The stock has broken out and was strong in the 9May market when the Nifty lost even 100 points.
It shall remain positive unless the markets tumble.
One may like to buy it out and get out when the stock crosses 500 levels.
The major disadvantage is that the stock is only some points below its recent peak price.the profits will be limited but that is the best policy.
The stock has no weaknesses as per that i understand.
