What you need to know about the RTS index.
The index can trace its roots all the way back to September 1995, when it started with a base value of just 100.
The 50 companies which form the RTSI are revised by the RTS Information Committee on a quarterly basis, to ensure it's kept up to date and accurate.
The RTSI, which is a capitalisation weighted composite index, is rare in that it's one of the few indices outside of the US itself to be calculated in dollars.
