Billionaire investor David Tepper's Appaloosa Management disclosed a new position in American Airlines (AAL) during the second quarter of 2026. The fund acquired 7.50 million shares, valued at approximately $135.53 million as of June 30, 2026, giving it a 1.75% weight in its reported portfolio. This investment was revealed in a quarterly 13F filing with the SEC, which is a delayed disclosure and does not reflect a same-day trade.

This move marks a notable entry into the airline industry for the prominent hedge fund. The investment coincided with a period where American Airlines reported its highest-ever quarterly revenue. Appaloosa's filing also revealed a new stake in aircraft manufacturer Boeing, suggesting a broader interest in the aviation sector during the second quarter. No public comments from Tepper regarding the specific motive for the investment have been released.
