ETRA — Insider Trading Activity
Insider buying at ETRA has stepped up sharply against its own history, and it is the first open-market buying here in that whole period.
What this means for ETRA
Unusual activity. Recent buying at ETRA 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 a Director ($10M–$50M), growing their stake by 28%. That insider’s track record: past buys beat the S&P 500 3 of 6 times (avg +50% vs S&P over 6 mo). Overall credibility score: 68/100 (Medium).
By the numbers. 2 insiders filed 4 open-market purchases at ETRA over the window, 2,666,666 shares in all at an average of $15.00 a share, most recently on September 21, 2026. No insider sold ETRA stock on the open market in that period. It is also the first open-market insider buying at ETRA anywhere in that 11-month lookback.
