Context Sales executed under a Rule 10b5-1 plan are prearranged trades set up in advance and can be made regardless of current views on the company; they are commonly used for planned diversification or liquidity and should be interpreted differently than ad hoc insider sales. For retail investors, purchases generally carry more weight as indicators of insider confidence; sales alone, especially under a 10b5-1 plan, are not definitive evidence of insider sentiment.
