Is a Stock Market Crash Coming? Insiders Are Leaving Faster Than They Have Since 2021

Concerns Arise as Insiders Sell Stocks Amid Market Optimism

The U.S. stock market has been sluggish for over three years now, but executives at major companies are suddenly offloading their shares at a rate we haven’t seen since last year.

Insider selling has surged, leading to the highest buy-to-sell ratio in five years, according to Maverick Equity Research. They pointed out on X.com that insiders seem to appreciate the current high valuations, likely because they are selling at favorable prices. Interestingly, during the extreme valuations of 2021, these insiders were quite savvy, selling off their holdings before the market downturn in 2022.

Timing, it seems, is a crucial factor. Since late 2022, the U.S. stock market has been buoyed by a strong AI-driven rally. The S&P 500 index saw impressive increases—23.3% in 2024 alone, followed by another 16% in 2025, and a decent 1.4% in January 2026, surpassing 7,000 points for the first time ever. Many investors appear to have stopped doubting the sustainability of the rally, but those within the companies seem to be a bit more skeptical.

And they’re not alone in their caution.

Recently, several prominent institutions and analysts have raised alarms about mounting risks in the market. Last quarter, the IMF specifically flagged that U.S. stocks, especially those tied to AI, were trading significantly above fundamental values, warning that “soaring stock prices heighten the chances of a chaotic correction.”

Fidelity International’s January 2026 Market Outlook echoed these concerns, noting an uptick in volatility across sectors as rising valuations and concentrated indexes lead to profit-taking.

Northern Trust Asset Management mentioned in a December 2025 commentary that U.S. stock valuations are on the rise compared to historical trends, with a narrow group of large-cap stocks continuing to drive index performance. They acknowledged that while there’s still potential for growth, the current dynamics of valuation and concentration are important to consider.

In summary, the situation is revealing. Insiders are selling off their stocks aggressively even as international organizations point out risks related to inflated valuations, concentration issues, and possible market corrections. While this doesn’t outright create a guarantee of a market crash, the actions of insiders have historically served as reliable early warnings, and right now, those signals are more pronounced than they’ve been since 2021.
