Context

• Sales by insiders can be routine (e.g., pre-set 10b5-1 plans, tax/liquidity needs) and do not necessarily signal a change in company outlook; the presence of a 10b5-1 plan indicates the trades were pre-planned. Purchases generally carry more weight for signaling, while planned sales are common for directors.
