Why is HPCL falling/rising?

As of 04-Sep, Hindustan Petroleum Corporation Ltd. is experiencing a decline in its stock price, currently at 384.50, which reflects a decrease of 2.7 or 0.7%. The stock has shown mixed performance in recent periods, with a 1-week return of +0.73% but a significant 1-month decline of -5.92%. Today's price summary indicates that while the stock outperformed its sector by 0.3%, it is trading below several moving averages, specifically the 20-day, 50-day, and 100-day averages. Additionally, there has been a notable decrease in investor participation, with delivery volume falling by 14.46% against the 5-day average. Despite these challenges, the company has demonstrated healthy long-term growth, with net sales increasing at an annual rate of 12.82% and operating profit at 26.09%. High institutional holdings at 36.72% suggest confidence in the company's fundamentals, as these investors have increased their stake by 0.6% over the previous quarter.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has seen a slight increase of 0.80% over the past week. While HPCL's 1-year return is down by 13.50%, the benchmark has only declined by 1.98%, indicating that the stock is underperforming relative to the market. This underperformance may be attributed to the stock's current valuation, which, despite being attractive compared to peers, has not translated into positive price movement. The company's recent positive financial results, including the highest quarterly PBDIT and operating profit margins, highlight its operational strength, but this has not yet led to a recovery in stock price, reflecting broader market sentiments and investor caution.
