Barclays Readies 10 New iShares Exchange-Traded Funds

Like Woody Allen movies and Stephen King tomes, new iShares exchange-traded funds from Barclays Global Investors continue to roll out at a surprising pace.

On Friday, 10 more iShares funds will launch, bringing the firm's iShares fund total to 56. Since introducing iShares in May, the funds have gathered $2.6 billion in assets.

Exchange-traded funds, or ETFs, are baskets of stocks that typically replicate an index and trade as one security on a stock exchange. Many believe they pose a serious threat to traditional open-end mutual funds because they typically offer lower costs and the convenience of intraday pricing and trading. Although the value of a traditional mutual funds portfolio changes constantly throughout the day, mutual funds typically only price at the end of the trading day. (Want to know more about ETFs?

The latest batch gives investors the opportunity to focus on different-size U.S. stocks in the growth or value style, in addition to European equities. Small-caps are typically defined as companies with a market capitalization below 1.5 billion. Mid-caps usually have a market cap between $1.5 billion and $12 billion. Value stocks are typically less flashy stocks with lower price-to-earnings , or P/E, ratios. Growth stocks are often growing at a quick pace and sport higher P/E multiples.

Below is a list of the rookies along with their tickers and expenses. Each will trade on the American Stock Exchange .

The average U.S. stock fund's expense ratio is 1.4%, according to Morningstar. The average European-focused stock fund carries a 1.74% expense ratio.
