Markets have corrected since July but institutions remain broadly optimistic. Wang Zijian, fund manager in Penghua Fund’s Equity Investment Division 3, said AI has faced recurring doubts since early 2023 — technology immaturity and pulse-like capex — and since early 2026 additional challenges including technical-route shifts, Fed rate hikes, cash‑flow stress, signs of commercialization peaking, excess compute supply and crowded sector positioning. Yet over the past three years leading optical‑module names have rallied roughly 100x, evidence he says that the market has underestimated AI’s transformative potential and growth runway. He added that investment depends on cycle stage: AI remains in an early development phase, market conditions do not show bubble characteristics, and therefore each deep correction could present a high‑quality accumulation opportunity.
