Why is C P C L falling/rising?

As of 05-Sep, Chennai Petroleum Corporation Ltd's stock price is rising, currently at 702.20, with an increase of 10.7 (1.55%). The stock has shown a positive trend today, outperforming its sector by 0.81% and reversing a two-day decline. It is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a strong upward momentum. Over the past week, the stock has gained 8.72%, and it has also performed well over the past month with a return of 9.62%. However, there are concerns regarding falling investor participation, as the delivery volume has decreased significantly, and the stock has faced negative results in recent quarters, including a substantial drop in profits.
In the broader market context, while the stock has outperformed the Sensex in the short term, gaining 8.72% compared to the benchmark's 1.13% over the past week, it has underperformed over the last year, with a return of -28.19% against the Sensex's -1.81%. This underperformance highlights the stock's volatility and the risks associated with it, particularly given the negative operating profits and decreasing institutional investor participation. Despite the company's high management efficiency and healthy long-term growth in net sales, the recent financial struggles and falling institutional interest may weigh on investor sentiment moving forward.
