Consumer discretionary stocks account for the biggest portion of the portfolio but still make up less than 25% of the index. Technology and industrial stocks are the next biggest sectors represented in the ETF.
The nature of the smaller companies in the index leads to greater turnover, but management keeps turnover relatively low for a mid-cap growth index fund. If you want to diversify away from the big tech names that dominate growth stocks, the iShares Russell Mid-Cap Growth ETF is a good option.
4. Vanguard Small-Cap Growth ETF
Small-cap growth stocks offer the biggest potential for capital appreciation. Since they're small companies, it takes relatively little increased buying interest to move the stocks significantly higher. The Vanguard Small-Cap Growth ETF offers a simple way to gain exposure to this sector without having to dig for individual stocks.
