Why is Polymac Thermof. falling/rising?

As of 17-Sep, Polymac Thermoformers Ltd is experiencing a price increase, with its current price at 20.31, reflecting a change of 0.93 or 4.8% upward. The stock has shown a strong performance today, outperforming its sector by 5.41%. However, it has exhibited erratic trading patterns, not trading on 4 out of the last 20 days. Despite being higher than the 5-day, 20-day, 50-day, and 100-day moving averages, it remains below the 200-day moving average. Additionally, there has been a notable decline in investor participation, with delivery volume on September 15 falling by 44.44% compared to the 5-day average. The stock's year-to-date return stands at 3.36%, which is lower than the benchmark Sensex's return of 5.83% for the same period.
In the broader market context, Polymac's short-term return of 9.72% over the past week significantly outpaces the Sensex's return of 1.56%, indicating strong relative performance. However, the stock's longer-term performance reveals a decline of 6.41% over the past year, contrasting with the Sensex's slight decrease of 0.46%. This suggests that while the stock is currently rising, it has faced challenges in the past year and over the last three years, where it has decreased by 43.97%, while the benchmark has increased by 40.54%. The mixed performance signals that while there may be short-term gains, the stock's long-term trajectory remains a concern for investors.
