The Stock Exchange of Thailand, also known as SET, is the national stock exchange of Thailand and it is located in Bangkok, the capital of Thailand. The indices of the SET are SET index, SET 50 Index and SET 100 Index.

The Thailand stock market has its origins in the early 1960s when the first five year National Economic and Social Development Plant was implemented to promote the economic growth and to develop the country’s standard of living. After this, the Second National Economic and Social Development Plan proposed to establish an organized securities market to get additional capital for national economic development.

This saw the creation of the first officially sanctioned and regulated securities market and it most important role was to mobilize funds to help further Thailand’s industrialization and economic development.

Thailand’s capital market in saw two phases. The first phase was the Bangkok Stock Exchange, a privately owned exchange; and the second phase saw the establishment of the The Securities Exchange of Thailand or SET.

A legislation was formally enacted in 1974 to establish the The Securities Exchange of Thailand and the SET started trading from April 30, 1975. The Securities Exchange of Thailand officially changed its name to The Stock Exchange of Thailand (SET) on January 1, 1991.

Since April 1991, The Stock Exchange of Thailand, or SET, has been operating fully computerized trading so that the Thailand stock market is efficient, equitable and fluid. In this computerized trading, two methods of trading are primarily available and these are Automatic Order Matching (AOM) and Put Through Transactions (PT).

The SET works on all bank business days which are usually from Monday through Friday. There are two trading sessions in a day. The first trading session is in the morning from 10.00 a.m. to 12.30 p.m., and the second trading session is in the afternoon from 2.30 p.m. to 4.30 p.m.
