Why is Castrol India falling/rising?

As of 31-Jul, Castrol India Ltd. is experiencing a decline in its stock price, currently at 217.95, reflecting a decrease of 2.25 or 1.02%. The stock has been losing value for the last two days, with a total drop of 2% during this period. Despite its current price being above the 50-day, 100-day, and 200-day moving averages, it is below the 5-day and 20-day moving averages. Additionally, the stock has shown a negative return of 4.39% over the past week and 2.98% over the past month, while it has a year-to-date return of 10.47%. The falling investor participation is notable, with a delivery volume that has decreased by 59.61% compared to the 5-day average. However, the stock benefits from a high dividend yield of 5.9% and strong management efficiency, indicated by a high return on equity of 42.39%.
In the broader market context, Castrol India's recent performance contrasts with the Sensex, which has declined by 1.22% over the past week and 3.00% over the past month. While the stock has shown resilience with a year-to-date return significantly higher than the benchmark, its one-year performance is concerning, with a drop of 16.88% compared to the Sensex's minor decline. The company maintains a low debt-to-equity ratio and high institutional holdings at 25.24%, suggesting a solid foundation and confidence from larger investors. However, the recent price movement indicates that despite these strengths, the stock is currently under pressure, likely influenced by reduced trading activity and recent performance trends.
