Gaba told CNBC-TV18, "Elder Pharma is trading at all time high, Rs 420, I would say that these are the regions where it looks tired but it is trading at all time high, there is no sign of weakness but tiredness is there. I would look for a first sign of confirmation and the first sign of confirmation will come when it starts trade above Rs 420. If that happens then maybe all time high will be taken up and go further up. Rs 360 has been a very strong support."
