Insiders who bought US$16.1m worth of Cartesian Therapeutics, Inc. (NASDAQ:RNAC) stock in the last year recovered part of their losses as the stock rose by 15% last week. The purchase, however, has proven to be a pricey bet, with losses currently totalling US$5.0m.

While insider transactions are not the most important thing when it comes to long-term investing, we do think it is perfectly logical to keep tabs on what insiders are doing.
