Why is United Polyfab falling/rising?

As of 29-Jul, United Polyfab Gujarat Ltd's stock price is currently at 27.65, reflecting an increase of 1.31, or 4.97%. The stock has shown strong performance recently, with a 27.07% increase over the past week and a remarkable 40.71% rise over the past month, significantly outperforming the Sensex, which has declined by 0.96% and 3.19% in the same periods, respectively. However, despite this recent surge, the stock has experienced a substantial decline of 83.04% year-to-date and 68.39% over the past year. Positive factors contributing to the stock's recent rise include the company's strong quarterly results, with a 110.42% growth in profit before tax and a staggering 3100% increase in profit after tax over the last three quarters. Conversely, the stock faces challenges such as weak long-term fundamental strength, a high debt-to-EBITDA ratio, and low domestic mutual fund participation, which may indicate a lack of confidence in the stock's valuation.
In the broader market context, United Polyfab's recent performance stands in stark contrast to the benchmark, as it has outperformed the Sensex significantly in the short term while the benchmark has struggled. The stock's liquidity remains adequate for trading, although there has been a notable decline in investor participation, with delivery volume falling by 45.69% against the five-day average. This decline in participation, coupled with the company's long-term underperformance and high valuation metrics, suggests that while the stock is currently rising, there are underlying concerns that could affect its sustainability in the future.
