Sensex edges higher; blue-chips gain

MUMBAI (Reuters) - The BSE Sensex provisionally edged higher on Friday as continued strong foreign buying boosted blue-chips such as Larsen & Toubro , although some caution also set in about the pace of recent gains.

Both the BSE and NSE indexes posted mild losses for the week, snapping a three-week winning streak as investors also booked profits in some recent gainers.

The benchmark BSE Sensex provisionally rose 0.1 percent to 21,797.16 points, while the broader Nifty provisionally rose 0.17 percent to 6,504.20 points.
