This week's sharp decline in tech stocks not only ended the year's hottest AI trading rally but also exposed another facet of modern financial market speculation mechanisms: when market sentiment reverses, high-leverage investment products built around hot thematic trends can amplify the downside in sync.
The sell-off in AI chip stocks by retail investors quickly spread to Asian and U.S. markets, severely impacting several leveraged ETFs and dragging down recently listed SpaceX-related funds. Concurrently, the weakening share price of MicroStrategy Inc (MSTR) has put pressure on a series of investment products built around Bitcoin, impacting the crypto asset market.
On the surface, the assets that suffered heavy losses this week appear unrelated. In reality, they are all products of the same phenomenon in the current bull market: high-leverage, high-frequency, low-barrier investment tools crafted around the market's hottest investment themes.
In recent years, nearly every market hotspot has spawned a complete ecosystem of financial products, including leveraged ETFs, options, digital asset derivatives, and prediction markets. While these products differ in structure, their common feature is enabling investors to bet on popular trades with higher leverage, faster speed, and more concentrated exposure.
Boston College behavioral finance professor Samuel Hartzmark noted that if retail investors widely desire access to certain high-risk, high-leverage investment tools, the market will ultimately continue launching related products to meet that demand, even if these tools may not truly benefit investors.
However, this week the market demonstrated the power of this mechanism operating in reverse. As investors began exiting leading AI stocks due to high valuations, the financial products designed to magnify gains began amplifying the entire deleveraging process.
The South Korean market became the clearest example. Local retail investors have recently been keen on purchasing leveraged ETFs that offer two or even three times the daily return of AI chip stocks. As the AI theme cooled, several popular local leveraged products fell over 20% this week, once again highlighting how leveraged products can rapidly magnify losses when trends reverse.
The impact did not stop in Asia. Wall Street's recent hot new topic, SpaceX (SPCX), also serves as a typical case. Leveraged funds related to SpaceX have attracted nearly $1 billion in inflows since their launch this month, but the products have fallen approximately 40% since inception. Many investors who chased the rally after the IPO hype effectively entered the market after most of the gains had already occurred.
Data shows that the global leveraged ETF asset base now exceeds $270 billion, with over $200 billion in the U.S. and more than $45 billion in Asia. As assets under management continue to grow, these products have become a significant source of passive buying and selling pressure in markets.
Barclays noted that the recent rebalancing trade size of U.S. leveraged ETFs has risen to several times the long-term average, and their mechanical buying and selling can significantly influence the movements of related stocks and indices.
This week, major U.S. benchmark indices broadly weakened, with the S&P 500 down nearly 2% and the Nasdaq 100 falling over 4%.
Simplify Asset Management portfolio manager Christopher Getter stated that the growing array of speculative products allows investors to easily bet on a company's future performance without truly understanding its business model. Using SpaceX as an example, he pointed out that current market valuations already embed expectations for high growth for many years ahead, while limited float and potential future index inclusion-driven technical flows are continually eroding the importance of traditional valuation frameworks.
"When fundamentals reassert themselves as the dominant market factor, smaller investors are likely to be the first to feel the impact," he said.
A similar situation is unfolding in the cryptocurrency market. In recent years, MicroStrategy has evolved from a simple Bitcoin-holding company into a key platform for building financial products around Bitcoin investment. Investors can participate not only through common stock but also via different instruments like ETFs and preferred shares, all betting on the same trade thesis. When market sentiment reversed, these products faced simultaneous selling pressure, further exacerbating stress in the digital asset market.
Leveraged long/short ETFs for MicroStrategy launched in 2024, despite attracting billions in inflows, have each fallen over 90% since inception. Meanwhile, the company's issued preferred shares have also fallen below par value, challenging the logic of investors seeking Bitcoin exposure through fixed-income products.
F.L.Putnam Investment Management chief market strategist and portfolio manager Ellen Hazen said this phenomenon is a classic Wall Street business model in a bull market. "The market will keep launching products that cater to investor demand," she said. "Many financial products don't really need to exist, but they still get sold."
Analysts believe these products are not the root cause of the current market downturn, but they reveal that the ongoing bull market is increasingly reliant on a few hot themes like AI, specific tech stocks, and digital assets. As more leveraged tools continue expanding around the same investment logic, they are profoundly influencing investor sentiment, fund flows, and market pricing mechanisms, amplifying both rallies and pullbacks.
Ocean Park Asset Management chief investment officer James St. Aubin stated these products are continually adding a "casino" element to the markets. "I would hope these products only attract a small number of investors, but judging by the fund flows, that group is growing rapidly," he said. "Anyone using leverage should understand they are playing with fire."
