Stock in FBM30 but not in KLCI in favor : Resorts, YTL, Parkson ...
The drop outs may not in favor : Gamuda, SP Setia ...
Bear in mind one of the fundamental fund manager portfolios is usually an index fund. And they are benchmarking their fund performance with country's index ie. KLCI in the past. Changing the country's index components means the fund managers may have to change their strategy too.
Generally this is good news .... to general public especially mutual fund investors. What will happen in short term is the not-so-good index fund will drop significantly but eventually all index fund are performing quite the same ....
