Insider activity provides a window into how executives and significant shareholders are managing exposure to their company stock. Purchases by insiders, especially when made with personal capital or under 10b5-1 plans, can be interpreted by some market observers as a signal of confidence in a company’s prospects. Conversely, sales may reflect concerns about valuation or simply be planned liquidity events, including those executed under prearranged plans. These transactions should be considered one data point among many - along with fundamental analysis, industry-specific considerations and wider market conditions - when assessing investment decisions.
