Why is Bandhan Bank falling/rising?

As of 22-Sep, Bandhan Bank Ltd. is experiencing a decline in its stock price, currently at Rs 163.05, which reflects a decrease of Rs 4.1 or 2.45%. The stock has underperformed its sector by 2.25% today and has fallen after four consecutive days of gains. It reached an intraday low of Rs 162.7, indicating a drop of 2.66%. Over the past week, the stock has shown a slight increase of 0.56%, but it has significantly underperformed over the last month with a decline of 5.89%. The stock's performance over the past year has been particularly poor, with a return of -22.30%, while its profits have decreased by 20.2%. Despite a high net interest margin and rising promoter confidence, the company has reported negative results for the last three quarters, which has contributed to the stock's downward trend.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has underperformed the Sensex, which has gained 0.46% over the past week. The stock's long-term performance is also concerning, with a significant decline of 43.25% over the last three years compared to the Sensex's increase of 38.97%. This consistent underperformance against the benchmark, coupled with high gross non-performing assets at 4.96%, has likely influenced investor sentiment negatively, leading to the current decline in stock price.
