Stay away from the Stock Market. The current boom is artificial, funded by US Financial Institutions borrowing money at near to 0% interest in US and investing in India, a high interest regime. A situation similar to what happened when the stock market crashed in 2008 due to outflow of FII money is strongly indicated.
If you have bought stocks earlier when the Sensex was around 17000, book your profit, and stay out of the stock market. Wait for the inevitatable crash to buy again low.
And disregard the statement of the honourable PM that the foreign money inflow is not a cause for worry. He is bluffing, and using the artificial rise in stock indices to prop up a beleagured Prime Ministership.
