Equity markets don't stand still: the case for diversification

Large-cap growth has been difficult to ignore, delivering strong performance over the last few years. But the equity quilt below reminds us that no segment stays on top indefinitely. History shows that periods of narrow market leadership are often followed by broader participation. What leads one year can quickly give way to another the next year.

For example, year-to-date, we see small-cap and emerging market equities moving back toward the top following a period of relative underperformance. Maintaining exposure across styles, market capitalizations, and regions can help investors capture a broader range of return opportunities over time.

Staying invested: After the worst day, the best day may come quickly

The S&P 500’s worst day and the best day that followed have something in common: you can’t predict either one. The table below underscores the risk of stepping out of the market during periods of heightened volatility. While selling after a sharp decline may feel like a way to avoid further losses, some of the market’s biggest gains have historically occurred soon after its biggest drops. For example, in 2020 and 2025, the S&P 500’s best day after the year’s worst came just six and three trading days later, respectively.
