Equal Weighted Indexes

[ˈiːkwəl ˈweɪ.tɪd ˈɪn.deks]

Equal-weighted indexes are stock market indexes that give equal weight to each stock in the index, regardless of the size of the company or the market capitalization of the stock. 

What are Equal Weighted Indexes (EWI)?

Equal-weighted indexes are a type of stock market index that assigns equal importance to each stock in the index, without regard to the size of the company or its market capitalization. This is different from traditional market-capitalization-weighted indexes, which give a higher weight to larger companies with higher market capitalizations.

Equal-weighted indexes are designed to provide a more diversified representation of the market, with a focus on small-cap stocks. By giving equal weight to each stock, the index may also have a higher concentration of growth stocks and a lower concentration of value stocks compared to traditional market-cap-weighted indexes.

Equal-weighted indexes can be useful for investors who want exposure to a broad range of stocks, including smaller companies, without being dominated by the largest stocks in the index. However, they may also be subject to higher turnover and transaction costs than market-cap-weighted indexes.

Key Takeaways

• All stocks have the same weight: In an equal-weighted index, each stock in the index is given the same weight, regardless of the company's size or market capitalization.
• More diversified: EWI can provide a more diversified representation of the market, including a higher concentration of small-cap stocks.
• Higher exposure to growth stocks: An equal-weighted index may have a higher concentration of growth stocks compared to traditional market-cap-weighted indexes.
• Lower concentration of large-cap stocks: EWI provide a lower concentration of large-cap stocks, which may be appealing to investors looking for exposure to a wider range of companies.
• Higher turnover and transaction costs: Because the index assigns the same weight to each stock, it may require more frequent rebalancing and have higher turnover and transaction costs compared to market-cap-weighted indexes.

Example

1. The S&P 500 Equal Weight Index: This index provides an equal weight to each of the 500 stocks in the S&P 500 index, rather than the market capitalization weightings used in the traditional S&P 500 index.
2. The Dow Jones U.S. Equal Weight Index: This index provides an equal weight to each stock in the Dow Jones U.S. Total Stock Market Index, which includes all U.S.-based companies with readily available stock price data.
3. The MSCI USA Equal Weighted Index: This index tracks the performance of large and mid-cap U.S. stocks and provides equal weight to each of the stocks in the index.
