Why is Epack Durable falling/rising?

As of 14-Aug, Epack Durable Ltd's stock price is currently at Rs 364.00, reflecting a decline of Rs 12.0 or 3.19%. Today's performance indicates that the stock has underperformed its sector by 3.87%, with an intraday low of Rs 361.45. The stock has experienced a significant drop in investor participation, with delivery volume falling by 84.73% compared to the 5-day average. Over the past week, the stock has decreased by 6.58%, while it has shown a modest increase of 0.78% over the past month. Despite a strong annual growth in net sales and impressive quarterly earnings, the company's low return on capital employed (ROCE) of 8.32% and high valuation metrics suggest underlying profitability issues, contributing to the stock's downward movement.
In the broader market context, Epack Durable's recent performance contrasts sharply with the benchmark Sensex, which has remained relatively stable with a decline of only 0.03% over the past week. While the stock has outperformed the market over the past year with a return of 54.17%, the current trend indicates a lack of confidence among institutional investors, who have reduced their stakes by 2.19%. This decline in institutional interest, coupled with the company's expensive valuation and low management efficiency, may be influencing the stock's negative trajectory despite its historical growth performance.
