Why is Epic Energy falling/rising?

As of 19-Sep, Epic Energy Ltd's stock price is currently at 50.14, reflecting a decrease of 1.91, or 3.67%. The stock has recently underperformed its sector by 5.59% and has experienced a trend reversal after four consecutive days of gains. Although it opened with a gain of 5% today, reaching an intraday high of Rs 54.65, it subsequently fell to a low of Rs 49.71, indicating volatility. The stock's year-to-date performance shows a significant decline of 57.00%, despite a strong three-year return of 494.08%. Additionally, there has been a notable drop in investor participation, with delivery volume falling by 50.64% compared to the five-day average, which may have contributed to the downward pressure on the stock price.
Broader market context indicates that while the Sensex has increased by 0.88% over the past week, Epic Energy's stock has risen by 15.26% in the same period, showcasing a strong short-term performance relative to the benchmark. However, the stock's one-month performance is slightly negative at -0.42%, contrasting with the Sensex's positive return of 1.20%. This suggests that while the stock has had a brief surge, it is struggling to maintain momentum in the longer term, particularly given its substantial year-to-date decline compared to the benchmark's gain of 5.74%.
