Insider purchases (SEC Form 4, open-market, last ~7 months) (TTEK)
1 purchase, $50K. Private placements, offerings, dividend reinvestment and employee stock purchase plan buys are excluded.
| Trade date | Insider | Role | Shares | Value | Avg price | Insider type |
|---|---|---|---|---|---|---|
| 2026-05-15 | Feeler Jeffrey R | Director | 1,900 | $50K | 26.41 | Too little history (no open-market trades in 2023–2025) |
Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.
