As geopolitical tensions escalate and markets react with volatility, corporate insiders at several companies have been actively buying shares of their own firms in the days leading up to the conflict. This insider buying activity suggests executives see value in their companies' stocks despite the market sell-off, with the businesses' long-term outlooks remaining intact even as broader uncertainty rises.

Why it matters

Insider buying can serve as a valuable signal for investors during periods of market turbulence, as executives have unique insight into their companies' fundamentals and prospects. When insiders accumulate shares ahead of macro shocks, it suggests they believe the current stock price undervalues the long-term value of the business, providing a potential roadmap for opportunistic investors.

The details

Insiders at CoStar Group, Hamilton Lane, Vornado Realty Trust, and Claritev Corporation all made notable purchases of their companies' shares in the week before the recent escalation of geopolitical tensions in the Middle East. These firms operate in areas like commercial real estate data, private markets investing, New York office properties, and healthcare technology - industries that may be impacted by the broader uncertainty, but where the core business models and growth outlooks appear intact based on the insider buying activity.

  • Insider buying occurred in the week leading up to the attacks on Iran that began on March 5, 2026.

What they’re saying

“When insiders buy aggressively with their own money—especially ahead of a macro shock—it tells us something important. It tells us that at prevailing prices they believe the stock is undervalued relative to long-term prospects.”
