Why is Grill Splendour falling/rising?

As of 12-Sep, Grill Splendour Services Ltd is experiencing a price increase, currently at 128.20, reflecting a change of 4.1 or 3.3% upward. The stock has shown strong performance, outperforming its sector by 3.23% today. It is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bullish trend. Over the past week, the stock has risen by 6.83%, and year-to-date, it has gained an impressive 54.27%. However, there has been a decline in investor participation, with delivery volume dropping by 16.67% compared to the 5-day average, which may raise concerns about the sustainability of this upward movement.
In the broader market context, Grill Splendour's short-term performance significantly outpaces the benchmark Sensex, which has only increased by 1.51% over the past week. This strong relative performance highlights investor confidence in Grill Splendour compared to the overall market. Despite the positive price movement, the decline in delivery volume suggests that while the stock is currently rising, there may be underlying factors that could affect its momentum if investor participation does not improve.
