size=2>Erick,
Not
sure exactly what you mean. Do you wish to find the top 5% of the indexes or are
you looking for the top 5% of the stocks that comprise the indexes? In either
case first place your indexes (or stocks which comprise a given index) in a
watchlist then use percentile as your filter in the exploration . AB will return
those stocks/or indexes which pass the
percentile test
Regards,
Jayson
