Shares of TSMC's Brazilian depositary receipt (TSMC34.SA) dropped 5.6% to R$290.28 on July 1, erasing a two-day surge of roughly 5% that had been fueled by raised forecasts for NVIDIA's advanced chip packaging demand. With TSMC's Q2 earnings call set for July 16, the selloff raises a pointed question: are investors right to lock in gains, or is the pullback mispricing a company whose factories literally cannot keep up with orders?

  • NVIDIA Has Already Bought the Future — And That's TSMC's Floor

NVIDIA has reportedly booked over 50% of TSMC's projected advanced packaging capacity for 2026 , with an estimated 800,000 to 850,000 wafers reserved . Capacity is being pre-booked faster than it comes online, with an estimated 85%+ of 2026–2027 capacity already locked . That means TSMC's revenue visibility stretches years out — a rare luxury for any manufacturer — but it also means short-term stock moves are driven by sentiment, not substance.

  • The Numbers Are Staggering, and Earnings Could Relight the Fuse

TSMC posted Q1 2026 revenue of $35.9 billion, with net income up 58.3% year-over-year . Gross margin hit 66.2% — extraordinary for a hardware business. Management raised full-year 2026 guidance to over 30% revenue growth and guided Q2 at $39.0–$40.2 billion . With earnings just two weeks away, any beat could quickly reverse today's profit-taking.

  • Packaging, Not Chips, Is Now the Real Bottleneck

By mid-2026, advanced packaging utilization — not raw wafer production — has become the binding constraint on AI hardware supply . TSMC plans to boost this capacity to roughly 127,000 wafers per month by end of 2026 , nearly quadrupling from 2024 levels. This gives TSMC pricing power that insulates margins even as it spends aggressively — capex is guided toward the top of its $52–$56 billion range .

  • The Risk Everyone Whispers About: Over-Ordering

Industry watchers warn investors should look for signs of "over-ordering" that could lead to a future inventory correction . If hyperscalers like Google and Meta slow their buildouts, today's sold-out capacity could become tomorrow's oversupply. Google has already cut its 2026 chip production target by roughly 25% due to packaging constraints , a sign that not every customer can — or will — follow NVIDIA's pace.

The selloff looks mechanical — classic profit-taking after a sharp run — rather than fundamental. But with the stock up ~84% over the past year, even believers should watch July 16 closely.
