Why is Solitaire Mach. falling/rising?

As of 18-Sep, Solitaire Machine Tools Ltd is experiencing a price increase, currently at 127.50, reflecting a change of 1.0 or 0.79% upward. The stock has shown strong performance, outperforming the sector by 0.39% today. Over the past week, it has risen by 2.25%, and in the last month, it has increased by 2.82%. Despite a weak long-term fundamental strength indicated by a low average Return on Equity (ROE) of 9.45% and flat results in recent quarters, the stock has managed to generate a notable return of 26.30% over the past year, significantly outperforming the BSE500, which has seen negative returns of -1.96%. However, concerns about the company's ability to service its debt and its expensive valuation compared to peers may temper investor enthusiasm.
In the broader market context, the stock's recent performance has been favorable compared to the benchmark, with a 1-week return of 2.25% against the Sensex's 1.80% and a year-to-date return of 16.76% compared to the benchmark's 6.24%. This indicates that while the stock is rising, it is doing so in a market environment that has been relatively weak overall. The rising investor participation, evidenced by a significant increase in delivery volume, suggests growing interest in the stock, which may be contributing to its upward price movement despite the underlying concerns regarding its long-term fundamentals.
