Why is Aditya AMC falling/rising?

As of 25-Jul, Aditya Birla Sun Life AMC Ltd's stock price is currently at 851.15, reflecting a decline of 25.15 points or 2.87%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decrease of 5.18% during this period. Today's performance shows that the stock has underperformed its sector by 0.75%, with an intraday low of Rs 849.3. In terms of returns, the stock has experienced a 1.77% decline over the past week, while it has shown a positive return of 9.13% over the last month. Despite strong long-term fundamentals, including a high return on equity of 25.98% and impressive quarterly results, the stock is facing pressure due to its high valuation and a PEG ratio of 1.5, indicating it may be overvalued compared to its earnings growth.
Broader Market Context: In the context of the broader market, the stock's recent performance contrasts with the Sensex, which has only declined by 0.36% over the past week. The finance/NBFC sector, to which Aditya AMC belongs, has also seen a downturn of 2.13%. While the stock has outperformed the benchmark over longer periods, its short-term struggles, combined with falling investor participation and a decrease in delivery volume, suggest a cautious sentiment among investors. The stock's high dividend yield of 4.28% may provide some support, but the recent price movements indicate that investors are currently reacting to the perceived overvaluation and recent performance trends.
