Why is National Plastic falling/rising?

As of 04-Sep, National Plastic Technologies Ltd is experiencing a price increase, currently at Rs 228.50, which reflects a rise of Rs 4.75 or 2.12%. The stock has shown a performance today that outperformed its sector by 2.66%, and it has gained after three consecutive days of decline. Despite being 4.81% away from its 52-week low of Rs 217.5, the stock has a mixed performance over different periods, with a notable decline of 44.23% year-to-date and 41.25% over the past year, while it has significantly outperformed in the longer term with a 189.79% increase over three years and a remarkable 656.62% over five years. The rising investor participation, indicated by a 75.7% increase in delivery volume compared to the five-day average, suggests growing interest in the stock.
In the broader market context, the stock's short-term return of +3.00% over the past week significantly outpaces the Sensex, which has only increased by 0.80% during the same period. This indicates that National Plastic is performing well relative to the overall market, particularly in the short term. However, the stock's year-to-date performance remains concerning compared to the Sensex's gain of 3.30%, highlighting a disparity in long-term performance. Overall, while the stock is currently rising, its historical performance suggests volatility and challenges that investors should consider.
