Investors should keep a close eye on stocks like BSE (NSE: BSE), LIC (NSE: LICI), Titan (NSE: TITAN), HPCL (NSE: HINDPETRO), NALCO (NSE: NATIONALUM), and Kalyan Jewellers (NSE: KALYANKJIL), as strong Q1 results boost sentiment, while Sun TV (NSE: SUNTV) and Apollo Tyres (NSE: APOLLOTYRE) posted weak earnings.
