The Danger of Catching Falling Knives

Why Buying the Dip Can Destroy Your Portfolio

Even before the geopolitical chaos in the Middle East triggered this month's extreme volatility, underlying market currents were deeply unsettled. The rapid, disruptive evolution of artificial intelligence has repeatedly sent various blue-chip equities into sudden tailspins.

Whenever a major ticker nosedives, financial headlines typically scream about "massive selloffs." Yet, for every unloaded share, a willing buyer stepped up, betting the newly slashed price represented a brilliant bargain. Were these bargain-hunters making a fatal error?

According to one of Wall Street's most time-honored maxims—"never try to catch a falling knife"—they absolutely were. Furthermore, a massive pile of academic research backs up this old adage.

Alexander Hübbert, a quantitative researcher pursuing his Ph.D. at Stockholm University, recently crunched the numbers, and the results are undeniable. His study examined 4,174 British equities between the years 2000 and 2026. He isolated stocks that had retreated from their all-time highs by specific increments (5, 10, 15, and 20 percent) by month's end, and then tracked their performance against the broader market over the subsequent 12-month period.

The data is brutal. Equities that suffered a 5% drawdown went on to underperform the broader market by an average of 6 percentage points. A 10% pullback led to an 8.6 percentage point lag, and a 15% plunge resulted in a massive 12 percentage point underperformance. Simply put: the faster the knives fell, the deeper the financial wounds.

Momentum remains one of the most reliable forces in finance, operating just as powerfully on the downside as it does on the upside. Other quantitative strategies that attempt to buy equities near their 52-week lows yield similarly depressing outcomes to Hübbert's findings.

Naturally, market rules have exceptions. Legendary investor Howard Marks, co-founder of Oaktree Capital Management, actually advocates for buying during a crash in his book Mastering the Market Cycle. He notes that most portfolio managers are paralyzed by fear while an asset is plummeting. The catch? "When the dust has settled and investors’ nerves have steadied, the bargains will be gone."

Marks boasts an elite track record in distressed-credit investing; in fact, Warren Buffett publicly admits to reading his memos. However, this perfectly illustrates the trap: blindly grabbing a recognizable stock just because it tumbled is vastly different from possessing a highly sophisticated valuation model amidst a panic. Simply put: you are not Warren Buffett.

As the old saying goes: "The young man knows the rules, but the old man knows the exceptions."

Today in Financial History

On this exact date in 1792, Wall Street experienced its first true financial crash. Dubbed the original "Black Monday," 6% Treasury bonds shed 10% of their value, and shares in the Bank of the United States plummeted 12%. The panic was triggered by William Duer, a prominent speculator and close friend of Alexander Hamilton, who had massively over-leveraged himself and was facing debtors' prison.
