Unprecedented insider buying at Eastman Chemical (EMN) and Eastern Bank Shares (EBC) signals strong bullish conviction from management after recent price drops. Eleven insiders at EMN and five at EBC made rare, coordinated purchases, suggesting they believe their stocks are significantly undervalued. Conversely, insiders at Wheels Up (UP) are selling after a 100% price increase, with key sellers historically timing sales before average stock drops of 25-50%. The former CEO of Snowflake (SNOW) also made his second-largest sale ever, a pattern that has previously led to poor stock performance over the following six to nine months. Lastly, the CEO of Enact Holdings (ACT) made his first-ever sale, a bearish indicator given his strong track record of timing trades.
