Nevertheless the scarce data that I have been able to find does indicate that outperformance tends to persist, and that a portfolio of, say, the top performing 5% of stocks in the S&P 500 over the last five years would outperform the average over the next year.

S&P500, depends on starting date.
Nasdaq 100, yes, improved return.

This belongs in the MI board.
