The Calculation Of RTS Current Quotes Index (RTST) Will Be Stopped On August 19,2005

The calculation of RTS current quotes index (RTST) will be stopped on August 19,2005. RTS Board of Directors came up with this decision because the RTS index is calculated online during trading session after change in the price of every stock quote.

Before April 13, 2004, RTST was called "Technical Index". Technical Index was created in order to help tracking the market situation and was being calculated since 1998 using the same method as the one used for RTS Index calculation. However, best quotes prices were used instead.
