Key Takeaways:

Southbound Stock Connect flows diverged sharply on July 13, with HKD4.7 billion entering KNOWLEDGE ATLAS (02513.HK) while HKD3.2 billion exited KB LAMINATES (01888.HK).
On the Shanghai-Hong Kong leg, KNOWLEDGE ATLAS recorded the highest net inflow at HKD2.4 billion, while KB LAMINATES saw the largest net outflow at HKD817.4 million, exchange data showed. The Shenzhen-Hong Kong leg followed a similar pattern, with KNOWLEDGE ATLAS attracting HKD2.4 billion and KB LAMINATES shedding HKD2.4 billion.
The divergent flows coincided with sharp stock price dislocations. KB LAMINATES tumbled 18.7%, KINGBOARD HLDG (00148.HK) fell 19.2%, and YOFC (06869.HK) dropped 12.6%. KNOWLEDGE ATLAS edged up 0.3%. BABA-W (09988.HK) and SMIC (00981.HK) also drew net inflows of HKD583.6 million and HKD479.5 million, respectively.
Total Southbound Trading turnover reached HKD127.23 billion, with net outflows at zero — the selling in laminates and fiber stocks was offset by buying in AI and semiconductor names. The extreme divergence points to a sector rotation among mainland investors rotating out of traditional manufacturing into AI-related plays, with KNOWLEDGE ATLAS emerging as the primary beneficiary.
Short selling data showed elevated activity in the outflow names. KB LAMINATES had HKD345.7 million in short sales, representing 4.1% of turnover, while YOFC saw HKD534.9 million shorted at an 8.8% ratio. KNOWLEDGE ATLAS short selling was minimal at HKD137.3 million, or 0.9% of turnover, suggesting the buying was driven by genuine long demand.
The scale of the rotation raises questions about whether the selloff in laminates and fiber names reflects company-specific triggers or a broader shift in mainland fund allocation. KB LAMINATES and KINGBOARD HLDG both lost about a fifth of their market value in a single session, moves typically associated with earnings disappointments or regulatory actions. Investors will watch for corporate disclosures in the coming days to confirm the trigger.
