Taiwan Semiconductor Manufactur (TSM) stock analysis, November 18, 2025: TSM tests $275 support after four down weeks ahead of Nvidia earnings

Published November 18, 2025 · TSM chart, levels and live analysis

Key Updates

TSM extended its pullback, falling another -2.45% to $275.10 since the last report on November 17. Despite solid Q3 results and a board-approved capital spending plan, the stock has been under pressure for a fourth straight week. The company's fundamentals remain strong on rising demand for AI chips, but sentiment is cautious ahead of Nvidia's earnings.

Current Trend

TSM is in a short-term correction from its November highs, down -6.77% over the past month. The six-month move is still impressive at +41.64%, underscoring the strength of the longer-term trend. The current pullback comes as investors question the durability of the AI boom ahead of Nvidia's report, putting pressure on the whole semiconductor group.

Investment Thesis

The TSM thesis rests on its dominant position in advanced chip manufacturing and growing demand for AI processors. The company remains a key beneficiary of the AI revolution, making chips for the biggest names in tech. The board's recent approval of major capital spending confirms plans to expand production capacity.

Thesis Status

The thesis is unchanged and backed by fresh data. Strong Q3 results and upbeat guidance confirm steady demand for TSM's products. The board's approval of large investments shows management confidence in the long-term outlook. The current pullback is technical in nature and does not undermine the fundamental case.

Key Drivers

The main drivers remain strong AI chip demand, highlighted in Baron Funds' report, and solid Q3 results with improved guidance, noted by RiverPark Advisors. The key near-term catalyst is Nvidia's upcoming earnings, which could set the tone for investor sentiment on the AI trade, as Reuters points out.

Technical Picture

TSM trades at $275.10, off recent highs above $300. The stock is in a corrective move within a longer-term uptrend. Support sits at $270-275; a break below that could open a test of $250. Resistance is at $290-295, and a move through that level would clear the way for new highs.
