This was a historical moment of sensex getting lower, and as per norms, the BSE and NSE was stopped for an hour.

Exactly two years after that Black Monday, on 18th May 2006, the sensex again crashed nearly 7 percent. It was primarily due to fears of a new tax on FIIs.

Now this ‘May of even numbered year (2012)’ has come and there are host of notions, both domestic and global issues are affecting investors, like the controversial General Anti-Avoidance Rule (GAAR) which aims mainly to tax errant overseas investors misusing the tax treaties.
