Context

• A 10b5-1 trading plan allows insiders to pre-set trades to occur at specified times or conditions; sales under such plans are typically prearranged and may reflect scheduled liquidity rather than a change of view on the company. For retail investors, single insider sales—especially under a 10b5-1 plan—are informative but not definitive indicators of company performance.
