Why is ACS Tech falling/rising?

As of 13-Aug, ACS Technologies Ltd is experiencing a price increase, with its current price at 24.17, reflecting a rise of 0.47 or 1.98%. The stock has shown strong performance recently, gaining 5.32% over the last three days and outperforming its sector by 1.64% today. Additionally, ACS Tech has outperformed the benchmark Sensex over the past week and month, with returns of +2.98% and +4.72%, respectively. However, there has been a notable decline in investor participation, as the delivery volume on 12 August fell by 57.34% compared to the five-day average, which could indicate a potential concern for future trading activity.
In the broader market context, while ACS Technologies has been performing well, the Sensex has remained relatively flat, with a slight decline of 0.01% over the past week and a more significant drop of 2.38% over the past month. This contrast highlights the stock's resilience and ability to attract investor interest despite a challenging market environment. The stock is also trading above its moving averages across multiple time frames, suggesting a bullish trend. However, the falling delivery volume may raise questions about the sustainability of this upward momentum in the face of broader market conditions.
