Why is Castrol India falling/rising?

As of 04-Aug, Castrol India Ltd. is experiencing a price increase, with its current price at 219.60, reflecting a change of 1.19 or 0.54% upward. The stock has been gaining for the last two days, rising 0.76% during this period. It is currently performing inline with its sector, although it has shown mixed performance over different time frames, with a year-to-date return of +11.30% compared to the Sensex's +3.69%. Despite a decline of 15.51% over the past year, the company maintains a high management efficiency with a return on equity (ROE) of 42.39% and a low debt-to-equity ratio, which supports investor confidence. Additionally, the stock has a high dividend yield of 5.98%, which may attract income-focused investors.
In the broader market context, Castrol India's short-term return of +0.41% over the past week outperforms the Sensex's +0.16%, indicating relative strength against the benchmark. However, the stock's performance over the last month shows a decline of 0.57%, contrasting with the Sensex's larger drop of 2.89%. The falling investor participation, as indicated by a decrease in delivery volume, may raise concerns about liquidity, though the stock remains liquid enough for trading. High institutional holdings at 25.24% suggest that knowledgeable investors are backing the stock, which could provide stability amid fluctuating market conditions.
