MONTAGE TECH's stock surged 6.22% in pre-market trading on Tuesday, driven by expectations of passive fund inflows ahead of its inclusion in the FTSE China A50 Index and positive developments in its CXL technology.

The company's upcoming inclusion in the FTSE China A50 Index, effective after the close on June 18, is expected to trigger mandatory purchases by index-tracking funds that replicate the benchmark. This structural inflow of buying pressure has fueled investor optimism as the effective date approaches.

On the fundamental side, Montage Technology confirmed that this year marks the starting point for CXL scaled deployment, with industry-wide commercialization expected by 2027. The company has launched its CXL 3.1 MXC chip and is sending samples to major clients, maintaining its technology leadership in the AI memory interconnect space. Montage Technology holds a 36.8% share of the global memory interconnect chip market.
