SEM launches the SEM All Share Index (SEM-ASI) and the SEM-Volume Weighted Average Price Index (SEM-VWAP)

The Stock Exchange of Mauritius launched two new indices, the SEM All Share Index (SEM-ASI) and the SEM Volume Weighted Average Price Index (SEM-VWAP) on September 12, 2016.   

The SEM-ASI includes the current constituents of SEMDEX but also comprises of foreign-currency denominated (USD, EURO, GBP and ZAR), GBC 1 and international companies.  The inclusion of these new constituents will not only boost SEM’s market capitalisation (by Rs 105 billion as of 31st August 2016), but will also give a better reflection of the effective size of our market and enhance the profile of Mauritius as an International Financial Centre.

The SEM also launched the SEM Volume Weighted Average Price Index (SEM-VWAP) on the Official Market which is calculated based on the Volume Weighted Average Price Index (SEM-VWAP) of ordinary shares forming part of SEM-ASI.

The calculations of SEM market indices are based on the last traded price of securities. The SEM VWAP Index provides a new dimension through the use of volume weighted average price as a basis for the calculation of the index.
