Context
These were routine, preplanned open-market sales under a 10b5-1 plan (transaction code S = sale). Such sales are commonly executed for diversification or liquidity and, by themselves, do not necessarily indicate a change in insider sentiment. Purchases by insiders tend to be more directly informative about bullish conviction.
