The '''FTSE Straits Times Index''' ([[abbreviation]]: '''STI''') is a [[capitalization-weighted index|capitalisation-weighted]] [[stock market index]] that is regarded as the benchmark index for the stock market in [[Singapore]]. It tracks the performance of the top 30 companies that are listed on the [[Singapore Exchange]] (SGX). 

The STI is jointly calculated by the SGX, the [[SPH Media Trust]] and the [[FTSE Group]].<ref>{{cite news | title = Straits Times Index constituents unchanged after March review | publisher = [[The Straits Times]] | url = https://www.straitstimes.com/business/companies-markets/straits-times-index-constituents-unchanged-after-march-review | access-date = 16 February 2023}}</ref>

== History ==
===Early years===
The STI has a history dating back to its founding in 1966.<ref name="factsheet"/> Following a major sectoral re-classification of listed companies by the Singapore Exchange, which saw the removal of the "industrials" category, the STI replaced the previous '''Straits Times Industrials Index''' ([[abbreviation]]: '''STII''') and began trading on 31 August 1998 at 885.26 points, in continuation of where the STII left off. At the time, it represented 78% of the average daily traded value over a 12-month period and 61.2% of total [[market capitalisation]] on the exchange.<ref name="B">{{cite news | title = The STI Index | publisher = [[Business Times (Singapore)|The Business Times]] | url = http://www.businesstimes.com.sg/mnt/html/stindex/stintro/stiIntro.html | access-date = 28 February 2011 | archive-url = https://web.archive.org/web/20110723183532/http://www.businesstimes.com.sg/mnt/html/stindex/stintro/stiIntro.html | archive-date = 23 July 2011 | url-status = dead }}</ref> 

The STI was constructed by SPH, the Singapore Exchange and SPH's consultant, Professor Tse Yiu Kuen from the [[Singapore Management University]] (formerly from the [[National University of Singapore]]). It came under formal review at least once annually and was also reviewed on an ''ad hoc'' basis when necessary.<ref name="B" /> 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%.{{Citation needed|date=February 2011}}

===Revamp===
The STI was again revamped and relaunched on 10 January 2008. As part of a new partnership between SPH, SGX and FTSE, the number of constituent stocks was reduced from about 50 to 30 and the index was re-calculated using FTSE's methodology.<ref>{{cite web |title=SPH, SGX and FTSE launch revamped Straits Times Index and new FTSE ST Index Series today |url=http://www.straitstimes.com/FTSE%2BST%2BIndex%2BSeries/Press%2BReleases/STIStory_194709.html |access-date=22 September 2019 |website=The Straits Times |date=10 January 2008 |archive-url=https://web.archive.org/web/20101113024022/http://www.straitstimes.com/FTSE%2BST%2BIndex%2BSeries/Press%2BReleases/STIStory_194709.html |archive-date=13 November 2010}}</ref><ref name="C">{{cite news | title = Straits Times Index (STI) | publisher = [[The Straits Times]] | url = http://www.straitstimes.com/FTSE+ST+Index+Series/The+Straits+Times+Index/The+Straits+Times+Index.html | access-date = 28 February 2011 | archive-url = https://web.archive.org/web/20101112022323/http://www.straitstimes.com/FTSE+ST+Index+Series/The+Straits+Times+Index/The+Straits+Times+Index.html | archive-date = 12 November 2010 | url-status = dead }}</ref> Besides the STI, the partners also developed a family of indices including the FTSE ST Dividend Index, FTSE ST China Top tradable index, FTSE ST Catalist Index and FTSE ST Maritime Index as well as 19 Supersector and 39 Sector indices. For the purposes of computing the indices, stocks are classified using the [[Industry Classification Benchmark]] (ICB).

The creation of the FTSE ST Index Series was intended to facilitate the creation of financial products such as institutional and retail funds, [[exchange-traded fund]]s (ETFs), [[derivative (finance)|derivatives]] contracts and other index-linked products.<ref name="D">{{cite news | title = FTSE ST Index Series | publisher = FTSE | url = http://www.ftse.com/Indices/FTSE_ST_Index_Series/index.jsp | url-status = dead | archive-url = https://web.archive.org/web/20091026042334/http://www.ftse.com/Indices/FTSE_ST_Index_Series/index.jsp | archive-date = 26 October 2009 | df = dmy-all }}</ref> There are currently two ETFs listed on the SGX that track the STI: the SPDR Straits Times Index ETF (formerly known as the streetTRACKS Straits Times Index Fund) (managed by [[State Street Global Advisors]]) and the Nikko AM's Singapore STI ETF.
