Value investing is a popular long-term investment strategy. Value stocks have historically outperformed growth stocks, or companies with high earnings expectations, in almost every market over the long-haul. For instance, the MSCI USA Value Index has outperformed the MSCI USA Growth Index by an annualized 81 basis points since 1974 through September 2015.

VLUE “seeks to track the performance of an index that measures the performance of U.S. large- and mid-capitalization stocks with value characteristics and relatively lower valuations, before fees and expenses,” according to iShares.

The ETF allocates over 37% of its weight to technology and financial services stocks with another 26.6% going to healthcare and consumer discretionary names. Seven of VLUE’s top 10 holdings are members of the Dow Jones Industrial Average, including Apple (NasdaqGS: AAPL), Pfizer (NYSE: PFE) and Chevron (NYSE: CVX).

VLUE “uses the value factor by investing in large- and mid-cap stocks in the United States whose fundamentals make them undervalued compared to other stocks. Those fundamentals include three ratios: price-to-book, price-to-forward earnings and enterprise value-to-cash flow from operations,” according to Investopedia.
