Context
Sales under a Rule 10b5-1 plan are typically pre-scheduled and are often routine liquidity transactions rather than immediate expressions of an insider’s current view of the company. For retail investors, purchases by insiders tend to carry more informational weight than routine sales; these transactions should be seen as scheduled disposals unless other information indicates otherwise.
