The stock of Diffusion Engineers is expected to list at a premium of 10-15% on October 4, despite the recent sharp decline in the benchmark indices. This is due to the strong subscription numbers for its IPO and its healthy financial performance.

The IPO was subscribed 114.5 times, with strong interest from all categories of investors. This suggests that there is strong demand for the stock, which is likely to support its listing price.

The recent decline in the benchmark indices is due to a number of factors, including valuation concerns, Middle East tensions, and the fear of money flowing from India to China. However, the strong fundamentals of Diffusion Engineers are expected to outweigh these concerns and lead to a strong listing.
