Why Small Cap Growth

Small cap companies have market capitalization below $2 billion. They usually have higher potential than large and mid cap companies with stocks but higher risk.

While growth stocks do boast higher than average sales and earnings growth rates, and they are expected to grow faster than the wider market, investors should note these kinds of stocks have higher valuations. Additionally, growth stocks have a greater level of risk associated with them. Compared to value stocks, growth stocks are a safer bet in a strong bull market, but don't perform as strongly in almost all other financial environments.

Costs

Expense ratios are an important factor in the return of an ETF and in the long term, cheaper funds can significantly outperform their more expensive counterparts, other things remaining the same.

Annual operating expenses for this ETF are 0.3%, putting it on par with most peer products in the space.

It has a 12-month trailing dividend yield of 0.33%.

Sector Exposure and Top Holdings

ETFs offer a diversified exposure and thus minimize single stock risk but it is still important to delve into a fund's holdings before investing. Most ETFs are very transparent products and many disclose their holdings on a daily basis.

This ETF has heaviest allocation to the Healthcare sector -- about 29% of the portfolio. Information Technology and Industrials round out the top three.

Looking at individual holdings, Cactus Inc. Class A (WHD) accounts for about 2.23% of total assets, followed by Trinet Group Inc. (TNET) and Ryman Hospitality Properties Inc. (RHP).

The top 10 holdings account for about 17.72% of total assets under management.
