The strategy works like this:
-
1) Of the stocks that currently make up the Dow Jones Industrial Average, sort them by dividend yield and select the 10 highest yielding ones.

I tried to get some definitive statistics on the performance of these Beating the Dow strategies, but I got the total feeling that depending on who was doing the research depended on what the results looked like. Some sources were incredibly upbeat about its performance while others went off on how all this strategy is is a data mining exercise and should not be considered an effective strategy.

With that, at least you have not left everything to chance and can take some ownership in your decisions.
P.S. If these screens really interest you, then a good site to check out is Dogs of the Dow .
[...] There are a lot of different mechanical investing strategies out there. I would suggest that the most popular of these strategies is one I have written about before - Dogs of the Dow. There are also a couple that have been created by the guru of mechanical investing, James O’Shaughnessy. O’Shaughnessy has written a couple of books on the subject, most notable of which are What Works on Wall Street and How to Retire Rich. Again, the impetus behinds all of these strategies is removing the negative impacts of emotional decisions on investing performance. [...]
