The fourth quarter of 2025 saw U.S. equity markets influenced by a blend of optimism for monetary easing and cautious sentiments regarding economic growth and valuations.

During this period, value stocks outpaced growth stocks, according to Russell indices. The Meridian Small Cap Growth Fund recorded a net return of 0.90% in Q4 2025, slightly trailing the Russell 2000 Growth Index's 1.22% return.
