Yesterday's downmove & today's upmove caught everyone by surprise. Now shorts are trapped, above 8250 more short covering will come which might push Nifty into heavy resistance zone 8350-8450. Don't forget Market is in bear grip until 8600 is crossed on a weekly closing basis. Bears will be comfortable selling in the 8350-8450 zone for a target of 7900-8000. Let's see how it unfolds.
