Why is Epack Durable falling/rising?

As of 04-Sep, Epack Durable Ltd's stock price is currently at Rs 388.85, reflecting a decrease of Rs 9.85 or 2.47%. The stock has recently underperformed its sector by 0.61% and has experienced a trend reversal, falling after four consecutive days of gains. Although it opened with a gain of 2.66% today and reached an intraday high of Rs 409.3, it also touched a low of Rs 387, indicating volatility. Over the past week, the stock has shown a positive return of 3.58%, while its year-to-date performance remains negative at -29.39%. Despite a strong annual growth in net sales of 33.30% and impressive quarterly results, the stock faces challenges such as poor management efficiency, indicated by a low return on capital employed (ROCE) of 8.32%, and a decline in institutional investor participation.
In the broader market context, while the stock has generated a remarkable return of 52.16% over the past year, the benchmark Sensex has only returned -1.98% in the same period. However, the stock's year-to-date performance significantly lags behind the benchmark, which has gained 3.30%. This discrepancy highlights the stock's volatility and the potential concerns surrounding its management efficiency and valuation, which may be contributing to its recent price decline. The falling participation from institutional investors, who have reduced their stake by 2.19%, further suggests a lack of confidence in the stock's future performance, impacting its current price movement.
