Why is C P C L falling/rising?

As of 31-Jul, Chennai Petroleum Corporation Ltd's stock price is currently at 682.20, reflecting a decrease of 18.3 points or 2.61%. The stock has been underperforming, having fallen consecutively for the last three days, resulting in a total decline of 4.93% during this period. It opened with a loss of 2.43% today and reached an intraday low of Rs 678.05. Over the past week, the stock has decreased by 10.35%, while its performance over the last year shows a significant decline of 31.57%. The company has experienced negative results in its latest quarter, with a profit before tax of Rs -72.83 crore and a profit after tax of Rs -40.10 crore, both of which are substantially lower than previous averages. Additionally, there has been a notable drop in investor participation, with delivery volume decreasing by 57.13% compared to the five-day average.
In the broader market context, the stock's performance has been significantly worse than the benchmark, as it has underperformed the Sensex, which fell by only 1.22% over the past week. While the stock has shown some long-term growth with an annual net sales increase of 13.82% and a high return on capital employed (ROCE) of 23.43%, the recent negative operating profits and falling participation from institutional investors, who have reduced their stake by 1.55%, have contributed to the stock's decline. The stock's liquidity remains adequate for trading, but the overall sentiment appears to be bearish, especially given its substantial underperformance relative to the market over the past year.
