Why is United Polyfab falling/rising?

As of 31-Jul, United Polyfab Gujarat Ltd's stock price is rising, currently at 30.48, reflecting an increase of 1.45 or 4.99%. The stock has shown strong performance in the short term, with a 27.27% increase over the past week and a 45.70% rise over the past month, significantly outperforming the Sensex, which has declined by 1.17% and 3.03% respectively during those periods. Today's price summary indicates that the stock has outperformed its sector by 7.34%. However, there are concerns regarding falling investor participation, as the delivery volume has decreased by 13.06% compared to the 5-day average. The company has reported positive results for the last three consecutive quarters, with substantial growth in profit before tax and profit after tax, which may have contributed to the recent price increase.
In the broader market context, while United Polyfab has shown impressive short-term returns, it has underperformed in the long term, with a year-to-date decline of 81.30% and a one-year return of -64.96%, contrasting with the Sensex's gain of 4.75% over the same period. The stock's long-term fundamental strength is weak, evidenced by a negative CAGR growth in net sales over the last five years and a high debt-to-EBITDA ratio. Additionally, the lack of domestic mutual fund investment may indicate a lack of confidence in the stock's valuation, despite its recent positive quarterly results. This mixed performance suggests that while the stock is currently rising, underlying concerns about its long-term viability remain.
