My personal views, so should be taken with proper discretion by anyone.
Market discounts quickly than we think since all of it happens in anticipation. By the looks of it as you see some discounting is already done. If the last phase does not bring any major surprises, picture gets more clear by 1st June onwards when exit polls get accumulated. 2nd-3rd June likely reciprocates what happens on 1st June. If the anticipations are factored in by 3rd, the final seat count will be the trigger for further movement.
Higher than anticipated, you are likely to see a quick upmove and consolidation and down post that since the over hang is removed. Less than anticipated and you see an unpleasant reaction. On either side it gets extreme, more so on the downside. This whole thing could last for a few days to a week as more news comes in.
As for SMEs listing on 3rd, 4th and onwards, i again say regardless of GMP, if the company is good, it may not perform as per GMP and disappoint in short term but will revive quick and will be rewarding going ahead where patience plays the key.
Awaiting inputs from other members of how they assess.
