Key Takeaways:
Investors poured $45 billion into a hedge fund that returned 270 percent in five months — then watched it lose 67 percent in July.
Investors keep funneling money into fund managers who deliver extraordinary short-term returns, only to watch those same funds collapse, a pattern that has repeated across three decades of market history. Leopold Aschenbrenner's Situational Awareness hedge fund was up 270 percent through May and had amassed $45 billion at its peak before losing 67 percent in July, according to The Wall Street Journal.
"Luck and randomness are the likeliest—but least satisfying—explanations for extreme outcomes," the late psychologist Daniel Kahneman told Jason Zweig, the Intelligent Investor columnist at The Wall Street Journal. "Ordinary causes feel insufficient to explain extraordinary results."
The pattern spans generations. Cathie Wood's ARK Innovation ETF surged 153 percent in 2020, drawing $20 billion in new money, yet has trailed the S&P 500 by an average of nearly 23 percentage points annually since the end of 2020. Ryan Jacob's Jacob Internet Fund, launched in late 1999, attracted nearly $300 million in the opening weeks of 2000 after a 216 percent annual return at his previous fund, then lost 70 percent in 2000 and 56 percent in 2001.
The cost of chasing performance is steep. Aschenbrenner's fund lost 67 percent in July alone, while ARK Innovation has underperformed the benchmark by roughly 23 points a year for five years. The Jacob Internet Fund has lagged the S&P 500 by nearly 14 percentage points annualized since its launch.
Zweig, who has written The Intelligent Investor column since 2003, argues the behavior is rooted in what Kahneman called magical thinking. "Stories trump statistics," the psychologist said. When a manager doubles or triples other people's money in a few months, intuition tells investors the person must be a miracle worker, even when the returns are the product of luck and concentrated risk.
The three cases share a common arc: a young manager, a spectacular run, a flood of inflows, then a crash. Aschenbrenner, a former OpenAI researcher, built Situational Awareness into a $45 billion fund on the back of a 270 percent gain through May. ARK's Wood became a household name after her flagship fund returned 153 percent in 2020, drawing $20 billion in new money by year-end. Jacob, then 29, launched his internet fund at the peak of the dot-com bubble and collected nearly $300 million in weeks.
The financial damage is measurable. ARK Innovation has trailed the S&P 500 by an average of nearly 23 percentage points annually since the end of 2020, meaning a $10,000 investment would have lagged the benchmark by thousands of dollars. The Jacob Internet Fund lost 70 percent in 2000 and 56 percent in 2001, and has underperformed the S&P 500 by nearly 14 percentage points annualized since launch.
Zweig points to a Willa Cather quote inscribed on a sidewalk plaque near the New York Public Library: "There are only two or three human stories, and they go on repeating themselves as fiercely as if they had never happened before." Among investors, one of those perennial stories is the young swashbuckling genius who comes out of nowhere, racks up gigantic gains on risky bets, attracts massive amounts of money, then crashes and burns.
"That story goes on repeating itself as fiercely as if it had never happened before," Zweig wrote, "and I suspect it always will."
For investors, the lesson is that extraordinary returns are rarely repeatable, and the inflows that follow a hot streak often arrive just before the reversal. The same behavioral bias that drew $20 billion into ARK in 2020 and $300 million into Jacob's fund in 2000 is now pulling money into Aschenbrenner's fund — with the same risk of a sharp drawdown.
