MACOM shares surge after BMO upgrades to Outperform and highlights AI optical chipset

MACOM Technology Solutions (MTSI) stock jumped 6‑7% on October 1‑2, 2026 after BMO Capital raised its rating to Outperform and set a $335 price target. The upgrade was driven by strong demand for the company's RF and microwave products and the launch of a 3.2‑terabit optical chipset for AI data centers. The rally was reinforced by the company's high margins and solid balance‑sheet metrics.

BMO Capital’s upgrade and $335 target suggest the analyst expects the AI and defense product portfolio to drive earnings growth, which could support further price appreciation for investors holding MTSI. The higher rating also may attract additional institutional buying.
