Why is National Plastic falling/rising?

As of 22-Sep, National Plastic Technologies Ltd's stock is currently priced at Rs 300.80, reflecting a decrease of Rs 15.8 or 4.99%. The stock has recently experienced a trend reversal, falling after seven consecutive days of gains. Today's performance indicates that it underperformed its sector by 4.29%, and it reached an intraday low of Rs 300.80. Despite this decline, the stock has shown strong performance over the past week and month, with returns of +18.19% and +32.31%, respectively. However, it has a year-to-date decline of -26.58%, indicating a challenging longer-term trend. The stock is trading above its moving averages, suggesting some underlying strength, and there has been a significant increase in investor participation, with delivery volume rising by 82.47% against the five-day average.
In the broader market context, while National Plastic's recent short-term returns have significantly outperformed the Sensex, which only gained 0.46% over the same week, the stock's year-to-date performance contrasts sharply with the benchmark's positive return of 5.15%. This divergence highlights the stock's volatility and the potential for recovery, yet the recent drop may reflect profit-taking after its previous gains. The liquidity of the stock remains adequate for trading, which may provide some support in the face of recent declines. Overall, the combination of short-term gains and longer-term struggles contributes to the current price movement.
