Why is Solitaire Mach. falling/rising?

As of 19-Sep, Solitaire Machine Tools Ltd is experiencing a decline in its stock price, currently at 126.50, which reflects a decrease of 1.0 or 0.78%. The stock has shown a mixed performance today, trading flat with no range movement since opening. While it has outperformed the benchmark Sensex over various periods, including a 26.56% return over the past year compared to the Sensex's -0.67%, the stock's recent performance is overshadowed by weak long-term fundamentals. The company has reported a significant drop in net sales and poor profitability metrics, including a low return on equity of 9.45% and a concerning EBIT to Interest ratio of 1.90, indicating challenges in servicing its debt. Additionally, a decline in investor participation, with delivery volume falling by 25.13%, further contributes to the stock's downward pressure.
In the broader market context, the stock's recent performance aligns with a generally positive trend in the market, as indicated by the Sensex's 0.88% gain over the past week. However, despite the stock's strong historical returns, its current valuation appears expensive compared to peers, with a PEG ratio of 5.5. This suggests that while the stock has been able to generate returns, the underlying financial health and growth prospects are raising concerns among investors, leading to its current price decline.
