As Foolish investors may know, the Straits Times Index (SGX: ^STI), the most prominent market benchmark in Singapore, is made up of 30 different stocks.
What may not be that well-known is that the list of 30 is reviewed on a quarterly basis to determine whether any changes should be made.
In a joint press release yesterday, the index’s three co-creators – Singapore Press Holdings Limited (SGX: T39), Singapore Exchange Limited (SGX: S68), and FTSE Russell – announced that Sembcorp Marine Ltd (SGX: S51) will be dropped from the index.
Sembcorp Marine has seen its shares fall by nearly 70% in price over the past two years. Its business too, has suffered. The company’s a builder of oil rigs and the sharp fall in oil prices seen in recent years have had negative impacts. As an illustration, Sembcorp Marine’s profit of S$560.1 million in 2014 had become a loss of S$289.7 million in 2015.
Sembcorp Marine’s parent, Sembcorp Industries Limited (SGX: U96), still remains a part of the Straits Times Index.
You say goodbye, I say hello
Jardine Matheson plays host to a number of Singapore-listed companies. The conglomerate has stakes in another two Straits Times Index components, namely, Jardine Cycle & Carriage Ltd (SGX: C07) and Hongkong Land Holdings Limited (SGX: H78).
For context, Jardine Matheson was officially booted out of the Straits Times Index on 21 September 2015 when its share price was US$47. At yesterday’s market close, Jardine Matheson’s shares were trading at US$60.
The new benchwarmers
As part of the update on the index, the reserve list – a list of shares that are next in line to replace any of the Straits Times Index’s current constituents – also saw some changes.
The new reserve list consists of Singapore Post Limited (SGX: S08), Keppel REIT (SGX: K17), Suntec Real Estate Investment Trust (SGX: T82U), Mapletree Industrial Trust (SGX: ME8U), and Mapletree Commercial Trust (SGX: N2IU).
Interestingly, there are four real estate investment trusts (REIT) in the reserve list.
Companies that get chosen to enter a stock market index can sometimes see short-term bumps to their share prices as index funds have to buy their shares to reflect the changes. Over the long-term though, our focus as investors should be on the quality of the underlying business.
