INV — Insider Trading Activity

Cluster buy signal. Multiple insiders independently writing personal checks for the same company’s stock is one of the stronger patterns in the Form 4 data — it usually reflects a shared view among people who see the numbers first that the shares are cheap. Historically, 3+ insider clusters have outperformed the broader market over the following 6–12 months. Who is buying. The most credible buyer in this window is the company’s Chairman ($100K–$500K), growing their stake by 7%. That insider’s track record: past buys beat the S&P 500 1 of 1 time (avg +26% vs S&P over 6 mo). Overall credibility score: 64/100 (Medium).

By the numbers. 4 insiders filed 4 open-market purchases at INV over the window, 536,000 shares in all at an average of $1.51 a share, most recently on August 20, 2026. No insider sold INV stock on the open market in that period.
