Insiders sold stock recently, but they haven't been buying. And even if we look at the last year, we didn't see any purchases. But since Kosmos Energy is profitable and growing, we're not too worried by this. Insider ownership isn't particularly high, so this analysis makes us cautious about the company. So we'd only buy after careful consideration. While we like knowing what's going on with the insider's ownership and transactions, we make sure to also consider what risks are facing a stock before making any investment decision. Every company has risks, and we've spotted 1 warning sign for Kosmos Energy you should know about.
