the world markets are falling very substantially on european growth stalling, european debt and financial regulation... most of this is as a result of panic selling which is bound to affect the NSE since there is a huge foreign presence....
but if one bought at around january then i wouoldnt advise selling especially since the fundamentals for a world recovery are firmly in place and this is just widespread panic...
though i would advise that investors stock up on cash because we may be in for a roller coaster after yesterday...
