Why is APM Industries falling/rising?

As of 09-Sep, APM Industries Ltd is experiencing a decline in its stock price, currently at 33.00, reflecting a decrease of -0.41 or -1.23%. The stock has underperformed its sector by -1.25% today and has been on a consecutive downward trend for the last two days, with a total drop of -1.26% in that period. Additionally, the stock's performance over the past month shows a significant decline of -5.85%, and it has generated a staggering -38.60% return year-to-date. The company's fundamentals are weak, highlighted by a -185.01% CAGR growth in operating profits over the last five years and a negative profit after tax of Rs -0.62 crore in the latest quarter. The falling investor participation, with a delivery volume drop of -81.6% against the 5-day average, further indicates a lack of confidence among investors.
In the broader market context, APM Industries' short-term performance has lagged behind the benchmark, with the Sensex showing a positive return of +1.18% over the past week while APM Industries only managed a gain of +1.04%. This consistent underperformance against the benchmark, particularly over the last three years, where the stock has generated -41.09% returns compared to a slight decline of -0.56% for the Sensex, underscores the challenges the company faces. The low return on equity of 5.66% and the negative operating profits signal a risky investment environment, contributing to the stock's downward movement.
