Why is Premier Energies falling/rising?

As of 18-Sep, Premier Energies Ltd is experiencing a decline in its stock price, currently at 1,052.45, which represents a decrease of 25.45 or 2.36%. The stock has underperformed its sector by 1.9% today and has been on a downward trend for the last two days, accumulating a total drop of 2.85% during this period. The stock touched an intraday low of Rs 1050.3 and has seen a significant decrease in delivery volume, falling by 51.6% against the 5-day average. Despite the company's strong long-term fundamentals, including a robust average Return on Equity (ROE) of 33.21% and impressive growth in net sales and operating profit, these positive factors have not translated into immediate stock price support.
In the broader market context, the stock's performance over the past week shows a decline of 1.34%, while the benchmark Sensex has increased by 1.80%. Year-to-date, Premier Energies has underperformed significantly, with a decline of 22.19% compared to the Sensex's gain of 6.24%. The recent increase in institutional investor participation, which has risen by 5.73% over the previous quarter, indicates a positive outlook from more knowledgeable investors, but this has not yet positively impacted the stock's short-term performance. Overall, the combination of recent price declines, reduced trading volume, and underperformance relative to the benchmark suggests a challenging environment for Premier Energies Ltd at this time.
