UBS recently released a research note stating that current market sentiment has already priced in YOFC's high-margin data communication business growth potential and initial optimism around hollow-core fiber, leaving limited upside. The report acknowledged hollow-core fiber's long-term potential, projecting that the technology will mature over the next 2-3 years and contribute meaningfully to revenue. While it serves as a strategic growth lever for the group, UBS believes its short-term impact on profitability remains limited.
