HHH — Insider Trading Activity

Unusual activity. Recent buying at HHH is running noticeably above its trailing 11-month baseline. That doesn’t guarantee outperformance, but a step-change in insider behavior is worth investigating alongside the fundamentals. Who is buying. The most credible buyer in this window is the company’s Chairman ($1M–$5M), growing their stake by 35%. Overall credibility score: 63/100 (Medium).

By the numbers. 2 insiders filed 2 open-market purchases at HHH over the window, 26,000 shares in all at an average of $64.13 a share, most recently on September 23, 2026. On the other side, one insider filed 1 sale covering 13,495 shares at an average of $67.25, the latest on August 11, 2026. That puts the average sale 5% above the average purchase — worth checking against where the stock trades today. Buying over the window ran 39.5× the dollar value of HHH’s trailing 11-month baseline.
