Why is Aditya AMC falling/rising?

As of 19-Sep, Aditya Birla Sun Life AMC Ltd is currently priced at 824.60, reflecting a slight increase of 1.65 (0.2%). The stock has shown a positive performance today, outperforming its sector by 0.35%, and has experienced consecutive gains over the last two days, rising by 0.46% during this period. However, the stock's performance over the past week and month has been negative, with declines of 2.73% and 8.01%, respectively. Despite these short-term challenges, the company has demonstrated strong long-term fundamental strength, evidenced by an average Return on Equity (ROE) of 25.98% and positive financial results, including the highest operating cash flow and net sales growth in recent periods.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has gained 0.88% over the past week and 1.20% over the past month. This indicates that while Aditya Birla Sun Life AMC Ltd has faced short-term headwinds, it has historically outperformed the market over longer periods, generating a 12.38% return in the last year and a significant 74.11% return over the last three years. However, it is important to note that investor participation has decreased, with delivery volume falling by 30.28% against the five-day average, which could impact future price movements.
