The Sensex is likely to open on a positive note, and surge to newer heights in early trades. However, the latter half of the day could see the index exhibit volatile movements owing to expiry related pressure.The Sensex may face resistance around the 11,120-11,140 range, while on the downside the index is likely to find support around 11,039 levels.The high put-call ratio (PCR) of Nifty, which is at 2, is also a major cause for concern.
