The Bank Nifty bears took over control and the index fell by more than 2 percentbreaking the support of the 43,000-42,800 zone. The index if sustained below 43000 will witness further correction towards the 42,500-42,300 zone where the next demand area is visible. The upside resistance of 43,000 if taken out decisively will lead to further short covering toward 43,300 levels.
