The $100 Billion Swing Era | Managing Headline Overload

If you think capitalization swings are getting wider and more frequent, you may be right. By the end of October 2025, there were 119 instances of individual U.S. stocks (mainly large technology firms) moving by more than $100 billion in market cap in a single day this year, according to the International Business Times. In 2025, there were only 42 such instances, and in 2020 there were fewer than 10. These dramatic single-day moves have captured headlines and contributed to a sense that markets are becoming more unpredictable.

For retirement plan participants, these high-profile fluctuations can understandably raise questions and concerns about risk, diversification, and portfolio composition. Large swings in a handful of companies usually shouldn’t affect an individual’s long-horizon savings strategy or require short-term action. Clear communication can help participants understand how their investments are structured — and why a diversified, long-term strategy can continue to serve them well — and alleviate anxiety during periods of elevated volatility.
