Why is HPCL falling/rising?

As of 22-Jul, Hindustan Petroleum Corporation Ltd. is experiencing a decline in its stock price, currently at 429.05, reflecting a decrease of 3.75 or 0.87%. The stock's performance today is in line with the sector, although it has shown a decrease in delivery volume, which fell by 27.82% compared to the 5-day average. Despite this short-term decline, the stock has demonstrated strong long-term growth, with net sales increasing at an annual rate of 10.06% and operating profit at 35.33%. The company has a high dividend yield of 3.81% and is trading at a discount compared to its peers, which may attract long-term investors. However, it is important to note that while the stock has generated a return of 23.72% over the past year, its profits have decreased by 57.9%, which could be a concern for investors.
In the broader market context, the stock's 1-week return of -1.08% is underperforming compared to the Sensex, which has decreased by only 0.47% during the same period. This suggests that the stock's recent decline is not solely due to market conditions but may also be influenced by company-specific factors. Despite the short-term challenges, the stock has outperformed the benchmark over longer periods, including a 4.90% increase year-to-date and a remarkable 177.45% rise over the last three years. High institutional holdings at 36.12% indicate confidence from larger investors, which could provide some stability amidst the current fluctuations.
