Why is C P C L falling/rising?

As of 11-Jul, Chennai Petroleum Corporation Ltd's stock price is currently at 720.10, reflecting a decrease of 13.15 points or 1.79%. The stock has been underperforming, having fallen consecutively for the last two days, resulting in a total decline of 2.49% in that period. Today's performance indicates that it has underperformed its sector by 0.45%. Additionally, the stock's delivery volume has significantly decreased by 70.76% compared to the five-day average, suggesting a decline in investor participation. Despite these challenges, the company boasts a high dividend yield of 7.5% and strong management efficiency, with a return on capital employed (ROCE) of 23.43%. However, over the past year, the stock has seen a substantial drop of 31.46%, coinciding with a dramatic profit decline of 92.2%.
In the broader market context, the stock's short-term performance has been notably weaker than the benchmark Sensex, which has only declined by 1.12% over the past week. While the stock has shown positive returns over the longer term, such as a 5.39% increase over the past month and a remarkable 171.58% rise over three years, the recent downward trend raises concerns. The stock's current valuation appears attractive compared to its peers, but the significant drop in profits and recent underperformance relative to both the sector and the benchmark may be contributing to the current price decline.
