We don't want to worry about US economym whether it is going up or down. The whole US is paying for its sins. It is under severe curse of people all over the world for its tyranny. It is surely destined to doom in the years to come, it is not far away. You are under wrong impression that all the FII are American. Try to correct yourself. Whether these FIIs mostly non-americans, buy indian stocks or not, indian stock markets are poised to grow leap and bound as indian financial institutions, mutual funds are eagerly patricipating in the market-economy and that is the trigger for market-boom. Even otherwise, most of the indians, who are retail investors, learn the tricks of the share markets and actively participate in it. Further, the indian corporate houses have grown so much that they started buying foreign companies bigger than themselves and in a stiff cut-throat competition. In India, our only enemy is COMMUNALISM that is perpetuated in the name of NATIONALISM AND PATRIOTISM that should be eradicated and the backbones of communical and criminal elements should be broken to make them bed-ridden and/or dead for ever. Otherwise, there is no worry of stock-market falling rapidly even after all FII totally leaving India for green pastures.
