Aspex Management, one of Asia's largest hedge funds, suffered a rare and sharp monthly loss in October, dropping about 16% as a selloff in AI-related stocks battered the kinds of companies it tends to own. The Hong Kong-based stock picker, which manages roughly $14 billion, focuses on pan-Asian equities, and its concentrated bets in technology and AI-linked names left it exposed when investor sentiment turned.
Despite the brutal month, the fund was still up about 9% for the year through October, according to Reuters. That means earlier gains absorbed some of the shock, but the October stumble underscores how quickly a crowded growth theme can reverse.
What happened in October?
October was ugly across the same AI-heavy markets Aspex fishes in. Reuters cited declines in the Nasdaq Composite, Taiwan's benchmarks, South Korea's KOSPI, and China's Star 50 index as investors began questioning whether massive spending on artificial intelligence will actually translate into profits. The selloff was global, but Asia felt it acutely.
Goldman Sachs data cited by Reuters showed Asia was the worst-performing region for equity long-short hedge funds last month, with Asian managers down 8.3% on average versus a 2.5% drop globally. That gap highlights how concentrated Asian funds have become in the AI trade, and how quickly that concentration can hurt when sentiment shifts.
The broader context: AI stocks had been on a tear for much of the year, driven by enthusiasm over generative AI and the infrastructure needed to support it. But as valuations climbed, any sign of weakness—whether from disappointing earnings, regulatory concerns, or simply profit-taking—can trigger a sharp pullback. The AI selloff also drove safe-haven currencies higher, a sign that investors were rotating out of risk assets.
What it means for investors
For everyday investors, Aspex's October loss is a reminder that even the most sophisticated fund managers can get caught off guard by sudden market shifts. It also illustrates the risks of piling into a single theme, no matter how promising it seems.
But the bigger implication may be for the markets themselves. A drawdown of that size doesn't just sting reputations; it can shrink how much risk a fund is willing, or even allowed, to run. After big losses, managers often tighten internal risk limits and reduce gross exposure, which usually means trimming positions and paying down leverage. If clients redeem, the need for cash can accelerate that process, and funds often sell their most liquid holdings first.
Because Aspex has been a cornerstone investor in Hong Kong listings and has backed AI-adjacent firms like MiniMax and optical transceiver maker Zhongji Innolight, its de-risking could land on the same AI-linked stocks already seeing outflows. That could add further downward pressure on those names, and it could also make IPO demand and early aftermarket support look less dependable when a major anchor steps back.
For investors holding AI-related stocks, the key takeaway is to be aware of the potential for forced selling by large funds. When a big player needs to raise cash, it often sells its most liquid positions first, which can create a cascade effect. Asia's AI-linked stocks have already tumbled on US selloff and regulation fears, and further de-risking could extend those losses.
It's also worth noting that not all AI stocks are created equal. Some companies have real earnings and cash flows, while others are more speculative. The October selloff hit the latter hardest, but even solid names were caught in the downdraft. The KOSPI's 8% plunge and circuit breaker triggered by chip stock collapses shows how severe the selloff can be in markets with heavy tech weightings.
What to watch next
Investors will be watching whether Aspex and other Asian hedge funds continue to reduce risk in the coming weeks. If the AI trade stabilizes, the selling may subside. But if sentiment remains fragile, further drawdowns could prompt more forced selling, creating a vicious cycle.
Also on the radar: the broader economic backdrop. The October jobs report is expected to show a modest hiring rebound, which could influence interest rate expectations and, in turn, the appetite for growth stocks. If rates stay higher for longer, that could keep pressure on high-valuation tech names.
For now, the lesson from Aspex's October is that even the best stock pickers can have a bad month. The fund's year-to-date gain of 9% shows that long-term performance can still be solid, but the volatility is a reminder that investing in concentrated themes carries risk. Diversification and a long-term perspective remain the best defenses for everyday investors.
