How to trade a news-driven move

A stock in the news needs volume confirmation: a gap without above-average volume tends to fill within the session, while a gap with heavy volume that holds its opening range usually continues. Before acting, check whether the trigger changes earnings power — an order win, a margin guidance change or a results beat — or whether it is a one-off event already in the price. Position size around the day's range, not around the headline.

Key takeaways

  • Top gainer: HDFC LIFE INS CO LTD (+4.85%) — higher at the time of writing
  • Top loser: OIL AND NATURAL GAS CORP. (-1.99%) — lower at the time of writing

About this report

Every figure on this page is read from a primary source at the timestamp shown — exchange boards for equities and indices, the exchange bid book for IPOs, published association rates for bullion, and consolidated exchange quotes for crypto — with no estimation or third-party commentary. Historical fields such as trailing returns and 52-week extremes are computed on the adjusted daily series so splits and bonuses do not create false gaps. A timestamp outside market hours reflects the last traded or last published value, not a live tick.

This report is generated automatically from live exchange and official association data at the time stamped above. Prices move continuously — verify on the source before acting. Nothing here is investment advice.
