Suzhou Dongshan Precision Manufacturing, a Chinese printed circuit board maker, raised approximately $1.84 billion in its Hong Kong initial public offering (IPO), falling short of market expectations of $2 billion to $3 billion. Analysts pointed to investor concerns over potential U.S. trade restrictions on the company's optical module business, as well as the Hong Kong market's cautious approach to large listings, as factors impacting the fundraising performance. The company began accepting investor orders on Tuesday and is expected to list in Hong Kong on October 28.
