Why is Aimtron falling/rising?

As of 26-Jun, Aimtron Electronics Ltd is experiencing a decline in its stock price, currently at 640.55, which represents a decrease of 23.7 points or 3.57%. Despite this drop, the stock has shown strong performance over the past week, month, and year, with returns of 9.99%, 12.59%, and 29.18% respectively. However, today's performance indicates that it has underperformed its sector by 3.65%. Additionally, the stock is trading above its moving averages for 5, 20, 50, 100, and 200 days, suggesting a generally positive trend. Nonetheless, there has been a notable decline in investor participation, with delivery volume falling by 17.09% compared to the 5-day average, which may contribute to the current price drop. There are no positive or negative factors available to further clarify the reasons behind this movement.
In the broader market context, Aimtron's recent performance has outpaced the benchmark Sensex over the same periods, with a year-to-date return of 14.38% compared to the Sensex's 8.05%. This indicates that while the stock is currently facing a decline, it has been performing well relative to the market overall. The recent underperformance today, however, suggests a potential shift in sentiment among investors, which could be influenced by the decrease in trading volume. This context highlights that while Aimtron has had strong returns historically, current market dynamics may be affecting its short-term price movement.
