Why is Aditya AMC falling/rising?

As of 22-Sep, Aditya Birla Sun Life AMC Ltd is experiencing a decline in its stock price, currently at 814.70, which reflects a decrease of 9.4 points or 1.14%. The stock has underperformed its sector by 1.56% today and has seen a trend reversal after two consecutive days of gains. Over the past week, the stock has dropped by 3.22%, and over the last month, it has decreased by 7.89%. Despite this short-term decline, the company has demonstrated strong long-term fundamentals, with an average Return on Equity (ROE) of 25.98% and positive operating cash flow results, indicating solid financial health.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has gained 0.46% over the past week and 1.05% over the past month. This underperformance is notable, especially as the stock has generated a 7.90% return over the past year, outperforming the BSE500 in the long term. The rising investor participation, evidenced by a significant increase in delivery volume, suggests that while the stock is currently facing downward pressure, there is still interest from investors, which may support future price recovery.
