Frequently Asked Questions
What does it mean when insiders buy stock?
When corporate insiders purchase shares on the open market, it is often interpreted as a bullish signal — they are investing their own money alongside public shareholders. However, context matters: a purchase by a CEO carries more weight than a small buy by a lower-level employee, and cluster buying (multiple insiders buying simultaneously) is generally considered an even stronger signal.
Are insider sales bearish?
Not necessarily. Insiders sell shares for many reasons unrelated to their company's outlook — diversification, estate planning, tax obligations, or personal liquidity needs. Only open-market sales that are large relative to total holdings and not pre-scheduled under a 10b5-1 plan warrant serious attention as a potential bearish signal.
How does BC's composite score relate to insider activity?
The Blank Capital composite score reflects our quantitative assessment of a stock's quality, momentum, value, and other factor exposures. When insider buying aligns with a high BC score, it may reinforce a bullish case. When insiders buy a stock our model rates poorly, it can flag an interesting divergence worth investigating.
