TSMC stock heads into Thursday’s third-quarter earnings with much of the good news already visible, leaving investors focused on whether margins and guidance can justify the chipmaker’s elevated AI expectations.
The US-listed shares closed Tuesday near $445, roughly 9% below their early-October high, even after Taiwan Semiconductor Manufacturing Co disclosed record quarterly revenue.
That pullback has created a more balanced setup before the results, but the options market still expects a meaningful reaction.
Options market points to an $18 post-earnings move
Options expiring on October 16 imply a move of roughly 4% for TSMC stock after the results.
The near-the-money $445 call and put were worth about $18 combined at Tuesday’s close, pointing to an approximate post-earnings range of $427 to $463.
At TSMC’s roughly $2.1 trillion market value, a 4% move would translate into more than $80 billion of equity value changing hands in either direction.
Positioning is also concentrated around nearby strikes. Open interest in the $450 calls stood above 9,500 contracts, while the $440 puts carried more than 6,000 contracts, making those levels useful markers for the immediate reaction.
The setup matters because TSMC’s revenue surprise is already known.
The company reported third-quarter sales of NT$1.49 trillion, or about $46.7 billion, up 50% from a year earlier and above its own guidance of $44.6 billion to $45.8 billion.
Margins and Q4 guidance become the real earnings test
The market will therefore focus on profitability. TSMC previously guided for a third-quarter gross margin of 65% to 67% and an operating margin of 56% to 58%, compared with 67.7% and 60.3% in the second quarter.
An LSEG SmartEstimate expects net profit to rise 65% to NT$746.3 billion, which would mark a sixth consecutive quarterly earnings record.
Bank of America analyst Haas Liu expects gross margin near 67% and sees fourth-quarter sales rising 10% to 15% sequentially, according to TipRanks.
Liu also raised his ADR price target to $620 from $590 and described TSMC’s valuation at around 16 times estimated 2027 earnings as “undemanding”.
The fourth-quarter outlook could carry more weight than the headline profit figure. Morgan Stanley analyst Charlie Chan expects TSMC to raise its 2026 revenue growth forecast to the low-to-mid 40% range from its current guidance of more than 40%.
AI capacity and capex will decide whether the premium holds
The bigger debate is shifting toward how long TSMC can sustain extraordinary AI-driven growth while absorbing the cost of new technology and overseas expansion.
The company raised its 2026 capital expenditure forecast in July to $60 billion to $64 billion. BofA’s Liu expects spending of about $63 billion this year and as much as $83 billion in 2027 as TSMC expands 3nm, 2nm, A16 and advanced packaging capacity.
Investors will watch closely for commentary on Nvidia and custom AI accelerator demand, CoWoS packaging capacity and the 2nm ramp, where higher costs could pressure margins before utilisation improves.
Geographic expansion will also remain in focus, as TSMC has committed $265 billion to its Arizona manufacturing build-out and has been evaluating potential expansion in Texas.
Morningstar analyst Phelix Lee told Reuters that Texas was “a good location for a 2030s or 2040s expansion grand plan”, but saw little urgency while Arizona capacity is still being built.
