Why is Diffusion Eng falling/rising?

As of 17-Oct, Diffusion Engineers Ltd is experiencing a decline in its stock price, currently at Rs 361.60, which reflects a decrease of Rs 18.95 or 4.98%. The stock has underperformed its sector by 4.48% today and has been on a consecutive fall for the last two days, accumulating a total decline of 5.65% during this period. Additionally, the stock touched an intraday low of Rs 356.1, indicating a drop of 6.42%. In terms of returns, the stock has seen a negative performance over the past week and month, with declines of 3.34% and 7.07% respectively, although it has shown positive year-to-date and one-year returns of 8.98% and 21.22%. There is no information available regarding positive or negative factors that could further explain the recent movement.
Broader market context indicates that while the Sensex has gained 1.76% over the past week and 1.52% over the past month, Diffusion Engineers Ltd has lagged significantly behind these benchmarks. This underperformance in the short term suggests that investor sentiment may be shifting away from the stock, despite its relatively strong long-term performance. The rising investor participation, as evidenced by an increase in delivery volume, may not be sufficient to counteract the current downward trend, especially given the stock's recent price movements and its position relative to moving averages.
