Prakash Gaba of prakashgaba.com told CNBC-TV18, "HDFC Bank is a darling, it is always a buy, it is always a hold and never a sell. I bought this stock at IPO, I am holding it.""I expect it to go higher. I have seen the chart, it is a beautiful chart, any weakness gets bought into. So it is a fine opportunity, never sell the stock buy if you can and if you cannot hold it," he said.
