s&p 500 rapid rise history just flashed a warning that mimics the week before the 1987 Black Monday crash, and your 401(k) could be the next victim. The stock market’s record-breaking sprint over the last three months—one of the fastest climbs in a century—is statistically identical to the pattern that preceded the largest single-day crash in Wall Street history. For everyday investors, this means if you haven’t rebalanced your retirement accounts or trimmed your winners, you’re gambling your grocery money on a pattern that has historically ended badly. The S&P 500 has surged over 15% in just 60 trading days, and while it feels like easy money, data shows the last three times this happened, the market dropped an average of 20% within six months.
