Why is Solitaire Mach. falling/rising?

As of 19-Aug, Solitaire Machine Tools Ltd is experiencing a slight increase in its stock price, currently at 124.50, reflecting a change of 0.5 or 0.4% upward. Despite this minor uptick, the stock has underperformed its sector by 0.59% today. Over the past week, it has shown a positive return of 3.49%, while its performance over the last month has been significantly negative at -22.65%. The stock's recent performance is concerning, as it has seen a drastic decline in delivery volume, down 93.55% compared to the 5-day average, indicating falling investor participation. Additionally, while the stock has generated a notable return of 30.16% over the past year, its long-term fundamentals are weak, with a low average Return on Equity (ROE) of 9.45% and poor growth in net sales and operating profit.
Broader market context shows that while the Sensex has gained 1.76% over the past week, Solitaire Machine Tools Ltd has outperformed it in this timeframe. However, the stock's year-to-date performance of +14.01% and 3-year performance of +97.93% suggest a strong historical trend, contrasting with its recent struggles. The broader market has faced negative returns, yet the stock's ability to generate substantial returns in the past year highlights its potential. Nevertheless, the company's weak fundamentals, including a poor EBIT to Interest ratio and an expensive valuation compared to peers, raise concerns about its sustainability in the face of market fluctuations.
