Why is Bandhan Bank falling/rising?

As of 04-Sep, Bandhan Bank Ltd. is experiencing a decline in its stock price, currently at 162.45, which reflects a decrease of 2.15 or 1.31%. The stock has underperformed its sector by 1.62% today and has fallen after two consecutive days of gains. Additionally, the stock's performance over the past week shows a slight decline of 0.21%, while it has dropped 3.36% over the past month. Despite a high net interest margin of 12.03% and a solid capital adequacy ratio of 18.66%, the stock has generated a significant return of -18.65% over the past year, coinciding with a 20.2% drop in profits. The recent decrease in delivery volume by 47.32% against the 5-day average indicates falling investor participation, which may contribute to the stock's downward movement.
In the broader market context, Bandhan Bank's recent performance contrasts with the Sensex, which has gained 0.80% over the past week. While the stock has shown a year-to-date increase of 2.17%, it lags behind the benchmark's 3.30% gain. The stock's long-term performance is concerning, with a 41.17% decline over three years compared to the Sensex's 37.27% increase. The rising promoter confidence, with a 0.94% increase in their stake, suggests some optimism about the company's future, but the overall market sentiment and recent performance metrics indicate a challenging environment for Bandhan Bank.
