qqew. edit: comment from Carl Swenlin:

"In the end I prefer equal-weighted indexes because they perform much better than their cap-weighted alternatives. For example, the Nasdaq 100 advanced 114% from the October 2002 bear market low to the recent highs. During the same period our unweighted Nasdaq 100 Index advanced 178%.

The secret behind this superior performance has to do with the fact that the smaller-cap stocks in an index usually perform better than the large-cap stocks; however, one should always be aware of the changing relative strength between the unweighted index and its cap-weighted version. Bear markets usually cause small-cap stocks to under perform large-cap stocks, so equal weight indexes may be more dangerous than the cap-weighted alternatives."
