The T. Rowe Price Small-Mid Cap ETF (TMSL) charges only 55 basis points (BPS) to actively invest in small and mid-cap equities. The active ETF will hit its three-year anniversary milestone next June, likely putting the growing ETF on even more investors’ radar.

Specifically, its managers take a bottom-up stock selection approach, assessing companies for fundamental metrics like profitability, stability, earnings quality, return on equity, book value and more. Together, that has helped the fund return 5.6% YTD, beating its Factset Segment average in that time. Which rising small- cap stocks, then, have been starring in the ETF’s portfolio?
