Monday, 12 September 2016, sees the launch of the SEM All Share Index ("SEM-ASI") and the SEM Volume Weighted Average Price Index ("SEM-VWAP") by the Stock Exchange of Mauritius ("SEM") in a bid to internationalise its platform.


The SEM-ASI has been designed to comprise all the companies listed on the Official Market that meet the SEM's free-float requirements, including rupee-based companies, as well as foreign-currency denominated companies.

The SEM-ASI will now include and track the performance of Global Business Category 1 Companies ("GBC1") not previously included in current index, the SEMDEX, to give a more accurate reflection of the size of the Mauritian market and add to the substance of its international financial centre. 

Operators of the global business industry welcome this initiative, which will, as stated by the SEM, "consolidate the synergistic link between the global business sector and the SEM".


The SEM-VWAP will be calculated based on the volume weighted average price of ordinary shares forming part of the SEM-ASI. The SEM-VWAP is intended to partially lessen the fluctuations created by small volume transactions on market indices.
