Why is Epack Durable falling/rising?

As of 06-Oct, Epack Durable Ltd's stock price is currently at Rs 346.00, reflecting a decrease of Rs 11.35 or 3.18%. The stock has underperformed its sector today by 3.26% and has experienced a trend reversal, falling after two consecutive days of gains. It reached an intraday low of Rs 345.05, indicating a decline of 3.44%. The stock has shown significant underperformance over various periods, with a 1-month return of -13.46% and a year-to-date return of -37.17%. Additionally, the company's management efficiency is a concern, as evidenced by a low Return on Capital Employed (ROCE) of 8.32%, which suggests low profitability relative to its capital. Despite healthy long-term growth in net sales, the stock's valuation appears expensive, contributing to its recent decline.
In the broader market context, Epack Durable's performance has lagged behind the Sensex, which has gained 1.77% over the past week while Epack Durable has lost 1.83%. The stock's consistent underperformance against the benchmark over the last three years, coupled with a decrease in institutional investor participation, further exacerbates its challenges. Institutional investors have reduced their stakes by 2.19%, indicating a lack of confidence in the stock's fundamentals. This combination of poor short-term performance, weak management efficiency, and declining investor interest has contributed to the stock's downward trajectory.
