Why is C P C L falling/rising?

As of 24-Jul, Chennai Petroleum Corporation Ltd's stock price is currently at Rs 761.00, reflecting a decrease of Rs 14.15 or 1.83%. The stock has been underperforming, having lost 3.3% over the last two days, and it touched an intraday low of Rs 756.15. Despite a positive performance over the past month with a return of 10.94%, the stock has significantly underperformed over the past year, with a decline of 25.12%. The recent drop in delivery volume by 40.97% against the 5-day average indicates falling investor participation, which may be contributing to the stock's downward movement. Additionally, while the company has shown high management efficiency and healthy long-term growth, recent financial results have been disappointing, with a 50.59% decline in PAT over the last six months and a low ROCE of 4.35%.
In the broader market context, the stock's short-term performance of +2.11% over the past week contrasts with the Sensex, which has seen a slight decline of 0.09%. However, the stock's longer-term performance is concerning, as it has underperformed the market significantly over the past year, while the BSE500 index has generated a return of 0.99%. The decrease in institutional investor participation, with a reduction of 1.55% in their stake, further suggests a lack of confidence in the stock's prospects, which may be influencing its current price decline.
