Factors Affecting Performance [Text Block]

What drove fund performance during the past 12 months?

  • Global stock indexes and fixed income markets were broadly positive for the 12 months ended May 31, 2025. Many major central banks began easing interest rates early in the period as inflation slowed. Early optimism over the U.S. election of President Donald Trump brought, first, a boost to U.S. equities, followed by heightened volatility in global equity markets amid concerns over Trump’s fluctuating tariff policies.

  • Versus the style-specific S&P Target Date 2010 Index, exposure to short duration Treasury inflation protected securities contributed to performance for the trailing one-year period. Additionally, our diversified U.S. mid-cap equity structure added value as our dedicated allocations to growth and value outpaced the benchmark’s core-oriented mid-cap equity allocation.

  • On the negative side, a leading detractor from relative results was security selection within the US Mid-Cap Growth Equity Strategy, which trailed its benchmark. The fund’s smaller allocation to U.S. large-cap equities versus small- and mid-cap equities compared with the benchmark also detracted.

  • The fund seeks the highest total return over time, consistent with an emphasis on both capital growth and income. The fund invests in a diversified portfolio of other T. Rowe Price stock and bond mutual funds that represent various asset classes and sectors. Its allocation among T. Rowe Price funds will change over time in relation to its target retirement date.
