Why is AU Small Finance falling/rising?

As of 29-Aug, AU Small Finance Bank Ltd's stock price is currently at 718.10, reflecting a decrease of 11.55 points or 1.58%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decline of 4.13% during this period. Additionally, the stock's performance over the past week and month shows declines of 3.27% and 2.98%, respectively, while year-to-date, it has still managed a positive return of 28.67%. The stock is currently trading above its 200-day moving average but below its shorter-term moving averages, indicating mixed momentum. Furthermore, there has been a notable decrease in investor participation, with delivery volume dropping by 32.11% compared to the five-day average, which may contribute to the downward pressure on the stock price.
In the broader market context, the stock has outperformed the benchmark Sensex over the past year, generating a return of 12.14% compared to the Sensex's decline of 2.83%. However, in the short term, the stock's performance has lagged behind the benchmark, which has seen a decline of 1.84% over the past week. Despite the recent price drop, the company has demonstrated strong long-term fundamentals, including a high Capital Adequacy Ratio and consistent positive quarterly results. However, concerns regarding its valuation, indicated by a Price to Book Value of 3.1 and a relatively lower Return on Assets, may be contributing to the stock's recent struggles.
