Context
Insider sales can be routine (diversification, liquidity, pre-set trading plans) and do not necessarily reflect management’s view of the company. Purchases generally carry more weight for signaling confidence. If you follow insider activity, watch for patterns over time (multiple insiders selling or a mix of buys and sells) and check the full Form 4 for any disclosures (10b5-1 plans or holdings after the trade) before drawing conclusions.
