Why is BSE falling/rising?

As of 18-Sep, BSE Ltd's stock price is currently at 2,198.30, reflecting a decrease of 11.5 points or 0.52%. Today's performance indicates that the stock has underperformed its sector by 0.85%. The stock's recent returns show a 1.64% increase over the past week, but a significant decline of 11.88% over the last month. Despite strong long-term fundamentals, including a remarkable 97.51% CAGR growth in operating profits and consistent positive results over the last ten quarters, the stock is facing downward pressure. The current valuation appears expensive with a Price to Book Value of 20.2, and a notable drop in investor participation is evident, with delivery volume falling by 54.3% against the five-day average.
In the broader market context, BSE Ltd's short-term performance is slightly below the benchmark Sensex, which has risen by 1.67% over the past week. While the stock has shown impressive long-term returns, including a 69.24% increase over the past year, the recent decline in price may be attributed to its high valuation relative to peers and reduced trading activity, which could signal waning investor interest. The liquidity remains adequate for trading, but the combination of falling delivery volumes and high institutional holdings suggests that while the stock has strong fundamentals, current market dynamics are leading to a decrease in price.
