Why is BSE falling/rising?

As of 24-Sep, BSE Ltd's stock price is currently at 2,076.40, reflecting a decline of 45.8 points or 2.16%. The stock has underperformed its sector today by 2.07%, and it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has decreased by 6.04%, while it has seen a more significant drop of 10.99% over the past month. Despite these short-term declines, the company has demonstrated strong long-term fundamentals, with a remarkable 97.51% CAGR growth in operating profits and consistent positive results over the last ten quarters. However, the stock's high valuation, indicated by a Price to Book Value of 19.1, may be contributing to the recent price drop as it trades at a premium compared to peers.
In the broader market context, the Sensex has only declined by 1.08% over the past week, indicating that BSE Ltd's short-term performance is lagging behind the benchmark. While the stock has generated a substantial return of 56.48% over the past year, its recent performance contrasts sharply with the Sensex's modest gain of 5.97% during the same period. The rising investor participation, with a delivery volume increase of 49.28%, suggests some underlying interest in the stock, but the overall market sentiment and the stock's expensive valuation may be weighing on its price.
