Why is Ashish Polyplast falling/rising?

As of 16-Sep, Ashish Polyplast Ltd's stock price is currently at Rs 43.40, reflecting an increase of Rs 4.3 or 11.0%. The stock has shown strong performance recently, gaining 18.77% over the last three days and outperforming its sector by 9.83% today. It opened with a significant gap up of 17.65% and reached an intraday high of Rs 46. Despite this positive short-term movement, the company has a weak long-term fundamental strength, indicated by a low Return on Capital Employed (ROCE) of 4.30% and a concerning EBIT to Interest ratio of 0.27. Additionally, the stock has underperformed over the past year with a return of -27.40%, while its profits have decreased by -65%.
In the broader market context, Ashish Polyplast's short-term return of +20.56% over the past month significantly outpaces the Sensex's +2.21% return during the same period. However, the stock's year-to-date performance remains poor at -19.63%, contrasting with the Sensex's +5.43%. This disparity highlights the stock's volatility and the potential impact of recent investor participation, as evidenced by a 329.41% increase in delivery volume. While the stock's recent gains may attract attention, its long-term challenges and high valuation relative to peers suggest caution for investors.
