Why is S & T Corporatio falling/rising?

As of 23-Sep, S & T Corporation Ltd is experiencing a price increase, with its current price at 5.56, reflecting a change of 0.43 or 8.38% upward. The stock has outperformed its sector by 9.3% today, and its performance over the past week shows a gain of 4.51%, while it has increased by 2.96% over the past month. However, despite this recent uptick, the stock's year-to-date performance remains significantly negative at -40.85%, and it has declined by 66.90% over the past year. Additionally, the stock's delivery volume has decreased by 44.42% compared to the five-day average, indicating a falling investor participation, which could impact future price movements.
In the broader market context, the Sensex has shown a slight decline of 0.34% over the past week, contrasting with S & T Corporation's positive short-term return. While the stock has been liquid enough for trading, its moving averages indicate that it is performing better than the 5-day and 20-day averages but is still below the longer-term averages of 50, 100, and 200 days. This suggests that while there is some short-term momentum, the stock's long-term performance remains weak compared to the benchmark, which has increased by 5.07% year-to-date.
