Why is Castrol India falling/rising?

As of 29-Jul, Castrol India Ltd. is experiencing a price increase, currently at 222.40, reflecting a rise of 3.7 or 1.69%. The stock has shown a trend reversal, gaining after three consecutive days of decline. Despite a decrease in delivery volume by 44.75% against the 5-day average, the stock remains above its 50-day, 100-day, and 200-day moving averages, indicating a relatively strong position. Over the past week, Castrol India has outperformed the Sensex, with a return of +1.14% compared to the benchmark's -1.03%. Additionally, the company boasts a high return on equity (ROE) of 42.39%, a low debt-to-equity ratio, and significant institutional holdings at 25.24%, which contribute positively to investor confidence.
In the broader market context, while Castrol India has shown resilience with a year-to-date return of +12.72%, the Sensex has only increased by 4.09% during the same period. This suggests that Castrol India is performing well relative to the overall market. However, the stock's one-year performance shows a decline of 17.05%, contrasting with the Sensex's minimal change of -0.02%, indicating that the stock has faced challenges over a longer horizon. The company's substantial market capitalization of Rs 21,632 crore and its dominance in the sector, accounting for 57.50% of the industry, further support its current upward price movement despite recent volatility.
