The Shenzhen-based storage module maker's pre-listing shares opened flat at HK$236 on PhillipMart and last printed at HK$236.6 on Futu, up 0.3 percent from the offer price, ahead of its September 8 Hong Kong debut.

Pre-listing demand for Longsys (09976.HK) proved steady, with the storage module maker's shares trading within 0.3 percent of the HK$236 offer price across two gray market platforms ahead of its September 8 Main Board debut.
PhillipMart data showed the stock opening flat at HK$236 on volume of 169,000 shares and turnover of HK$39.3 million. Futu data recorded the gray market opening down 3.4 percent at HK$228 before recovering to a last print of HK$236.6, up 0.3 percent from the listing price, on volume of 126,100 shares and turnover of HK$29.49 million.
The two data providers' figures reflect the fragmented nature of Hong Kong's gray market, where pre-listing shares trade across multiple platforms with no consolidated tape. Hong Kong stock quotes are delayed by at least 15 minutes.
The gray market's stability near the offer price suggests balanced demand ahead of the Main Board listing, with neither aggressive bidding nor heavy discounting in the pre-debut session. Longsys, a Shenzhen-based storage and memory module maker, is set to begin formal trading on September 8, when the gray market's implied valuation will face its first test against public market pricing.
Investors will watch the opening auction on September 8 for signs of whether the flat gray market performance translates into a steady debut or gives way to volatility as retail and institutional orders cross for the first time.
