Why is Epack Durable falling/rising?

As of 12-Aug, Epack Durable Ltd's stock price is currently at 374.95, reflecting a decrease of 3.65, or 0.96%. The stock has been underperforming, having lost 5.08% over the last two days and showing a 2.79% decline over the past week, while it has gained 1.83% in the last month. Despite a strong long-term growth trajectory with net sales increasing at an annual rate of 33.30%, the company faces challenges such as poor management efficiency indicated by a low Return on Capital Employed (ROCE) of 8.32%. Additionally, there has been a notable decline in investor participation, with delivery volume falling by 24.79% against the five-day average, which may contribute to the stock's downward pressure.
In the broader market context, Epack Durable's recent performance contrasts with the benchmark Sensex, which has only declined by 0.59% over the past week. While the stock has outperformed the market over the past year with a return of 50.01% compared to the Sensex's 0.74%, the recent trend suggests a shift in sentiment, particularly with institutional investors reducing their stake by 2.19%. This decline in institutional interest, coupled with the stock's expensive valuation relative to its profitability, may be influencing the current downward movement in Epack Durable's stock price.
