Why is Castrol India falling/rising?

As of 18-Jul, Castrol India Ltd. is experiencing a decline in its stock price, currently at Rs 221.50, reflecting a decrease of Rs 2.1 or 0.94%. The stock has shown a performance today that is in line with its sector, having touched an intraday low of Rs 219.1. Despite being higher than the 20-day, 50-day, 100-day, and 200-day moving averages, it is lower than the 5-day moving average. Additionally, there has been a significant drop in investor participation, with delivery volume falling by 64.39% compared to the 5-day average. Over the past week, the stock has gained 0.68%, while it has increased by 6.46% over the past month, although it has seen a year-to-date rise of 12.27%. The company boasts a high management efficiency with a return on equity of 42.39% and a low debt-to-equity ratio, which may provide some support to its valuation despite the recent price decline.
In the broader market context, the Sensex has decreased by 0.90% over the past week, indicating that the stock's short-term performance is relatively better than the benchmark. However, over the past year, Castrol India has underperformed, with a decline of 15.07% compared to a modest gain of 0.51% for the Sensex. The stock's high institutional holdings at 25.24% suggest that more informed investors are backing the company, which could provide some stability. Despite its strong market position, constituting 56.83% of its sector, the recent drop in delivery volumes and the stock's performance relative to moving averages may indicate a cautious sentiment among investors.
