stock carrying a fixed 15% annual dividend, with proceeds that could fund more Bitcoin purchases. ASST shares rose about 7.7% to $25.95 in late-morning trading Monday.
