Today’s Largest Unscheduled Trades

There were 318 new insider trades filed.

No insider trades were flagged as High Signal. I really wanted to add Aptiv (APTV) because it is in an industry with significantly above-average inside buying (Automotive Components), trading below its median EV/EBITDA multiple, and has multiple insiders buying the post-earnings dip. However, the mgmt team continues to be wrong on their forecasting, and I’m just not convinced they are finally going to be correct this time.

Our system gave high scores to 4 insider purchases (I shared our system’s notes on those in the High Scoring Purchases - Quick Notes).

We also found 2 insider purchases from insiders who average 20%+ 1y returns.

CEO Watcher Premium subs can see all of these notes in later sections of this email.
