Why is Castrol India falling/rising?

As of 30-Jul, Castrol India Ltd. is currently priced at 220.20, reflecting a decrease of 2.2 points or 0.99%. The stock has underperformed its sector by 0.86% today, and its delivery volume has significantly dropped by 60.48% compared to the 5-day average, indicating falling investor participation. Over the past week, the stock has declined by 3.72%, while it has shown a year-to-date increase of 11.61%. Despite its high management efficiency, with a return on equity (ROE) of 42.39%, and a low debt-to-equity ratio, the stock's recent performance has been negatively impacted by its underwhelming short-term returns and reduced trading activity.
In the broader market context, Castrol India's performance over the past week has been worse than the benchmark Sensex, which has only declined by 1.50%. The stock's year-on-year performance shows a significant drop of 18.82%, contrasting with the Sensex's minimal change of 0.03%. While the company maintains a strong position in the sector with high institutional holdings and a substantial market cap, these factors have not been sufficient to counteract the recent downward pressure on the stock price. Overall, the combination of declining investor interest and underperformance relative to the benchmark has contributed to the stock's current downward trend.
