TSMC Shares Tumble 6% as AI Euphoria Clashes With Rate Fears and Broadcom's Lukewarm Reception

TSMC fell 6% Friday despite record AI demand and Nvidia's $150B pledge, as Broadcom's disappointing report and strong labor data triggered a tech sell-off.

The world's largest chip foundry finds itself in a rare moment of contradiction: record-breaking AI demand and a massive vote of confidence from Nvidia, yet its stock suffered its steepest one-day drop in years. Taiwan Semiconductor Manufacturing Co. lost 6.01% on Friday to close at €360.00, wiping out gains made earlier in the week as a perfect storm of macro and sector-specific headwinds swept through the semiconductor complex.

Two unrelated catalysts conspired to pull TSMC lower. The first was Broadcom’s quarterly report, which, despite showing a 143% surge in AI chip revenue, fell short of the market’s already sky-high expectations. That disappointment rippled immediately across the Philadelphia Semiconductor Index, which posted its worst day since March 2020 with a 10.3% rout. The second came from the US labor market: 172,000 new jobs in May, well above forecasts, reignited fears that the Federal Reserve will keep interest rates higher for longer, a particularly uncomfortable prospect for richly valued technology stocks.

Yet beneath the surface of Friday’s sell-off, the structural story for TSMC has rarely looked stronger. Nvidia CEO Jensen Huang used the Computex forum in Taipei to announce that his company plans to invest $150 billion annually in Taiwan — a tenfold leap from the previous $10–15 billion range. The rationale is straightforward: TSMC fabricates roughly 90% of the world’s most advanced AI chips, making it the undisputed bottleneck for the artificial intelligence revolution. Analysts have begun referring to the phenomenon as the "Silicon Shield" — Taiwan’s manufacturing importance growing so critical that any supply disruption would threaten the entire global tech ecosystem.

TSMC’s own leadership acknowledges the supply squeeze will persist for years. CEO C.C. Wei has flagged that high-end chip supply will likely not catch up with AI demand until at least 2027. Internally, the company expects an oversupply gap of 25–30% through the rest of 2026, even at full utilization. The $165 billion expansion program underway in Arizona will help in the long term, but new fabrication plants take years to come online, and the industry simply cannot wait that long.

The company’s technological roadmap reinforces its dominance. The forthcoming 2-nanometer process — a key focus of the deepened Nvidia partnership — is being designed to integrate AI directly into manufacturing, boosting wafer yields and capacity planning. TSMC currently commands a 70.4% share of the global foundry market, miles ahead of Samsung’s 7.1%. Net profit has more than tripled over three years, a 206% surge driven by the 7nm, 3nm, and upcoming 2nm nodes.

Technically, Friday’s retreat brought the stock 7.57% below its 52-week high of €389.50, set just two days earlier. The relative strength index cooled from overbought territory to 54.1, suggesting the correction was more a pause than a reversal of the broader trend. The 50-day moving average of €327.34 remains comfortably below the current price, and the year-to-date gain still sits at a robust 31.87%. The 200-day moving average is 32.57% lower, underscoring the magnitude of the long-term advance.

For now, the market is caught between two forces: a fundamental AI infrastructure boom that keeps TSMC’s order books full and a short-term environment where macro data, bond yields, and inflated expectations can trigger sharp corrections. The next critical test will be the ramp-up of the 2nm process. If TSMC can steadily improve yields while translating AI demand into real capacity and margins, the dip may prove to be exactly what the strategists called it — a breather, not a breakdown.
