How this was made
The 30-second read
Why it matters
Aggregated insider activity provides mixed signals: notable buys (CapsoVision, Corebridge) versus sizable sells (Diamondback, Robinhood). Traders should weigh the relative size and context of each transaction.
Market read
Insider trades can foreshadow near‑term price moves; the mix of buys and sells across sectors may create short‑term volatility.
What to watch
10b5‑1 plans can mask true intent; sales may be pre‑scheduled rather than sentiment‑driven.

Ticker impact
Director Eliyahou Harari bought ~1.76M shares of CapsoVision at $5.69, a $10M insider purchase disclosed on Sep 18.
