Why is Epack Durable falling/rising?

As of 11-Aug, Epack Durable Ltd's stock price is currently at Rs 378.60, experiencing a decline of Rs 16.4, which represents a 4.15% decrease. Today's price summary indicates that the stock has underperformed its sector by 0.87% and has seen a trend reversal after two consecutive days of gains. The stock touched an intraday low of Rs 373.5, reflecting a drop of 5.44%. Over the past week, the stock has decreased by 0.86%, while it has shown a positive return of 2.82% over the past month. Despite a strong year-on-year performance of 57.10%, the company faces challenges such as poor management efficiency with a low return on capital employed (ROCE) of 8.32% and a decline in institutional investor participation, which has decreased by 2.19% in the previous quarter.
In the broader market context, the Sensex has decreased by 0.51% over the past week, indicating that Epack Durable's short-term performance is slightly worse than the benchmark. While the stock has outperformed the market over the past year, the recent decline in institutional interest and the company's expensive valuation relative to its profitability may be contributing to the current downward pressure on the stock price. Additionally, the air conditioning sector, in which the company operates, has also seen a decline of 3.31%, further impacting investor sentiment.
