Why is Solitaire Mach. falling/rising?

As of 17-Sep, Solitaire Machine Tools Ltd is experiencing a decline in its stock price, currently at Rs 126.50, reflecting a decrease of Rs 1.45 or 1.13%. Today's price summary indicates that the stock has underperformed its sector by 1.36%, following a trend reversal after three consecutive days of gains. The stock opened with a loss of 2.27% and reached an intraday high of Rs 135 before falling to a low of Rs 125.05. Despite a strong year-to-date return of 15.84% and a one-year return of 25.98%, the company faces challenges, including weak long-term fundamentals, a poor EBIT to Interest ratio, and flat results in recent quarters, which may be contributing to the current price decline.
In the broader market context, the stock's short-term performance has lagged behind the benchmark Sensex, which has gained 1.56% over the past week and 2.60% over the past month. While the stock has outperformed the market over the past year, its recent underperformance and declining investor participation, evidenced by a significant drop in delivery volume, suggest that investor sentiment may be shifting negatively. The company's high valuation relative to its peers, coupled with weak growth indicators, further complicates its outlook, leading to a cautious market response.
