Most investors have probably heard of the Dogs of the Dow strategy. Rank the dividend-yielding Dow Jones Industrial Average stocks from highest to lowest yield and buy the top 10. Hold for one year and a day and sell. Then do it all over again.

This strategy was all the rage back in the early 1990s, and for good reason. The strategy had a market-beating track record and only required about an hour per year to pick the stocks. However, the strategy faltered when the market went nuts in the late 1990s, causing investors to lose interest. 

As of Dec. 31, 2009, the Dogs of the Dow strategy has produced annual returns of 9%, 3.2%, and 1.1% over the past 15 years, 10 years, and five years, respectively.

There have been many takes on this strategy: Small Dogs of the Dow, Dow Underdogs, and Dogs of CAPS among others. For a time, the Motley Fool even had a strategy named the Foolish Four, however it was abandoned in 2000 after "more extensive long-term studies completed by our staff show that the strategy hasn't beaten the market by as much as it did in our original 25-year sample. Over the past 50 years, Foolish Four outperformance was less than 2% annually. While still attractive, the approach is suspect in light of the recent changes in the Dow. The addition of non-dividend paying companies and a waning interest in dividend income have caused us to doubt that the strategy will consistently outperform the stock market's average in the future."

Dogs of the S&P 500
With that said, what if we applied this to the S&P 500, an index of 500 stocks compiled by Standard & Poor's that includes "leading companies in leading industries of the U.S. economy, capturing 75% coverage of U.S. equities." While the S&P 500 also has some non-dividend paying stocks, 372 (74.4%) of the companies in the index pay dividends.

I don't advocate mechanical investing, but some of these are definitely worth a further look. For example, Altria was recently singled out as "Probably the World's Greatest Investment" by Fool wunderkind Morgan Housel.
