Stock markets on Friday managed modest gains with a 59-point upward move in the benchmark Sensex, helped by good buying in heavyweights like Reliance Industries and Bharti Airtel, as also positive global cues.

The Sensex, which had gained nearly 380 points in the last three sessions, added 44.54 points at 17,563.80 points in the first five minutes of trading.

The rupee on Thursday weakened by 10 paise against the US currency to close at 45.44/45 on increased dollar buying by importers, mainly oil refiners.

The stock market today nudged 29 points higher after a volatile session with Infosys and RIL leading the charge, after global rating agency S&P revised its outlook on India's finances to stable from negative.

The Indian rupee appreciated by 15 paise to 45.43 a dollar in the early trade on Wednesday amid increased capital inflows by foreign funds into equities.
