SEMDEX
The SEMDEX was launched at the inception of the SEM on 5th July 1989 with an index value of 100. SEMDEX was deemed to be an all share index designed to capture the price evolution of all the ordinary shares listed on the Official Market which met the SEM’s free-float requirements as defined in the listing rules of the Official Market. Since 12th September 2016, the SEMDEX (starting at its closing value on 9th September 2016) was converted into an index which tracks the price evolution of all rupee-denominated companies listed on the Official Market which meet the SEM’s free-float requirements.

Calculation

The current value of SEMDEX is expressed in relation to a base value. The Index formula is as follows:

SEMDEX =         Current Market Value of  eligible rupee-denominated Ordinary Shares          x 100

Base Market Value of eligible rupee-denominated Ordinary Shares (Divisor)

Where, the market value of shares of a listed company is equal total number of ordinary shares issued times its closing market price.
