US technology sector ETF sees record insider buying as 28 executives purchase stock

The people who know their companies best are putting their own money where their quarterly earnings calls are. Twenty-eight US tech executives have purchased shares of their own companies over the past six months, pushing the insider buying velocity for the Technology Select Sector SPDR Fund (XLK) to its highest level since data tracking began in 2010.

That’s not a typo. The number has doubled since early 2026, according to SentimentTrader data, and it represents the strongest wave of insider accumulation the tech sector has seen in at least 15 years.

From sellers to believers

Just last year, this same cohort of mega-cap tech executives was doing the exact opposite. In 2025, insiders collectively offloaded more than $16B in shares, with heavyweights like Jeff Bezos leading the exodus.

Insider buying has long been considered one of the more reliable signals in equity analysis. The logic is straightforward: executives sell stock for all kinds of reasons, from diversification to divorce settlements to buying a third vacation home. But they buy for only one reason. They think the price is going up.

Reading the signal through the noise

SentimentTrader frames the current buying wave as a potential bullish signal, but context matters. The AI valuation debate hasn’t gone away. The fact that insiders are buying despite these concerns is arguably what makes the signal interesting. They’re not waiting for the valuation debate to resolve before committing capital.

The $16B in insider selling during 2025 coincided with a period of heightened volatility across both equities and crypto. The reversal into record buying could signal that the people closest to the fundamentals see stabilization, or even acceleration, ahead.
