Why is Sellwin Traders falling/rising?

As of 20-Jun, Sellwin Traders Ltd is experiencing a price increase, currently at 5.30, reflecting a change of 0.14 or 2.71% upward. The stock has shown strong performance recently, gaining 27.1% over the last six days and outperforming its sector by 1.14% today. In terms of returns, the stock has risen significantly over the past week by 24.41% and by 62.58% over the past month, although it has a concerning long-term performance with a 1-year return of -79.07%. The stock's liquidity appears adequate, with a notable increase in delivery volume, which rose by 262.64% compared to the 5-day average. However, the company faces challenges, including weak long-term fundamentals indicated by a low Return on Equity (ROE) of 4.02% and a high Price to Book Value ratio of 1.9, suggesting it is trading at a premium relative to its peers.
In the broader market context, while Sellwin Traders has outperformed the Sensex in the short term, the benchmark index has only gained 1.59% over the past week, highlighting the stock's strong momentum relative to the market. Despite this recent surge, the stock has significantly underperformed over the past year compared to the broader market, which has generated a return of 2.60%. This stark contrast between short-term gains and long-term underperformance may create skepticism among investors regarding the sustainability of the current price rise.
