BofA Buys TSMC, KeyBanc Flags Apple Risk, AMD Downgraded — AI Chip Analyst Moves Roundup

A wave of analyst moves across the AI semiconductor sector this week: BofA reiterates Buy on TSMC while dismissing competitive fears, KeyBanc flags stretched Apple valuation with spending data showing cracks, AMD gets a downgrade, and Samsung and SK Hynix receive price target upgrades.

BofA Reiterates Buy on TSMC, NT$2,560 PT — "Competitive Fears Overblown"

Bank of America reaffirmed its Buy rating on TSMC with a NT$2,560 price target, directly addressing market concern that Samsung's SF3 and Intel's 18A processes represent a mounting threat to TSMC's foundry leadership.

BofA's counter: Samsung SF3 and Intel 18A are running at only 20,000 to 25,000 wafers per month in aggregate — a fraction of TSMC's capacity. At that scale, competitive impact is negligible. TSMC's N2 node is progressing ahead of schedule, and major customers — Apple, Nvidia, AMD — remain deeply committed.

TSMC N2: Ahead of Schedule

TSMC's 2-nanometer (N2) process is tracking ahead of original timeline estimates. N2 delivers power efficiency and performance improvements over the current-generation N3. Apple's next A-series chip, Nvidia's next-generation GPU, and AMD's roadmap processors are all expected to be built on N2.

The ahead-of-schedule progress reinforces TSMC's leadership position. With Samsung continuing to struggle with SF3 yields, TSMC's N2 lead increases the switching cost for any customer considering a move to an alternative foundry.

KeyBanc: Apple Stretched Valuation, Spending Data Showing Cracks

KeyBanc Capital Markets assigned Apple a Sector Weight (neutral) rating, flagging what it sees as a stretched valuation. The current stock price embeds an AI-driven iPhone supercycle thesis — but KeyBanc says consumer spending data is showing cracks that call the thesis into question.

The core concern: whether Apple Intelligence and AI features will drive iPhone upgrade cycles meaningfully above prior cycles is unproven. The ASP expansion and services revenue growth required to justify Apple's premium multiple may not materialize at the assumed pace.

AMD Downgraded; Samsung and SK Hynix Get Price Target Upgrades

AMD received a downgrade in this week's round of analyst moves, reflecting concern that market share gains against Nvidia in AI accelerators are progressing more slowly than expected. AMD's MI300X has been adopted by select cloud providers, but the CUDA ecosystem moat has proven harder to breach than the bear case against Nvidia had assumed.

Samsung Electronics and SK Hynix both received price target increases. HBM demand is surging alongside AI data center investment, and both companies are well-positioned to benefit. SK Hynix in particular is the primary HBM3E supplier for Nvidia's H100, H200, and B200 GPUs — a direct earnings exposure to the AI infrastructure buildout.

Samsung SF3 vs. Intel 18A: The Real Competitive Picture

As BofA notes, both Samsung SF3 and Intel 18A are at minimal scale. Samsung's SF3 has faced persistent yield issues that have made it difficult to attract external customers. Intel 18A remains focused on internal production, with external foundry customer wins still in early stages.

For either company to pose a genuine threat to TSMC's market dominance, they would need to achieve TSMC-grade yield and production stability — a multi-year gap at minimum. The consensus view is that TSMC's structural advantage in advanced node manufacturing is unlikely to be meaningfully challenged before 2028 at the earliest.
