Why is Master Trust falling/rising?

As of 17-Sep, Master Trust Ltd's stock price is currently at 144.00, reflecting a decrease of 1.85, or 1.27%. The stock has underperformed its sector today by 1.21%, and it is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend. Over the past week, the stock has declined by 2.93%, and it has experienced a significant drop of 12.25% over the past month. Despite a strong long-term fundamental strength with an average Return on Equity (ROE) of 18.73% and healthy growth in net sales and operating profit, the stock has faced negative results in its latest quarterly performance, with declines in profit before tax, profit after tax, and net sales compared to previous quarters. This has contributed to a year-to-date decline of 11.85% and a one-year drop of 21.81%, significantly underperforming the market.
In the broader market context, the Sensex has shown a positive return of 1.56% over the past week and a 2.60% increase over the past month, contrasting sharply with Master Trust's negative performance. The stock's decline is further exacerbated by its substantial underperformance relative to the BSE500, which has only fallen by 2.63% over the past year. While there has been rising investor participation, as indicated by a 36.01% increase in delivery volume, the overall sentiment remains negative due to the company's recent financial results and its inability to keep pace with market benchmarks.
