Irani told CNBC-TV18, "NIIT Technologies is one of my favourite stocks in the IT space. The stock has gone up mainly because of its inclusion in the F&O segment. Most of the stocks, which normally are going to be in the F&O pack, go up sharply ahead of the actual date. The stock is doing well and it should continue to do well. At the present level, valuation wise I feel it is quite attractive. I have always been positive on it. The stock has gone up a little bit too sharply over the last few days. Possibly, a correction may happen here and there. It's a good buy."
