The iShares Morningstar Small-Cap Growth ETF (ISCG) was launched on June 28, 2004, and is a passively managed exchange traded fund designed to offer broad exposure to the Small Cap Growth segment of the US equity market.
The fund is sponsored by Blackrock. It has amassed assets over $763.25 million, making it one of the average sized ETFs attempting to match the Small Cap Growth segment of the US equity market.
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.
Growth stocks have higher than average sales and earnings growth rates. While these are expected to grow faster than the broader market, they also have higher valuations. Something to keep in mind is the higher level of volatility that is affiliated with growth stocks. They are likely to outperform value stocks in strong bull markets but over the longer-term, value stocks have delivered better returns than growth stocks in almost all markets.
Costs
When considering an ETF's total return, expense ratios are an important factor, and cheaper funds can significantly outperform their more expensive counterparts in the long term if all other factors remain equal.
Annual operating expenses for this ETF are 0.06%, making it the least expensive products in the space.
It has a 12-month trailing dividend yield of 0.8%.
Sector Exposure and Top Holdings
Even though ETFs offer diversified exposure which minimizes single stock risk, it is still important to look into a fund's holdings before investing. Luckily, most ETFs are very transparent products that disclose their holdings on a daily basis.
