Financial Editorial: Enhancing the Awareness of Knowing When to Stop is the Most Powerful Risk Control Measure

原文:一财社论:提高知止的认知是最有力的风控

Summary of Key Points

This news story recounts the ordeal of an “AI stock god” fund that became the target of Wall Street’s attention: The SALP fund, founded by former OpenAI employee Asher Brenner, raised $45 billion through AI-themed investments and achieved a staggering 439% return in the first half of the year. However, due to the use of four times leverage (a combination of its own funds and borrowed capital, resulting in a total portfolio value of $120 billion), the fund was forced to liquidate its assets by brokers when AI stocks declined by 25%. Other hedge funds took advantage of this situation to acquire its holdings. Citadel Investment managed to purchase the fund’s shares for $16 billion at a discount, preventing its liquidation, and the fund has since maintained an annual return of 80%. This incident serves as a reminder to investors and regulators: Leverage should be used in conjunction with a proper understanding of the market; marginal investors can significantly impact market pricing; and market volatility is not necessarily a bad thing.

Detailed Analysis

1. Four Times Leverage: An “Accelerator of Risk”

SALP’s aggressive leverage strategy was at the heart of this crisis. What does four times leverage mean? Simply put, if you have $1, you borrow another $3 to invest in stocks, creating a total portfolio value of $4. When things go well, you can potentially earn four times that amount; however, when losses occur, you could lose four times as much—potentially wiping out all your capital.

In SALP’s case, it had $45 billion in assets (including $10 billion in equity from the AI company Anthropic and $30 billion in cash). With four times leverage, its total portfolio reached $120 billion. When AI stocks fell by 25%, this resulted in a loss of $30 billion—exactly wiping out its cash reserves. Fearing that they would not be able to recover the borrowed funds, brokers enforced a liquidation of SALP’s assets. Other hedge funds saw this as an opportunity to go short (selling first and then buying back at a lower price), further driving down stock prices and increasing SALP’s losses.

2. Understanding Is the Key to “Safety”: Leverage Should Not Exceed Your Knowledge

SALP survived not because of its clever use of leverage, but because its founder had a deep understanding of AI. The Anthropic equity it held was considered a valuable asset, as Anthropic is a leading AI company on par with OpenAI. However, the leverage ratio exceeded the fund’s ability to withstand market fluctuations. AI stocks are highly volatile (25% declines are common), and four times leverage made SALP vulnerable to such losses.

This highlights that leverage should not be used recklessly; it must be in line with your understanding of the industry. If you have a thorough knowledge of the AI sector and can identify valuable companies, you can withstand certain levels of volatility. But if you simply follow the trend and use high leverage, you are exposed to significant risks.

3. Marginal Investors: The “Decisive Minority” in Market Pricing, Both a Double-Edged Sword

The news suggests that market pricing is influenced by marginal investors—those who account for around 5% of the market but are highly sensitive to changes. The hedge funds that targeted SALP were examples of such investors. They sensed the impending liquidation and went short in advance, driving price movements.

Marginal investors are important because market prices are determined by the last transaction, and they often make that final decision. However, they can also introduce risks, such as excessive speculation and market manipulation. Regulators need to create a better environment for them—by providing more trading tools, transparent information, and opportunities for informed risk assessment, rather than simply trying to suppress their activities.

4. Volatility Is Not the Enemy: It’s a Normal Part of Market Functioning

Many people fear market volatility, but it can be seen as a natural process of “trial and error.” For instance, fluctuations in AI stocks help identify which companies are truly profitable and which are bubbles. If markets remain stable forever, no one would trade, preventing the allocation of resources effectively. The SALP incident illustrates this: its high-leverage strategy led to huge gains during a bull market but exposed it to significant losses during a bear market, serving as a mechanism for the market to correct excessive speculation.

5. Lessons for Regulators and Investors

This case serves as a warning to both investors and regulators:

  • For Investors: Leverage is a tool, not a gamble. Before using it, ask yourself how much you understand the industry and how much volatility you can tolerate. Don’t use leverage just to seek quick profits.
  • For Regulators: Regulate the behavior of marginal investors while not stifling their entrepreneurial spirit. Provide tools for risk management (such as stop-loss mechanisms) and ensure transparent information to allow markets to function effectively without losing control.

In summary, the SALP story emphasizes that there is no such thing as a guaranteed profit in the capital market. Respecting the market, enhancing understanding, and using leverage responsibly are the keys to long-term success.
