SET Index (Thailand) Index — Level, Chart & Constituents

What the SET Index (Thailand) measures

The SET Index (Thailand) is a stock market index that tracks the performance of the listed companies on the Stock Exchange of Thailand. It is a broad-market, capitalization-weighted index, meaning that larger companies have a greater influence on its movements. As a key barometer of the Thai equity market, it belongs to the Asia-Pacific sector and is part of the S&P/ASX 200 peer group of regional benchmarks. Investors use it to gauge the overall direction of Thai equities and to compare the performance of their own portfolios against the local market.

Key numbers explained

• The current index level of 1,607.63 points represents the aggregate value of all included stocks, calculated using the current prices and their respective weights.
• Today's low and high of 1,603.46 and 1,613.45 show the price range the index traded within during the session, indicating its intraday volatility.
• The price change today of +0.32% reflects the percentage gain or loss from the previous close, a standard way to express short-term movement.
• The 52-week low and high of 1,507.22 and 1,695.99 mark the lowest and highest levels the index has reached over the past year, providing a longer-term context for its current valuation.
• The index is denominated in THB, the Thai Baht, so its level is expressed in local currency and is not directly comparable to indices quoted in other currencies.
• The price-to-earnings ratio (P/E ratio) is a common valuation metric derived from the index's components; a higher P/E ratio generally suggests the market expects higher future earnings growth.
• The dividend yield measures the annual dividend income relative to the index level, offering a sense of the income return investors might expect from the underlying stocks.

What to watch

The SET Index (Thailand) is influenced by a range of general factors that affect equity markets. Domestic economic data, such as GDP growth and consumer spending, can drive corporate earnings expectations. Monetary policy decisions by the Bank of Thailand, including interest rate changes, affect borrowing costs and investment flows. Global risk sentiment, commodity prices, and currency movements of the Thai Baht also play a role. Political developments and regulatory changes in Thailand can impact investor confidence. For a more focused view, the SET50 tracks the 50 largest stocks, which often move in tandem with the broader index. Regional peers like the Straits Times Index (STI), Nifty 50, BSE Sensex, TAIEX (Taiwan Capitalization Weighted), Hang Seng TECH Index, and S&P/ASX 200 offer a comparative perspective on Asia-Pacific market trends.
