Domestic benchmark equity indices today ended with losses amid sell-off in specific stocks, persistent foreign fund outflows and weak global cues. The 30-share BSE Sensex dipped 422 points, or 0.54 percent, to close at 77,156, while the NSE Nifty50 fell 169 points, or 0.72 percent, to settle at 23,350. The broader market at the Bombay Stock Exchange also ended in negative territory. The Mid-Cap index slipped 0.37 percent and the Small-Cap index dropped over half percent.
