Markets snap three-day rally ahead of F&O expiry; broader markets in green

The benchmark indices on Thursday snapped three-session long gaining streak tracking negative global cues after US president Donald Trump's long-awaited tax plan failed to enthuse investors, while back home derivatives expiry of the April series, due later in the day, kept the momentum cautious.

At 12:31 pm, the S&P BSE Sensex was trading at 30,082, down 50 points, while the Nifty50 was ruling at 9,345, down 6 points. Both the indices had settled at their record closing highs in the previous session. 

In the broader market, the S&P BSE Midcap index and the S&P BSE Smallcap index added 0.2% each.
