Pre-market action: Here's the trade setup for today's session

"Although Nifty opens positive, it is witnessing resistance at higher levels, indicating cautiousness among the investors with the progress of both the result season and the Lok Sabha election. We expect this volatile move to continue till the Exit poll. Hence market to remain in a broader range until clarity emerges," said Siddhartha Khemka, Head - Retail Research, Motilal Oswal.
