The 4-day fair expects to draw over 100,000 visitors.
Stock Exchange of Thailand President Charamporn Jotikasthira said that due to cooperation in boosting financial literacy, the stock market welcomed 90,000 new investors in the first nine months of this year.
He is confident that the number would rise further next year.
In previous fairs, 60 per cent of the visitors never had investment in the stock market and came to seek advice from financial experts.
