Manghnani told CNBC-TV18, "Rs 1,900 is a major support for Infosys; the reason I say this because in the last three-four months it bounced back from Rs 1,908-1910 levels. I still probably go on a hunch and try to play more in the rupee front and till the rupee doesn't break Rs 40 I will hold on to these stocks. But as a day trader, it gets a little tricky to how long one can wait so Rs 1,900 if Infosys breaks that could be some problem for it."
He further added, "I think TCS support will be Rs 1,210-1,200."
