10% owner THOMAS W POWELL sells 49,778 shares of POWL for $25.0M at $502.23; stock down -8.5% from 52-week high, cross-ticker track record shows 100% well-timed sells (avg 90d: -72.6%).
Thomas W Powell, a 10% owner, executed a $25.0M sale of 49,778 shares at $502.23, reducing his holdings from 648.5K to 598.7K shares (-7.7%). The transaction occurs with the stock at $180.86, down -8.5% from its 52-week high of $197.63. Powell's cross-ticker track record across 20 prior open-market sales shows an exceptionally strong pattern: average 90-day return of -72.6% and a 90d well-timed rate of 100.00%, meaning all prior sales were followed by subsequent declines. However, his five most recent trades at POWL itself (all sells from February-March 2026) show uniform 30-day losses of -71.8% to -72.2%, with no 90-day outcomes yet measurable. The apparent discrepancy between his strong cross-ticker timing and the simultaneous string of underwater recent trades at this same ticker warrants attention—this may represent either a regime shift specific to POWL or a clustering effect requiring deeper examination of whether recent market conditions have changed his predictive signal value.
