Capital Gains SZN Heats Up: What Investors Could Expect

Key takeaways

  • Capital gains distributions are higher in 2025 due to strong market returns.
  • Most equity categories expect increased distributions, especially growth and mid-cap segments.
  • Investors should assess tax exposure and redirect distributions to more tax-efficient solutions.

The year is winding down, but Cap Gains SZN is ramping up. It’s that time when the holidays bring together family, friends and shared traditions. There is a natural pause to reflect on the year’s accomplishments and lessons learned. It also marks the period when fund families start to calculate their net realized capital gains. For investors, “lessons learned” can take on a new meaning as they start to see what their tax bill could look like.

Around this time, most mutual fund and exchange-traded fund (ETF) providers release estimates of their upcoming distributions. We track and aggregate these early numbers to help you better prepare for what to expect. While the amounts won’t be final until distributions are officially announced and paid, with more than 75% of all funds having their estimates announced at this point, there is enough information to start assessing the broader picture.

Reflecting on 2025 market returns & historical distributions

Despite volatility early in the year, year-to-date market performance remains strong across the board. Focusing on equites, the Russell 3000 Index is up roughly 17.4% through the end of November, while international developed (MSCI EAFE Index) and emerging markets (MSCI EM Index) are up 24.5% and 29.5%, respectively, through the same time frame. So, the tradition of investors running into capital gains distributions is expected to continue and can potentially be a bit more widespread across asset classes given broader participation outside of U.S. equites.

As shown in the chart below, capital gains are distributed annually—typically during the month of December—and happen regardless of how markets perform. In strong market years, like this one, a tax bill alongside positive performance seems like a natural trade-off. Strong performance adds pressure, but it’s the investment activity within the funds that causes taxable distributions.

Having a highly appreciated portfolio—something that many investors may have experienced lately—makes it harder for managers to incorporate active management decisions without tapping gains. That challenge grows when investor preferences lead to outflows, which can pressure managers to sell positions they otherwise wouldn’t touch. This is also why capital gains may still occur in down years.
