Why is S & T Corporatio falling/rising?

As of 20-Oct, S & T Corporation Ltd's stock price is currently at 5.95, reflecting an increase of 0.27 or 4.75%. The stock has shown strong performance in the short term, with a 1-week return of +11.21% and a 1-month return of +12.90%, significantly outperforming the Sensex, which has returned +2.47% and +2.10% over the same periods, respectively. However, despite today's positive movement, the stock has experienced a notable decline year-to-date of -36.70% and a staggering -56.51% over the past year. Today's price summary indicates that the stock is performing better than its sector by 4.02%, but there is a concerning trend of falling investor participation, as evidenced by a -33.73% drop in delivery volume compared to the 5-day average.
In the broader market context, while S & T Corporation has outperformed the benchmark in the short term, the long-term performance remains significantly negative, with a 3-year decline of -87.94% compared to the Sensex's +42.50%. This stark contrast highlights the challenges the company faces in regaining investor confidence. Additionally, the stock's liquidity is adequate for trading, but the fact that it is trading below its 200-day moving average suggests potential concerns about its long-term viability. Overall, the combination of recent positive short-term performance and ongoing long-term struggles creates a complex picture for investors.
