New Years Eve 2024 was a party to remember for the 4% Club (stocks with a minimum 4% weight in the S&P 500).

For most of the past five years, membership had been limited to two or three companies. Before that, the Club’s March 2000 high-water mark of three firms seemed unobtainable—and, with a little hindsight, a laughable signpost of the Tech Bubble. Well, who’s laughing now?
