Context
These were outright sales (dispositions). Sales can be for many reasons (liquidity, portfolio rebalancing, etc.); they do not by themselves indicate company performance or insider sentiment. For purchases or option exercises, filings can be more directly indicative of insider conviction; this report documents routine insider selling activity.
