Key Takeaways

Highlights
- Bursa and FTSE Russell jointly announced yesterday plans to widen the
number of constituents for the FBMKLCI index from 30 to 50 constituents,
creating a more sectorially diverse and economically representative index.
- Concurrently, the FBM70 will be reduced from 70 to 50 constituents and
renamed the FTSE Bursa Malaysia Mid Cap Index from 21 Dec 26, while the
FBM100 will remain unchanged.
- Implementation will occur in two phases to facilitate orderly portfolio
rebalancing and minimise concentrated trading flows and market impact.
- Our impact assessment suggests only modest impact from Malaysian equity
index-linked portfolio fund outflows (negatively impacting incumbent index
components) and inflows (positively impacting new entrants).
Analysis
- No dramatic impact is expected. While some sector weightings could fall
should FBM50 replace FBMKLCI as Malaysia’s equity index benchmark (ie,
financials), we estimate that only about US$1b of passive/index funds
(representing about 5% of the estimated passive funds invested in Malaysian
equities) directly track the FBMKLCI (Bloomberg data suggests that the index
equity funds predominantly track MSCI indices).
- Sector weighting impact. Based on a simulation using market data as at 20
Aug 26 (see overleaf chart and table), the weighting of financial stocks could
fall to 39.4% (from Phase 1 implementation) and 36.5% (upon Phase 2
implementation) from 42.7%, while utilities may decline to 13.7% (upon
Phase 2 implementation) from 16.7%. Among the existing KLCI sectors,
construction and consumer could gain the most with their weightages rising
from 3.7% and 2.6% respectively to 4.8% and 3.6% respectively. Otherwise,
technology would be the biggest winner of the new additions, commanding
an estimated 3.4% weightage in the expanded index.
- Sector losers. Sector-wise, losers are banking (-6.2ppts), utilities (-3.0ppts)
and manufacturing (-0.5ppts), potentially prompting passive funds to dilute
existing positions.
- Modest stock losers. Listed Petronas subsidiaries, Maybank and Axiata
would see the most downside as the new additions would dilute their
weightage by an estimated 1-3ppts. However, downside is marginal at only
0.2%-0.3% of their respective market capitalisation, based on the assumption
that only about US$1b worth of passive funds are linked to the FBMKLCI.
- Sector winners. Sectorial representation will widen from 11 sectors to 16 as
technology (3.4% weightage), automobiles (1.3%), REITs (1.2%), ports
(0.9%), and gaming (0.4%) are included (refer to pie chart below). Besides
this, other noteworthy sectors which are currently represented in the
FBMKLCI index include construction, consumer and property.
- Stock inclusion winners. Noteworthy additions include Westports, Hong
Leong Financial Group, United Plantations, KLCCP Stapled Group as well
as the large-cap technology names (eg. Vitrox, MPI, Frontken, Inari) which
will gain benchmark representation and could attract passive fund inflows
from FBMKLCI-linked funds. Meanwhile, the phased inclusion – 50% in Dec
26 and the remainder in Jun 27 – should create two rounds of buying and
improve liquidity, institutional visibility and valuation discovery.
