Columbia Research Enhanced Core ETF (the Fund) seeks investment results that, before fees and expenses, closely correspond to the performance of the Beta Advantage Research Enhanced U.S. Equity Index (the Index).
The fund tracks the Beta Advantage Research Enhanced U.S. Equity Index, a rules-based subset of the Russell 1000 that applies quality, value, and catalyst screens to select approximately 325–400 holdings, rebalanced semi-annually. The fund invests in substantially all Index securities in the same proportions, though it may sample holdings or adjust weightings when replication is impracticable. Because the Index applies no sector constraints, the fund's sector exposure mirrors the Index's concentration, which as of October 2025 was heavily weighted to information technology.

How it has done
RECS share class · total returns with dividends reinvested
Volatility over the last 12 months: 11.17%. Past returns are a record, not a forecast.
Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
