Why is Epack Durable falling/rising?

As of 18-Sep, Epack Durable Ltd's stock price is currently at 389.10, reflecting a decrease of 1.1, or 0.28%. Today's price summary indicates that the stock has underperformed its sector by 1.22%. Despite a positive trend in investor participation, with delivery volume rising by 85.5% against the 5-day average, the stock's performance over the past year shows a modest return of 1.30%, while it has experienced a significant year-to-date decline of 29.34%. The company has reported healthy long-term growth, with net sales increasing at an annual rate of 33.30%, and positive quarterly results showing substantial growth in profit before tax and net sales. However, the low return on capital employed (ROCE) of 8.32% and a high enterprise value to capital employed ratio suggest expensive valuation and poor management efficiency, which may be contributing to the stock's downward movement.
In the broader market context, Epack Durable's short-term return of 2.57% over the past week outperforms the Sensex, which has returned 1.80% in the same period. However, the company's declining institutional investor participation, with a decrease of 2.19% in stakes held, indicates a lack of confidence from more sophisticated investors who typically have better resources for analyzing company fundamentals. This decline in institutional support, combined with the stock's underperformance relative to its sector and the broader market, may be influencing investor sentiment negatively, contributing to the current price decline.
