Why is Menon Pistons falling/rising?

As of 23-Sep, Menon Pistons Ltd is experiencing a price increase, currently at Rs 68.50, which reflects a rise of Rs 2.12 or 3.19%. Today's performance indicates a positive trend as the stock has outperformed its sector by 2.69% and has gained after four consecutive days of decline. The stock reached an intraday high of Rs 69.5, showing a 4.7% increase. Despite a one-week return of -1.74%, the stock has performed better over the past month with a return of +4.58%. The company has shown high management efficiency with a return on equity (ROE) of 17.80% and a low debt-to-equity ratio of 0.07 times. Additionally, it reported positive results in June 2025 after two negative quarters, which may have contributed to the recent price movement.
In the broader market context, while the Sensex has seen a slight decline of -0.34% over the past week, Menon Pistons' performance has been relatively stronger in the same timeframe. However, the stock has underperformed the market over the last year, with a return of -21.01% compared to the Sensex's -3.33%. This suggests that while there may be short-term positive movements, the stock's long-term growth prospects remain a concern due to its poor performance relative to the market and modest growth rates in net sales and operating profit over the past five years.
