The market has priced in a NDA majority but the jury is out on whether it has priced-in a 270 or 320 or 340. Now, if that is actually the case, it would be tough to see Nifty beyond 12,000 given the current global cues.
The market is not prepared for any negative outcome and so it could get very vulnerable if the outcome is slightly negative. There could be some volatility in the first couple of hours of trade.
While trading the options, please avoid selling the naked Calls or Puts because we do not know what the market may do, right now the Options data is indicating a 700-point Nifty range going by in-the-money Call and Put Option. However, on result day, the market can move beyond that as well intra-day.
