For margin subscription financing, the top choice is MOMENTA-W (06880), which has the highest ceiling in its sector, the strongest cornerstone investor lineup, and a significant narrowing of losses. Yikong Zhijia (07687) is the second choice, having already achieved commercialization.

The substantial discount of Sanhuan Group (06951) and Jinghe Integration (02249) relative to their A-shares provides a safety cushion, but their overall market characteristics limit upside potential. The entry fee for Luoshi Robot (03752) is only HKD 3,838. The robotics sector has potential and is suitable for small cash participation.

Although Basic Semiconductor (09971) is the hottest with 553 times oversubscription, having zero cornerstone investors is a fatal flaw—there is no lock-up for the international placement, posing a huge risk of selling pressure on the first day of listing.
