With increasing inflows of foreign direct investment (FDI) and as Indian equity markets integrate rapidly with global capital markets, the Dollex indices take into account currency fluctuations to show Indian growth in dollar terms. They are international benchmarks for the Indian market and reflect changes in both stock prices and exchange rates. As a result, they are useful to foreign investors looking to measure the "real returns" of their investments in the Indian market.
The Dollex indices are calculated at the end of each trading session by taking considering the day's rupee-dollar reference rate as announced by the Reserve Bank of India (RBI), India's central bank.
Dollex = Index Value (in INR) * Base INR-USD Rate
