Why is HPCL falling/rising?

As of 05-Sep, Hindustan Petroleum Corporation Ltd. is experiencing a decline in its stock price, currently at 383.95, reflecting a decrease of 0.55 or 0.14%. The stock has underperformed its sector today by 0.88% and has been on a consecutive downward trend for the last two days, resulting in a total return drop of 0.84% during this period. Over the past week, the stock has shown a modest gain of 1.98%, but it has underperformed significantly over the last month with a decline of 4.56%. Despite a healthy long-term growth outlook, with net sales growing at an annual rate of 12.82% and operating profit at 26.09%, the stock has generated a negative return of 14.48% over the past year, indicating a challenging environment for the company.
In the broader market context, while the Sensex has remained flat with a 0.00% return over the last month, HPCL's performance has been notably weaker, highlighting its struggles relative to the benchmark. The stock's recent performance is further compounded by its underperformance in the last year, where it fell by 14.48% compared to the market's decline of only 1.81%. Although there is rising investor participation and high institutional holdings, which suggest confidence in the company's fundamentals, the overall negative sentiment and recent price movements indicate that investors are cautious, leading to the current decline in HPCL's stock price.
