As can be seen from the chart given below it is clear that 1900 level looks as a good support for infosys. Considering multiple attempt made by the stock to break it have failed I thing its a support being defended by many.
Now considering the current market price of 1950 one is very close to Stop Loss which reduces your risk (ie Loss in case the stoploss is activated) . This makes taking long postition in Infosys a very low risk proposition.
