New Delhi, Aug. 21 -- Breakout stocks to buy or sell: Extending their winning streak for the fifth straight session, Indian stock market benchmarks - the Sensex and Nifty 50 - closed with modest gains on Wednesday, August 20. Positive sentiment was driven by proposed GST reforms, an S&P Global upgrade of India's credit rating, and indications that the Russia-Ukraine conflict may be nearing resolution. However, gains were limited by concerns over the upcoming August 27 deadline for Trump's secondary tariffs.

The Sensex climbed 213 points, or 0.26%, to close at 81,857.84, while the Nifty 50 gained 70 points, or 0.28%, to finish at 25,050.55. Meanwhile, the BSE Midcap and Smallcap indices advanced 0.39% and 0.30%, respectively.
