Why is Apcotex Industri falling/rising?

As of 15-Sep, Apcotex Industries Ltd is experiencing a decline in its stock price, currently at Rs 408.00, which represents a decrease of Rs 10.4 or 2.49%. The stock has underperformed its sector by 4.23% today and has fallen after two consecutive days of gains. It reached an intraday low of Rs 397.3, reflecting a drop of 5.04%. Over the past week, the stock has shown a slight decline of 0.23%, while its one-year performance indicates a more significant drop of 8.14%. Despite this recent downturn, the company has demonstrated strong fundamentals, including a low Debt to EBITDA ratio of 0.64 times and impressive growth in net sales and operating profit, which may provide some support for the stock's valuation.
In the broader market context, the Sensex has increased by 1.24% over the past week, contrasting with Apcotex's slight decline. Although the stock has shown a positive year-to-date return of 9.03%, its three-year performance is notably poor, with a decline of 29.36% compared to the Sensex's gain of 36.46%. This underperformance in the long term may be contributing to the current selling pressure. Additionally, while the stock is trading at a discount compared to its peers, the recent price movement suggests that investor sentiment may be cautious, particularly in light of today's performance and the overall market trends.
