AI Summary

The S&P 500 profit growth has accelerated to its fastest pace in nearly five years, driven in part by underperforming companies that have historically lagged behind their larger counterparts. These smaller companies, comprising nearly 99% of the index, have been steadily contributing to overall earnings growth. This shift is significant, as it marks a departure from the dominance of a select few companies that had driven growth in the past. The trend suggests that the broader market is gaining momentum, with smaller companies playing a more substantial role in driving earnings growth.
