The hedge funds that made 60% on the AI chip rally are now down 17% in July as $137 billion flees Asia

Asia-focused hedge funds that rode the AI chip rally to gains of 60% to 120% in the first half of 2026 have given back 12% to 17% in July as a $137 billion foreign exodus from Asian equities and a 31% drop in Nvidia B200 rental rates triggered a selloff in crowded semiconductor positions. The WT China Fund was down 17% for July through July 17 after a 120% gain through June, while Keystone Investors Pte lost 12% in July after a 63% first-half gain, according to Bloomberg. The rout accelerated after TSMC raised its 2026 capital spending plan to $60-$64 billion and the KOSPI fell 7.89% on July 2, with SK Hynix dropping 14.57% in a single session.

Asia's AI chip trade hasn't broken, but July showed you what happens when too much money crowds into the same three stocks at once. Wang Tongshu's WT China Fund was up roughly 120% through June. By July 17, Bloomberg reported, it was down about 17% for the month before fees. Keystone Investors Pte had posted a 63% gain in the first half of the year, then gave back 12% over the same July stretch. These aren't cautionary tales about amateur speculation. They are Asia-focused funds that read the AI trade correctly, sized into it heavily, and then paid the cost of staying in a crowded winner when everyone else needed the same exit. The pressure started in late June and early July, when the AI hardware trade stopped moving as one clean story. One signal came from the spot market for compute: several market reports using Ornn and cloud platform data showed Nvidia B200 rental rates falling from $6.11 an hour on May 30 to $4.22 by June 21, a drop of roughly 31%. Then TSMC raised its 2026 capital spending plan to $60 billion to $64 billion on July 16, up from $52 billion to $56 billion, while also lifting its sales outlook. You can read that as proof of demand. You should. But once a trade is priced for perfection, higher spending also makes investors ask a harder question: how much of the AI build-out turns into durable margin, and how much just becomes more supply? The concentration problem The deeper problem wasn't one catalyst. It was what the catalyst hit. Bloomberg has reported that TSMC was approaching 45% of Taiwan's Taiex index, while Samsung Electronics and SK Hynix together made up about 30% of South Korea's KOSPI. That's not diversified AI exposure. That's an index turning into a single-sector bet. You saw the consequence in Seoul. SBS News reported that the KOSPI opened down 4.8% on July 2 and briefly fell more than 6%, with Samsung down more than 8% and SK Hynix down more than 9% at one point. Seoul Economic Daily put the closing damage even more plainly: the KOSPI finished July 2 down 7.89%, Samsung closed 9.06% lower, and SK Hynix fell 14.57%. A few days later, Reuters reported another brutal session around SK Hynix's Nasdaq debut, with the memory chipmaker tumbling more than 15% in Seoul and the KOSPI dropping 9%. That is what concentration does. When TSMC rises, it pulls the Taiex higher, which pulls benchmark money toward Taiwan, which sends more money back into TSMC. The loop looks clever on the way up. It looks mechanical on the way down. The selling wasn't confined to hedge funds. According to LSEG figures cited by Reuters, foreign investors pulled a net $137.36 billion from Asian equities across South Korea, Taiwan, India, Indonesia, Thailand and Vietnam - and the Philippines - in the first half of 2026, the fastest six-month outflow in data going back to 2010. South Korea accounted for $70.8 billion of that, while Taiwan lost $29.6 billion. That isn't a small trim. It is global money cutting exposure to the markets that had become the cleanest public proxies for AI chips. Reuters also made an important point the more dramatic market commentary can miss: the withdrawals weren't a simple risk-off panic. Analysts cited by the outlet pointed to currency hedging and benchmark rebalancing, the dull mechanics that force funds to sell their biggest winners when positions become too large. Dull doesn't mean harmless. If you're sitting in the same three semiconductor names as everyone else, rebalancing can feel exactly like a stampede. China's quant funds were hit as well. A Bloomberg report republished by BBW said a quant fund run by Zhejiang High-Flyer Asset Management, the firm associated with DeepSeek founder Liang Wenfeng, fell 15.7% in the week ending July 17. That detail matters because the AI trade in Asia wasn't only TSMC, Samsung and SK Hynix. It also included Chinese model companies, server suppliers, memory plays, cooling companies and anything else investors could plausibly attach to the build-out. Where the money is going Fund managers rotating out aren't simply hiding in cash. Reuters reported that some investors have been looking toward cheaper Southeast Asian markets after the huge run in North Asian chip stocks. Vietnam and Indonesia didn't carry the same index concentration - nor did the Philippines - and none of them ran as hard. That gives them a different appeal now: less glory, less pressure. Here's the thing. The AI trade isn't over. TSMC raising capex to as much as $64 billion is not a bluff, and high-performance computing accounted for 66% of TSMC's second-quarter revenue, according to company figures reported by several outlets. Demand for AI infrastructure remains real. The problem is the price investors were willing to pay for the same narrow route into that demand. Frankly, anyone surprised by the speed of the unwind wasn't looking closely enough at the index weights. When one company can approach half of a national benchmark, the market stops behaving like a market and starts behaving like a levered expression of one argument. For six months, that argument was that AI hardware demand would justify almost any valuation. July didn't disprove that. It proved you can be broadly right and still lose money if you enter the door too late.
