Why is BSE falling/rising?

As of 28-Aug, BSE Ltd's stock price is currently at 2,178.40, reflecting a decrease of 37.2 points or 1.68%. The stock has underperformed its sector by 0.58% today, and its moving averages indicate a mixed performance, being higher than the 200-day moving average but lower than the 5, 20, 50, and 100-day averages. Despite this recent decline, the stock has shown strong long-term performance, with a year-to-date increase of 22.70% and an impressive 134.99% rise over the past year. The company has consistently reported positive results for the last ten quarters, with a significant growth in net profit and operating profits, contributing to its strong fundamentals. However, the stock is considered expensive with a high price-to-book value, which may deter some investors.
In the broader market context, BSE Ltd's short-term performance has been notably weaker than the benchmark Sensex, which has declined by only 2.32% over the past week compared to BSE's 6.59% drop. This underperformance in the short term could be attributed to the stock's high valuation relative to its peers, despite its strong growth metrics. The rising investor participation, indicated by an increase in delivery volume, suggests some level of confidence among investors, but the overall market sentiment appears to be cautious given the stock's recent price movement and the broader market's performance.
