The Thai stock market is preparing for a significant wave of volatility as the latest MSCI Global Standard Index rebalancing is set to take effect at the closing bell on May 29. According to market estimates, the reweighting is expected to trigger a total outflow of approximately ฿8,600 million from Thai equities.

Electronic components giant DELTA is expected to see the largest boost, with an estimated inflow of ฿1,500 million. Energy major PTT follows with a projected ฿570 million in new capital. Other notable gainers include:

- CPN: +฿200 million
- Banking Sector: KBANK (+฿185M), KTB (+฿180M), and SCB (+฿180M) are all slated for modest increases.
The “outflow” list is dominated by heavyweights in the energy, telecommunications, and transport sectors. GULF is anticipated to face the most significant selling pressure, with an estimated outflow of ฿3,000 million. PTTEP and ADVANC are also high on the list, with projected outflows of ฿2,000 million and ฿1,500 million, respectively. Other stocks facing weight reductions include:
