Why is BSE falling/rising?

As of 25-Aug, BSE Ltd's stock price is currently at 2,290.80, reflecting a decrease of 42.0 points or 1.8%. The stock has underperformed its sector today by 1.64%, and its delivery volume has fallen by 9.7% compared to the 5-day average, indicating a decline in investor participation. While the stock has shown strong long-term performance with a 29.03% increase year-to-date and a remarkable 150.63% rise over the past year, it is currently trading at a premium valuation with a Price to Book Value of 21.1. Despite strong fundamentals, including a 116.05% growth in net profit and consistent positive results over the last ten quarters, the stock's recent price movement reflects concerns over its high valuation relative to peers.
In the broader market context, BSE Ltd's short-term performance has been notably weaker than the benchmark, with a 1-week decline of 8.18% compared to a slight increase of 0.36% in the Sensex. This underperformance highlights the stock's recent struggles despite its impressive long-term returns, which have outpaced the broader market significantly over the past three years. The combination of falling investor participation and high valuation concerns may be contributing to the stock's current downward trend, even as institutional holdings remain strong at 37.03%.
