Why is Mamata Machinery falling/rising?

As of 12-Sep, Mamata Machinery Ltd's stock price is currently at Rs 454.50, reflecting a decline of Rs 9.4 or 2.03%. The stock has been underperforming recently, having fallen consecutively for the last two days, resulting in a total decrease of 5.06%. Despite touching an intraday high of Rs 473.45, it also reached a low of Rs 446.35 today. Over the past week, the stock has shown a positive return of 12.08%, but it has significantly underperformed the sector by 2.94%. The company has a low Debt to Equity ratio of 0.04, indicating financial stability, and its operating profit has grown at an impressive annual rate of 85.43%. However, the recent quarterly results have been disappointing, with net sales falling by 39.3% and profit before tax declining by 82.8% compared to previous averages, contributing to the stock's negative movement.
In the broader market context, while Mamata Machinery has experienced a short-term gain of 12.08% over the past week, the benchmark Sensex has only increased by 1.48% during the same period, indicating a relative strength in the stock's performance. However, the year-to-date performance shows a stark contrast, with the stock down 20.07% compared to the Sensex's gain of 4.82%. Additionally, there has been a notable decrease in institutional investor participation, with a reduction of 0.84% in their stakes, which may signal a lack of confidence in the stock's future prospects. This combination of poor quarterly results and declining institutional interest likely contributes to the stock's current downward trend.
