As i have mentioned before Expo is a gem but timing of purchase is also important. Best time to purchase had aleady passed at 40+ and early 50's.
I would say if there is any one eyeing to buy now, be patient till it goes through a correction. It might even touch Rs.90 and then consolidate there in the price range of Rs.85 to Rs.90 but better to buy then knowing the price has settled.
Humble opinion. The potentiol to touch 100 as many know already is on the cards with a question of when.
In the end it is about risks and rewards. Think wisely because many including me would not eye to buy now but would have purchased before last week, now waiting for the share to realize its potential.
