Why is HPCL falling/rising?

As of 29-Aug, Hindustan Petroleum Corporation Ltd. is experiencing a decline in its stock price, currently at 376.50, reflecting a decrease of 5.2 points or 1.36%. The stock has been on a downward trend, losing value for the last five consecutive days, resulting in a total decline of 4.13% during this period. Additionally, it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Despite this, the stock has outperformed its sector by 0.25% today, and there has been a notable increase in delivery volume, which rose by 26.22% compared to the 5-day average. Over the past week, HPCL has seen a return of -3.57%, while its performance over the last month is down by 11.53%.
In the broader market context, HPCL's recent performance contrasts with the Sensex, which has declined by only 1.84% over the same week and 1.88% over the past month. While the company has demonstrated healthy long-term growth with a 12.82% annual increase in net sales and a significant rise in operating profit, these positive factors have not translated into short-term stock performance. The stock's valuation remains attractive, trading at a discount compared to peers, and institutional holdings are high at 36.72%, indicating confidence from larger investors. However, the stock's negative returns over the past year, coupled with a high PEG ratio of 2.4, suggest that investors may be cautious, contributing to its current price decline.
