Why is Atmastco Ltd falling/rising?

As of 22-Sep, Atmastco Ltd's stock price is currently at 215.80, reflecting an increase of 4.8, or 2.27%. The stock has outperformed its sector today by 2.77%, although it is trading higher than its 5-day and 100-day moving averages, but lower than its 20-day, 50-day, and 200-day moving averages. Over the past week, the stock has shown a positive return of 5.47%, contrasting with a significant decline of 14.42% over the past month. Additionally, there has been a notable decrease in investor participation, with delivery volume dropping by 50.19% compared to the 5-day average, indicating a potential concern regarding sustained interest in the stock. Unfortunately, the positive and negative factors impacting the stock's movement are not available.
Broader market context shows that while Atmastco Ltd has experienced a short-term gain, its performance over the longer term has been less favorable, with a year-to-date decline of 20.97% compared to a 6.59% increase in the benchmark Sensex. The stock's recent performance is particularly noteworthy given that it has outperformed the Sensex by a significant margin in the short term, suggesting that the recent price increase may be driven by specific factors related to the company rather than broader market trends.
