Fund Details
Investment Thesis
Small-cap stocks have historically outperformed large-caps over long periods while providing genuine diversification benefits. IWM tracks 2,000 smaller US companies that collectively represent the domestic-facing US economy, more sensitive to US GDP growth and consumer spending than multinational mega-caps. Small-cap valuations are most attractive following periods of large-cap outperformance.
Who It's For
Investors bullish on US domestic economic growth and those seeking portfolio diversification beyond mega-cap technology. IWM is a popular vehicle for tactical small-cap rotation when valuations favor smaller companies relative to large-caps. Suitable for long-term investors as a diversifying complement to S&P 500 core holdings and for active traders seeking domestically-sensitive equity exposure.
