Why is Grill Splendour falling/rising?

As of 15-September, Grill Splendour Services Ltd is experiencing a decline in its stock price, currently at 125.00, which reflects a decrease of 3.2 points or 2.5%. Despite this drop, the stock has shown strong performance over the past week and month, with returns of 4.17% and 3.31%, respectively. Year-to-date, the stock has surged by 50.42%, significantly outperforming the Sensex, which has only increased by 6.02% during the same period. Today's performance indicates that the stock has underperformed its sector by 3.71%. Additionally, while the stock is trading above its 5-day, 20-day, 100-day, and 200-day moving averages, it is currently below its 50-day moving average. Notably, there has been a substantial increase in investor participation, with delivery volume rising by 600% against the 5-day average, suggesting heightened interest despite the current price decline.
In the broader market context, Grill Splendour's recent short-term performance has outpaced the Sensex, which has only gained 1.20% over the past week. This indicates that while the stock is facing a temporary setback, its overall trajectory remains strong compared to the benchmark. The liquidity of the stock is also favorable, as it is liquid enough for trading sizes, which may help stabilize its price in the face of recent fluctuations. However, without specific positive or negative factors available, it is challenging to pinpoint the exact reasons behind the current price movement beyond the observed trends and investor behavior.
