TSMC's AI-Driven Growth and US Expansion Face Margin and Spending Pressures

  • AI demand fuels record sales and strong guidance TSMC's May revenue jumped 30.1% year-over-year, and the company guided Q2 revenue to $39-40.2 billion with gross margins of 65.5%-67.5%. This shows the AI boom is driving real sales and profits, which supports a higher stock price.

    This point directly shows strong financial performance and demand, which is the main reason the stock should rise.

  • ASML raises forecast, confirming TSMC's capacity expansion ASML, a key supplier of chipmaking equipment, raised its 2026 sales forecast to €43-45 billion, citing AI-driven demand and TSMC's 68% June sales jump. This confirms that TSMC is expanding capacity to meet strong orders, a positive sign for future growth.

    It provides independent evidence that TSMC's business is booming and that it is investing to meet demand.

  • TSMC commits another $100 billion to US plants TSMC will invest an additional $100 billion in US fabs, bringing its Arizona total to $265 billion. This signals confidence in long-term AI demand but also means higher spending and potential margin pressure from overseas operations, which could weigh on near-term profits.

    It is a major capital commitment that affects both future growth and current profitability, making it a key driver.

  • Higher capital spending and margin dilution spook investors TSMC forecast higher capital spending despite beating Q2 estimates, and flagged 2-3% margin dilution from its 2nm ramp and 2-4% from overseas fabs. This caused a 4.4% pre-market drop in TSMC shares, as investors worry about profitability.

    It explains the immediate negative price reaction and highlights a real counterweight to the positive demand story.

Yandong Micro: insider buying vs. widening first-half loss

  • Controlling shareholder's ally to buy 150–300 million yuan of stock A party acting with the controlling shareholder plans to buy 150–300 million yuan of shares over 12 months, and on August 4 made a first purchase of 170,000 shares (8.59 million yuan). Insider buying signals the owners see long-term value, which supports the share price.

    This is the main positive force behind the stock this period.

  • First-half loss widened to 435 million yuan The 2026 interim report showed revenue up 48.5% to 979 million yuan, but the net loss widened to 435 million yuan from a profit last year, with operating cash flow negative 224 million yuan. A bigger loss and cash burn weigh on the stock.

    This is the main negative force and the key counterweight to the insider buying.

  • Revenue growth and 12-inch/silicon photonics progress, but weak margins Revenue rose for a second straight year and the company says its 12-inch chip line and silicon photonics business are advancing. But gross margin was only 6.54%, so the growth is not yet translating into profit — a mixed signal for the stock.

    It explains the business progress that could eventually justify the valuation, while showing why profits lag.
