Why is BSE falling/rising?

As of 26-Aug, BSE Ltd's stock price is currently at 2,215.60, reflecting a decline of 75.2 points, or 3.28%. The stock has underperformed its sector by 1.46% today, and its delivery volume has decreased by 4.39% against the 5-day average, indicating a drop in investor participation. Despite its strong long-term fundamentals, including a remarkable 97.51% CAGR growth in operating profits and consistent positive results over the last 10 quarters, the stock's recent performance has been lackluster, with a 1-week return of -11.07% and a 1-month return of -9.71%. The stock is trading at a premium compared to its peers, which may be contributing to its downward pressure.
In the broader market context, the Sensex has only declined by 1.08% over the past week, suggesting that BSE Ltd's short-term performance is significantly worse than the overall market. While the stock has shown impressive long-term returns, including a 143.65% increase over the past year, the recent drop in price may be attributed to its high valuation metrics, such as a Price to Book Value of 20.3, which could deter some investors. The combination of falling investor participation and a premium valuation relative to historical averages may be causing the stock to face downward pressure, despite its strong fundamentals and institutional backing.
