GF Securities says AI stock correction is nearing an end as capital rotates from memory to CPO optics
Hong Kong-based GF Securities said in its August technology sector report that the July pullback in AI-linked stocks is close to ending, with the Philadelphia Semiconductor Index seeing its forward P/E fall to 27x and crowded leveraged positions largely cleared out. The firm added AMD, Foxconn and Lumentum to its preferred list while removing United Microelectronics, MediaTek and ASML, arguing that current leadership is concentrated in GPU, CPU and optics rather than mature-node foundry, smartphone chips or front-end lithography. GF Securities also said supply-chain capital is rotating away from memory components toward optical interconnects, with near-packaged optics and co-packaged optics emerging as the next focus. It projected U.S. cloud service providers’ capital expenditure growth at 85% in 2026, 45% in 2027 and about 20% in 2028, while estimating debt issuance at $257 billion in 2026 and $419 billion in 2027. The report said net leverage should still stay around 0.5x by 2029. At the same time, it kept a cautious near-term view on smartphones and warned that NAND oversupply could begin to surface in the second half of 2027.
