Markets exhibited significant volatility in March following the escalation of geopolitical tensions in late February. Equity markets struggled to find direction, and headlines grew more urgent. Inside defined contribution plans, however, the response was far more measured. While some 401(k) plan participants made adjustments, the majority stayed the course, according to the Alight Solutions 401(k) Index™. Overall behavior remained steady and notably disciplined during a period that could have easily triggered more reactive decision-making.
Trading activity rises, but stays in check
Trading picked up modestly in March, with three above-normal trading days. Even so, activity remained well within typical ranges. Total transfers for the quarter equaled just 0.50% of starting balances, hardly a sign of panic.
When participants did act, they tended to lean more defensive. Nearly three-quarters of March trading days favored fixed income, suggesting a short-term move toward stability as markets absorbed geopolitical and economic uncertainty.
At the same time, market pullbacks appear to have created selective opportunities. Periods of declining prices can benefit long-term investors who continue contributing, allowing them to buy assets at lower valuations. They may also prompt rebalancing as portfolios drift from target allocations. The data suggests some participants responded in this way, making targeted adjustments rather than stepping away from the market entirely.
A shift toward stability with continued interest in growth
Overall flows in the first quarter reflected a nuanced approach. After leaning more conservative throughout much of 2025, participants favored emerging markets and international funds in January and February. In March, however, fixed income investments, including money market, stable value and bond funds captured 54% of inflows, signaling a renewed emphasis on stability.
Outflows were concentrated in large U.S. equity funds (72%) and company stock (17%). Rather than broad-based selling, this pattern points to selective repositioning as participants adjusted exposures in response to market conditions.
Long-term strategy remains intact
Despite the increased activity in March, portfolios changed very little overall. Average equity exposure edged down only slightly, ending the month at 72.8%. Contributions remained steady as well, with 71% directed to equities, reinforcing that participants continued to invest throughout the downturn.
Target date funds remained the anchor of participant portfolios, representing nearly one-third of total balances and close to half of all contributions.
In short, even during a volatile month, most savers maintained their long-term approach.
A familiar response to uncertainty
The first quarter brought no shortage of challenges: geopolitical conflict, uneven markets and ongoing economic questions. Yet participant behavior followed a now-familiar pattern.
Rather than reacting sharply, investors adjusted incrementally. They added stability where needed, maintained growth exposure and kept contributions flowing. Increasingly, volatility appears to be viewed as part of the investing cycle rather than a signal to abandon strategy altogether.
What it means for plan sponsors
For plan sponsors, the first quarter offers a clear takeaway: participants are handling volatility better than they have in the past.
Even with increased trading in March, behavior remained measured. Most participants made targeted adjustments while maintaining long-term allocations and contribution rates. That reflects the cumulative impact of stronger plan design, diversified default options and more effective participant communication.
It also reinforces the importance of a well-rounded investment lineup. Fixed income options provided stability during a volatile stretch, while access to international and emerging market funds allowed participants to reposition as valuations shifted. Just as important, steady contributions during market dips can help participants benefit from lower prices over time and naturally rebalance portfolios without drastic action.
In environments like this, the sponsor's role is less about reacting and more about reinforcing perspective. Clear communication around long-term investing, diversification and staying invested can help participants keep their focus when markets get noisy.
The bottom line: when plans are designed thoughtfully and supported with the right tools, even a volatile month like March can become less of a disruption—and more of an opportunity.
