There is an equal-weighted S&P 500 ETF: RSP.
I just googled a Scott Burns article about this subject. Excerpt:
The limitation of an equal-weighted index fund, Mr. Arnott points out, is that it's a lot more difficult to buy or sell the smallest stock in the index than the largest stock. Basically, it's difficult to scale-up an equal-weighted index fund. In addition, transaction costs are likely to be much larger.
Mr. Arnott proposes what he calls "fundamental" or "Main Street" indexation. Rather than sorting stocks by market capitalization -- a favorite Wall Street measure -- he proposes building portfolios based on fundamental measures: book value, trailing five-year average operating income, trailing five-year average revenue, trailing five-year average sales, trailing five-year average gross dividend or total employment. In addition, he constructed a composite portfolio combining several of these measures.
The result?
Over the 42-year period from 1962 to 2003, the S&P 500 index returned 10.52 percent annually. A capitalization-weighted index of 1,000 stocks returned slightly less, 10.30 percent. But the Main Street-indexed portfolios returned an average of 12.43 percent. Main Street indexing, in other words, beat capitalization-weighted indexing of the same stocks by an average of 2.13 percent annually while beating the S&P 500 index by 1.91 percent annually.
What causes the difference?
Mr. Arnott believes that capitalization-weighted indexes systematically overexpose stocks that are overvalued while underexposing stocks that are undervalued. An equal-weighted index, like the Rydex ETF mentioned earlier, overcomes this systematic performance drag by eliminating capitalization weighting. Using any of the Main Street index-building tools, however, overcomes the systematic performance drag while allowing the construction of more liquid portfolios.
