Why is C P C L falling/rising?

As of 09-Jul, Chennai Petroleum Corporation Ltd (CPCL) is experiencing a price increase, currently at Rs 738.50, which reflects a rise of 4.3 points or 0.59%. The stock has shown a positive performance today, outperforming its sector by 1.73% and reversing a trend after two consecutive days of decline. It reached an intraday high of Rs 755.55, indicating strong intraday momentum. Over the past week, CPCL has gained 5.45%, and over the past month, it has increased by 12.55%. Despite a significant decline of 27.80% over the past year, the stock's high dividend yield of 7.49% and strong management efficiency, evidenced by a high return on capital employed (ROCE) of 23.43%, suggest a favorable long-term outlook.
In the broader market context, CPCL's recent performance contrasts sharply with the Sensex, which has only increased by 0.15% over the past week. This indicates that CPCL is outperforming the market significantly in the short term. However, the stock's declining delivery volume, which has fallen by 63.15% against the 5-day average, suggests a decrease in investor participation. Despite this, the stock's attractive valuation compared to peers and its healthy long-term growth potential, with an annual operating profit growth rate of 16.57%, contribute positively to its recent price movement.
