Why is BSE falling/rising?

As of 12-Jun, BSE Ltd's stock price is currently at 2,754.10, reflecting a decline of 128.3 points, or 4.45%. Today's performance indicates that the stock has underperformed its sector by 2.99%. Despite this decline, the stock has shown strong long-term performance, with a year-to-date return of 55.13% and a remarkable 205.65% increase over the past year. The company has demonstrated consistent growth, with a 479.51% increase in net profit and positive results for the last nine consecutive quarters. However, the stock is considered expensive, trading at a premium compared to its peers, which may contribute to the recent price drop.
In the broader market context, the Sensex has increased by 0.55% over the past week, contrasting with BSE Ltd's decline of 5.35% during the same period. This suggests that while the overall market is experiencing a slight uptick, BSE Ltd is facing specific challenges that are impacting its stock price negatively. The stock's higher liquidity and rising investor participation, with a significant increase in delivery volume, indicate ongoing interest; however, the expensive valuation and potential market corrections may be influencing the current downward trend.
