SET Opens for a Hearing for SET50-SET100 Calculation to “Free Float Adjusted Market Cap”

The Stock Exchange of Thailand (SET) has opened for a hearing on the adjustment method for calculating the SET Index during the period of 2H21 from the Market Capitalization method, to Free Float Adjusted Market Capitalization, allowing the index to have a better reflection on the on-going situation in the market and in line with the global standard.


Moreover, the SET is expected to adjust the free float for the calculation of SET50, SET100 , SETCLMV, SETHD, SETTHSI and SETWB on the semi-annual rebalancing in June and December. Meanwhile, the free float used to calculate the index is expected to be adjusted to 1%.


Asia Wealth Securities (AWS) stated that the adjustment will affect large-cap stocks with low free float as the groups expected to suffer the most are the energy and transportation sectors. These include stocks such as DELTA, AOT, OR PTTEP, GPSC, AWC, GULF, BJC and SCGP, while benefiting groups will be banking, hospital and retail which are BBL, SCC KBANK, BCMS, CPALL, INTUCH, TISCO and CPN.
