Why is Polymechplast Ma falling/rising?

As of 27-Jun, Polymechplast Machines Ltd is experiencing a price increase, currently at 65.14, which reflects a change of 5.34 or 8.93% upward. The stock has shown strong performance today, outperforming its sector by 9.6% and achieving a consecutive gain over the last two days with a total return of 10.41%. It opened with a significant gain of 7.02% and reached an intraday high of Rs 68, marking a rise of 13.71%. However, despite these positive short-term movements, the stock has a weak long-term fundamental strength, evidenced by a -31.04% CAGR growth in operating profits over the last five years and a low average return on equity of 8.64%. This suggests that while the stock is currently rising, its underlying profitability remains a concern.
In the broader market context, Polymechplast's short-term return of +9.66% over the past week significantly outpaces the benchmark Sensex, which has only increased by 2.00% during the same period. However, the stock's year-to-date performance is negative at -10.06%, contrasting with the Sensex's positive return of +7.58%. This disparity indicates that while the stock is currently benefiting from short-term momentum, its long-term outlook is less favorable compared to the broader market. Additionally, the falling investor participation, as indicated by a -40.29% drop in delivery volume, may pose challenges for sustaining this upward trend.
