Even though the stock market, BSE (Bombay Stock Exchange), has been in operation for than a century, the markets are not yet as efficient, liquid and transparent as those in the western world. Many rules are being tightened, and more information being provided to shareholders, but playing the market individually continues to be tough game. Institutional investors rule the roost, and are the safest means to take advantage of the stock market boom in India.
There are two main choices to be made regarding purchasing an India mutual fund - do you pick a fund operated in India, or a fund that runs in the US (or in the developed part of the world) that invests in India. There are many good choices in either situation. For the moment, focusing on mutual funds that operate from the US, we could recommend either the closed end fund The India Fund (IFN), Morgan Stanley India Investment Fund (IIF) or perhaps the MSCI India ETF that trades on Singapore exchange. For a more diversified emerging markets exposure, T Rowe Price Emerging Markets fund has shown the maturity to deal with vagaries of the markets in India, China and other developing countries.
Alternatively, you could build your own India portfolio that acts as a mutual fund by buying stocks of a diversified group of companies that trade on the US stock exchange. A good set of companies to watch for are VSNL (Videsh Sanchar Nigam Limited) which provides internet services; MTNL (Mahanagar Telephone Nigam Limited), which provides phone connections, including wireless; Infosys, which is a software services and solutions provider; Wipro, another software services providers; Reliance Petrochemicals - for a play in the growing energy sector; ICICI - which is a bank that is expanding profitably into rural India (where the majority of the population lives and is underserved). Adding a few more large-cap stocks to complete your diversification mix, you will have your own India mutual fund for your portfolio.
If you have a 10-year investment window available for your money, definitely expose yourself to the Indian stock market, there is a large opportunity still awaiting the prudent investor.
