Trading volume exploded to over 1.15 million shares, with a value turnover of ₹218.48 crores, placing it among the most actively traded stocks by value.

Institutional interest was evident with delivery volumes rising 125.86% compared to the five-day average, signalling strong accumulation. The surge in call option activity, particularly at the ₹400 strike price for September expiry, reflected bullish sentiment among derivatives traders. Open interest jumped 40.56%, reinforcing expectations of continued upward momentum.

4 September: Fresh 52-Week High and Continued Open Interest Surge

RBL Bank extended its winning streak to four consecutive sessions, hitting a new 52-week high of Rs.412.9 and closing at Rs.414.35, up 1.56% on the day.
