Why is Atmastco Ltd falling/rising?

As of 10-Sep, Atmastco Ltd's stock price is currently at 223.50, reflecting an increase of 5.6, or 2.57%. Today's price summary indicates that the stock has outperformed its sector by 1.46%. Additionally, there has been a notable rise in investor participation, with a delivery volume of 64,000 shares on September 9, which is up by 69.85% compared to the 5-day average. However, the stock's performance over the past week shows a decline of 5.12%, and it has underperformed the benchmark Sensex, which has gained 1.04% during the same period. The stock is currently trading higher than its 100-day moving average but lower than its 5-day, 20-day, 50-day, and 200-day moving averages. There are no positive or negative factors provided that could further explain the stock's recent movement.
Broader market context reveals that while Atmastco Ltd has experienced a decline of 18.15% year-to-date, the Sensex has increased by 5.62% in the same timeframe, indicating a significant underperformance relative to the broader market. In the short term, the stock's recent uptick contrasts with its overall negative trend, particularly over the past week and month, where it has seen declines of 5.12% and 1.30%, respectively. This suggests that despite today's positive movement, the stock is still facing challenges in regaining its footing compared to the benchmark index.
