BlackRock will pay final distributions (or dividends) for 2025 on many of its ASX exchange-traded funds (ETFs) on Monday.
Those ETFs include iShares Core S&P/ASX 200 ETF (ASX: IOZ) and iShares S&P/ASX Small Ordinaries ETF (ASX: ISO).
IOZ ETF delivered a solid 10.36% return for 2025 in line with the strength of the benchmark S&P/ASX 200 Index (ASX: XJO) last year.
The ISO ETF outperformed, producing a 24.54% total return as ASX small-cap shares benefitted from three interest rate cuts.
Small-caps have market valuations of between a few hundred million dollars and $2 billion, and carry more debt to fund their growth.
Perpetual portfolio manager Alex Patten said 2025 represented the first time that small-caps had outperformed "in a number of years".
Patten said:
… now that rates are starting to come down, we're seeing more interest in small and micro caps and bit more liquidity in the market.
