Consider buying Eastman Chemical (EMN), where an unprecedented 11 insiders are purchasing shares for the first time in the company's history following a 25% stock decline. Another strong buy signal comes from Residio Technologies (REZI), as a director with an excellent track record just made a $1 million purchase after his previous buys preceded the stock doubling. Conversely, be cautious with Frontier Group Holdings (ULCC), where the CEO's recent large sale follows a historical pattern of the stock dropping 40% on average in the subsequent three months. Similarly, the CEO of Affirm Holdings (AFRM) initiating his first-ever selling plan is a major red flag, especially as a similar move by another executive in 2021 preceded a 90% stock collapse. These insider sales at ULCC and AFRM suggest leadership believes recent stock rallies are overextended.
