Why is Nippon Life Ind. falling/rising?

As of 26-Aug, Nippon Life India Asset Management Ltd is experiencing a decline in its stock price, currently at 825.55, which reflects a decrease of 16.35 or 1.94%. The stock has been losing momentum for the last two days, with a total drop of 4.48% during this period. It touched an intraday low of Rs 815, indicating a significant downward movement. Despite its strong long-term fundamentals, including a robust average Return on Equity (ROE) of 24.45% and healthy growth in operating profit, the stock's recent performance has been affected by a decline in investor participation, as evidenced by a 12.7% drop in delivery volume compared to the five-day average. Furthermore, while the stock has outperformed the benchmark in the long term, its recent returns over the past week show a decline of 3.98%, contrasting with the Sensex's smaller drop of 1.05%.
In the broader market context, the finance/NBFC sector has also faced challenges, with a decline of 2.02%, which may be contributing to the downward pressure on Nippon Life's stock. Although the stock has shown impressive long-term performance, with a 167.82% increase over three years, the current valuation appears high, with a Price to Book Value of 12.5, leading to concerns about its sustainability. The stock's recent performance, combined with falling investor participation and sector-wide declines, suggests that while the company has strong fundamentals, external market conditions and valuation concerns are influencing its current price movement negatively.
