Context

Sales by officers can be for many personal reasons (diversification, taxes, liquidity) and are not by themselves an indicator of company performance; purchases tend to carry more interpretive weight. The Form 4 shows standard open-market sale codes (S) — no complex derivatives or option exercises in this report.
