Corporate insiders have not been this bearish on the stock market in more than 20 years, according to a MarketWatch analysis of insider trading data, a warning signal that has historically preceded weaker returns for equities.
In a column published Friday, MarketWatch’s Mark Hulbert wrote that insider sentiment has reached its most pessimistic level in over two decades, with executives and directors selling shares at a pace that dwarfs insider buying. Insider transactions are closely watched by investors because company officials are assumed to know their own businesses better than anyone else.
The bearish insider posture comes after a volatile month on Wall Street. The S&P 500 is up about 9% in 2026, but the group of megacap technology stocks known as the “Magnificent Seven” is down about 1% this year, according to an analysis this week from asset manager Vanguard cited by CNBC, as investors rotate out of the AI trade into infrastructure builders, energy companies and chipmakers.
Insiders have plenty of reasons to sell that have nothing to do with their view of the market, including diversification, estate planning, taxes and compensation. Many sales also occur under prearranged 10b5-1 trading plans. Hulbert’s analysis focuses on the balance of open-market buying and selling by insiders, a measure designed to filter out those mechanical transactions.
Historically, extremes in insider sentiment have carried contrarian weight. Periods of heavy insider buying, such as late 2008 and early 2009, marked some of the best buying opportunities of the past two decades, while sustained insider selling has often coincided with market tops. The current reading suggests those who run America’s largest companies see less upside than at any point in the past two decades.
The signal is arriving as the Federal Reserve holds rates steady after this week’s policy meeting. Wall Street’s takeaway from the decision was that a rate hike is likely on the horizon, according to CNBC, a backdrop that could pressure equity valuations further if inflation remains sticky and long-dated yields keep climbing.
Investors who follow the insider signal should treat it as one input among many. Insider sentiment is an imperfect timing tool, and bearish readings can persist for months while stocks continue to rise. But when insiders are this uniformly cautious, strategists say it pays to at least ask what they are seeing that the market is not.
