Stocks in Thailand are traded on The Stock Exchange of Thailand (SET). In 1999 the SET established the Market for Alternative Investments (MAI), which is an exchange where small Thai companies can offer shares to the public.
Stocks on the MAI have smaller market capitalizations than those listed on the SET and are less established. Both exchanges offer stocks with volume and opportunity for global inventors. Before investing, traders should understand Thai stock regulations, the size of the market, major indexes, liquidity, Thai currency, as well as ways to domestically invest in Thailand.

Thai Stock Market: Operation and Risks
Thai trading hours are different than those in the U.S. Notably, there is an intermission that separates the trading day into a morning and afternoon session.
Figure 4 shows how the trading day operates.
During the Auction period, orders are collected and matched at one price based on supply and demand; this creates the Open and Close prices. Automatic Order Matching is equivalent to the U.S. markets, where bids and offers interact with each other for instant execution.
There are multiple order types available, including limit orders, market orders, market-to-limit order (market only to current bid or offer), at-open order (buy/sell on open) and at-close order (buy/ sell on close).
Shares are traded in board lots, which are 100 shares of a stock each. Stocks that consistently trade at a value above 500 baht can be traded in 50 share lots.
Spreads vary by the price of a security.
The risks associated with Thai stocks are those associated with any stock. Thailand is an emerging economy, offering stocks with great potential, but losses also occur. Trading stocks with high volume and large market capitalization provide some stability, although it won’t guarantee profitable trades.
Capital gains are tax-exempt (in Thailand) for individual investors; dividends are subject to a 10% withholding tax and interest income has 15% withholding tax .
Thai stocks are priced in Thai baht, so not only do investors need to concern themselves with the direction of the stock, but also the currency. A decline in the baht will have a dampening effect on returns once the stock is sold and the baht converted back to the U.S. dollars. An increasing Thai baht has a positive effect on returns.
Before investing or trading in a foreign market, it is important to understand how that market operates. Make small trades at first, until comfortable with the process and regulations. Once experienced, then move on to trading your typical position size.
Domestic Ways to Invest
There are a number of ways to invest in India stocks from within the U.S.
ETFs are traded on U.S. exchanges, priced in U.S. dollars and provide a basket of Thai stocks.
Another way to invest directly in Thai companies is through American Depositary Receipts (ADRs). These are foreign companies listed on U.S. exchanges, so they are accessible to investors and priced in U.S. dollars. Currently there are no ADRs listed on major U.S. exchanges such as the NYSE or Nasdaq, but 55 ADRs are available in the U.S. in the over-the-counter (OTC) market, which is less regulated than the major exchanges.

Sponsored ADRs are issued in participation with the foreign underlying company, whether as unsponsored ADRs are not.
The Bottom Line
Thailand is an emerging economy and while the size of the market remains small compared to the U.S. there are many stocks that provide significant volume and market capitalization to warrant foreign investment. Stocks are priced in Thai baht, and the exchange rate fluctuates, which could result in improved or reduced performance. Foreign investors can trade NVDRs with no restrictions but may face foreign ownership restrictions when attempting to buy regular stocks (if there is lots of foreign investment in those stocks already). ETFs and ADRs provide a way for investors to participate in the Thai market using U.S. exchanges and U.S. dollars.
