FBM KLCI
FBM KLCI explained: the 30 largest Main Market companies, free-float market value weighting, and how Malaysian investors use it. Market data is end-of-day.
What is FBM KLCI?
The FBM KLCI, short for FTSE Bursa Malaysia KLCI, is a benchmark index of the 30 largest companies on Bursa Malaysia’s Main Market. Each constituent is weighted by free-float market value, and the constituent list is reviewed periodically. Investors use it to gauge the broad direction of large Malaysian stocks.
How it is calculated
The index is weighted by free-float market value. Each company’s weight equals its free-float market value divided by the total for all constituents. Free-float market value is the share price multiplied by shares available for public trading, excluding large strategic holdings. A day’s index move is broadly the weighted average of its constituents’ moves.
How Malaysian investors use it
Investors use the FBM KLCI as a benchmark. If a portfolio rose 5% while the index rose 8%, the portfolio lagged the market over that period. Because the index is weighted toward larger companies, it may not reflect smaller counters on the ACE Market, which can move differently.
Worked example: Company A
Hypothetical figures: the 30 constituents have total free-float value of RM400 billion, and Company A has RM8 billion of it.
- Company A’s weight = 8 divided by 400 = 2%.
- If Company A rises 5% on a day, its contribution is about 2% × 5% = 0.1 percentage points to the index move, all else equal.
Common mistakes
- Assuming the index covers the whole Bursa market. It tracks 30 Main Market companies.
- Comparing a small or sector-specific portfolio with the index without allowing for differences.
- Reading one day’s index move as a signal on its own.

Does a rising index mean my holdings will rise?

Is the FBM KLCI the same as the whole Bursa market?
No. It covers 30 large Main Market companies, so smaller counters can move differently.
