Gaba told CNBC-TV18, "GSS America Infotech has strong support at Rs 680-690. If I had the stock then I would have moved with the trailing stoploss and have a stoploss below Rs 680, of course trading point of view it could be profits and loss but since I am in it, I would like to have a stop below Rs 680 and ride if it is going up but if it breaks I will be out of it. In case if one is going to shut this stock, if it breaks Rs 600 I will completely exit the stock."
