The article talks about a study that found that stocks have some kind of inertia, i.e. the best stocks in a given year probably will be good performers in the next year.
That is one of the most stupid ideas I ever read, so it should be propagated.

"Surprisingly, it was found that the losers portfolio consistently beat the market index, while the winners portfolio consistently underperformed. In total, the cumulative difference between the two portfolios was almost 25% during the three-year time span. In other words, it appears that the original "winners" would became "losers", and vice versa"
But I really agree that we should propagate any stupid ideas!
