As for small-cap stocks, the Russell 2000 index gained 12% last year, compared to 27% for the large-cap S&P 500. Some analysts say that helps set the table for small-cap stocks to shine.

Small-cap stock valuations last month hit a 20-year low compared with large caps. And that leaves small-caps poised for stronger gains over the next decade than large caps, according to Bank of America.

The forward price-earnings multiple of the Russell 2000 totaled 0.75 times that of the Russell 1000 predominantly large-cap index in December, Bank of America equity strategist Jill Carey Hall said in a commentary Wednesday.

That’s more than 25% below the long-term average of 1.02 times and the cheapest since 2001, she noted.

Just as the “2000s were a strong decade for small-caps despite what was ultimately a negative decade for large-caps, … the Russell 2000 could see high-single-digit annualized returns over the next decade versus low-single-digit annualized returns for the Russell 1000,” Hall said.
