Straits Times Index
Encyclopedia : S : ST : STR : Straits Times Index
The Straits Times Index (STI) is a market value-weighted stock market index based on the stocks of 50 representative companies listed on the Singapore Exchange.
Launched in the wake of a major sectoral re-classification of listed companies by the Singapore Exchange, which saw the removal of the "industrials" category, the STI replaced the Straits Times Industrials Index (STII), and began trading 1 September 1998 at 885.26 points, in continuation of where the STII left off. Then, it represented 78% of the average daily traded value over a 12-month period and 61.2% of total market capitalisation on the exchange.
Constructed by the Singapore Press Holdings, the Singapore Exchange and Professor Tse Yiu Kuen from the Singapore Management University, it comes under formal review at least once annually, and may also be reviewed on an ad-hoc basis when necessary. One such review, for instance, raised the number of stocks from 45 to 50, which took effect when trading resumed on 18 March 2005. This change reduced the index representation of the average daily traded value to 60%, while increasing its total market capitalisation to 75%.
