The performance of Thai stocks this year has reflected the broader problems of the economy, one of the weakest in Asia.

Tariffs, slowdown in tourism, rise in the baht and weakness in investment and industrial sentiment have all weighed on the market.

Foreign investors ended the year as net sellers of 107.06 billion baht worth of Thai stocks, compared to 146.9 billion baht in 2024.

Local individuals were net buyers worth 158.64 billion baht, compared to 98.1 billion.

Local institutions were net sellers worth 38 billion baht, compared to 48.2 million baht the previous year.

Proprietary trading (brokers) recorded a net selling position of 13.6 billion bahts, compared to 22.8 billion in 2024.

The average daily turnover on the SET as of November 30 was 41.91 billion bahts, compared to 46.55 billion at the end of 2024.

The SET index reached its highest level at 1,395.70 during the first week of January and its lowest level at 1,053.79 on June 22.

The combined market capitalization of the SET and the alternative investment market fell to around 13,400 billion bahts as of December 29, compared to 16,500 billion at the end of the previous year.

In one year, nearly 3,100 billion bahts in value has thus evaporated from the Thai market.
