Why is Prime Urban falling/rising?

As of 19-Sep, Prime Urban Development India Ltd is experiencing a price increase, with its current price at Rs. 18.20, reflecting a rise of 0.52 (2.94%). The stock has recently hit a new 52-week high of Rs. 18.5 and has outperformed its sector by 3.4%. Over the past three days, the stock has gained 12.9%, and it is trading above all key moving averages, indicating strong momentum. Additionally, the stock has shown impressive returns, with a 1-year increase of 80.38% and a 3-year increase of 114.62%. However, it is important to note that the company has a negative book value and weak long-term fundamentals, with net sales declining at an annual rate of -35.86% over the last five years.
In the broader market context, Prime Urban's recent performance stands in stark contrast to the Sensex, which has only increased by 0.88% over the past week. The stock's strong short-term performance, coupled with rising investor participation and liquidity, suggests a positive sentiment among investors despite the company's underlying financial challenges. While the stock has generated significant returns, the high debt levels and negative EBITDA indicate potential risks that could affect its long-term viability.
