Vinod,
The markets are nervous due to external events, specifically the possibility of Greek default. (Greece has to pay 6 Bil. Euros to EU/IMF - a few tranches which it has deferred to end of this month) So one has to follow this event, and if Greece defaults there will be global contagion - But this is a known event and may be factored in the price. Presently, Nobody can foresee what the outcome of this event will be, though it would seem that good sense will prevail and everybody will make some compromises to their positions. So in view of this uncertainity, and till the time this event is resolved, there will be pressure on the markets..... and it is unlikely (though not impossible) that Nifty will cross 9K this month end.....
Just my view....
