Context
These were outright sales under a pre-established 10b5‑1 plan, which is a common mechanism insiders use to sell holdings on a preset schedule and is typically viewed as routine rather than a direct signal about company prospects. Sales (S) differ from purchases, which are generally considered a stronger bullish indicator.
