Mark Massey plays the game with a strategy best described as Extreme Concentration. He isn't interested in diversifying just to look safe; he picks the absolute best horses and bets the farm on them.
His philosophy revolves around owning wide-moat compounders that can dominate for decades. The conviction here is wild—his top three holdings alone make up nearly 80% of his entire book.
Amazon (AMZN) is his absolute kingmaker, commanding over 30% of the portfolio, flanked by massive stakes in Microsoft (MSFT) and the aerospace compounding machine TransDigm (TDG). Massey proves that if you really know what you own, you don't need a hundred different stocks to win.
