Paytm and Sudeep Pharma surged as 7 stocks swung hard despite weak Sensex close

Some moves were fueled by upgrades and tariffs, not broad market strength

But action was stock-specific, as Paytm, Sudeep Pharma, M&M, Reliance Infrastructure, GAIL and GMDC saw sharp swings. The catalysts ranged from upgrades and new listings to tariff moves and profit-booking, underscoring how headlines—not the broader market—drove trading.
