Alight Solutions 401(k) IndexTM: April 2026 Observations

Alight Solutions 401(k) IndexTM: February 2026 observations

Trading activity continued to accelerate in April, with four days of above‑normal1 trading volume. What’s more, the S&P 500 posted a double‑digit gain for the month, only the 13th time this has occurred in the past century.

April largely unfolded in two distinct phases. Over the first 12 trading days, $74.5 million moved from fixed income into equities. In the final nine trading days, $212 million flowed in the opposite direction, from equities back into fixed funds, as some participants took profits and locked in gains.

The majority of participants, however, remained invested throughout April. That discipline proved beneficial, as broad market returns continued to build over the course of the month. In March, participants generally stayed committed to their long‑term allocations, despite geopolitical uncertainty and market volatility, an approach that was rewarded in April.

April observations:

  • On average, 0.012% of 401(k) balances were traded daily.
  • 13 of 21 days favored fixed income funds.
