Changing behaviour, IT hit retail investors' valueThe proportion of retail investors in total market trading value has dwindled by half amid changes in investor behaviour and the advent of high-speed algorithmic trading programs. Both algorithmic trading and high-frequency trading programs are accounting for more than 20% of total market trading value on a daily basis, Mr Montree said. The ratio is a significant increase from the past, while the proportion of retail investors' trading value has declined to around 30% from 60% previously, he said. "Thailand's stock market has a different characteristic from its regional counterparts because we used to have retail investors leading total market trading valuation," Mr Montree said. First, retail investors' behaviour has changed from the past because they have been exposed to investment strategies designed for better returns.
