Why is Natl. Plastic falling/rising?

As of 31-Jul, National Plastic Industries Ltd is experiencing a decline in its stock price, currently at 66.36, which reflects a decrease of 2.64 or 3.83%. Today's price summary indicates that the stock underperformed its sector by 3.2%, opening with a significant loss of 4.35% and reaching an intraday low of Rs 65.3, down 5.36%. Additionally, the stock has shown a negative return of 2.98% over the past week and a decline of 4.26% over the past year, despite a positive return of 2.42% over the last month. The falling investor participation is notable, with delivery volume dropping by 58.12% compared to the 5-day average, which may contribute to the stock's downward pressure.
In the broader market context, the Sensex has also seen a decline of 1.22% over the past week, indicating that the stock's short-term performance is worse than the benchmark. Despite the recent price drop, the company has reported positive financial results, with a significant increase in profits and an attractive valuation compared to its peers. The stock is trading at a discount relative to historical valuations, and its profits have risen substantially, suggesting potential for recovery. However, the current negative momentum and reduced trading volume may overshadow these positive factors in the short term.
