Why is BSE falling/rising?

As of 05-Aug, BSE Ltd's stock price is currently at Rs 2,363.00, reflecting a decline of Rs 123.6 or 4.97%. The stock has underperformed its sector by 2.2% today and has shown erratic trading patterns, not trading on one day out of the last 20. It touched an intraday low of Rs 2,360, which is a 5.09% decrease. Over the past week, the stock has decreased by 4.99%, and over the past month, it has fallen by 10.33%. Despite these short-term declines, the stock has demonstrated strong long-term performance, with a year-to-date increase of 33.10% and a remarkable 196.87% rise over the past year. The company has shown consistent growth in operating profits and net sales, with high institutional holdings indicating confidence from knowledgeable investors.
In the broader market context, BSE Ltd's recent performance contrasts with the Sensex, which has only decreased by 0.69% over the past week and 3.19% over the past month. This suggests that the stock's decline is more pronounced than the overall market trend. The stock's valuation is considered expensive, with a price-to-book value of 22.2, which may contribute to investor caution. However, the company has a strong track record of positive results over the last nine quarters and a high growth rate in net profits, which could support its long-term prospects despite the current price drop.
