Buy TSM Below $400

Taiwan Semiconductor Manufacturing (NYSE:TSM | TSM Price Prediction) at $404.35 looks attractive on weakness below $400 based on the setup discussed below. The stock has already touched $386.12 on May 12 and $391.47 on May 13 before bouncing back, and the setup heading into summer suggests sub-$400 prints look like an opportunity.

TSMC fabricates the world’s most advanced logic chips, with a 72.3% share of the global foundry market and customers ranging from Apple to NVIDIA to Amazon. AI and high-performance computing now drive 61% of Q1 2026 revenue, which is why the stock has roughly doubled off its 52-week low of $186.84. What brought it back to the $400 zone is geopolitics, not earnings results.

Trump’s Beijing Trip Put Taiwan Back in the Crosshairs

The recent mid-May Trump-Xi summit in Beijing rattled investors who heard softer language on cross-strait policy. Xi reiterated that Taiwan is the core bilateral issue, and short sellers capitalized. That noise is why a stock printing $3.49 in Q1 EPS on an 8.39% beat trades at a forward multiple of 26.

The Bull Case: AI Demand Is Not Slowing Down

TSMC raised its 2026 revenue growth outlook to over 30%, locked in a role supplying chips for Amazon’s $150 billion AI data center buildout, and authorized a $20 billion capital injection into TSMC Arizona on top of $31.3 billion in advanced capacity appropriations. Profit margin sits at 46.5%, return on equity at 36.2%, and quarterly earnings growth ran 58.4% year over year. Institutions leaned in, with Bessemer adding 67.8% to its position last quarter.

The Bear Case: Concentration and Tariff Risk

Bears point out that TSMC is over 40% of Taiwan’s Taiex index, that AI revenue concentration cuts both ways, and that one Simply Wall St DCF model pegs fair value at $215.69. A more punitive U.S. tariff regime on Taiwan-fabbed silicon or an Apple shift toward Intel foundry would compress margins. Sands Capital and First Eagle have both trimmed sizable positions.

The Hold Case: Wait for a Cleaner Setup

The patient view says the geopolitical premium is real and the stock has run hard. RSI of 56.30 is neutral, not oversold, and the 50-day moving average sits at $367.59. If you missed the April washout into the $364 to $370 zone, waiting for another flush before June ex-dividend is defensible. The cost of patience is that AI orders keep compounding.

The Data Behind the Setup

The stock currently trades at $404.35, down 3.20% on the day, against an analyst target of $463.45, implying meaningful upside. Of the analysts covering TSM, 5 rate it Strong Buy, 12 Buy, 2 Hold, and zero Sell. Year to date, the stock is up 30.70%, well ahead of the S&P 500’s roughly mid-single-digit gain. Forward P/E of 26 looks reasonable against 35.1% revenue growth.

The Verdict: Why Sub-$400 Is the Window

At $404.35, Taiwan Semiconductor screens favorably on weakness below $400, based on the data below.

Polymarket traders assign a 98.35% probability that China does not invade Taiwan by June 30, 2026, and 92.55% through year end. The Trump-Xi summit produced rhetorical warnings rather than concrete war plans. TSMC fabricates the chips that power American AI, defense, and consumer technology. Letting that capacity fall under coercion is a non-starter in Washington, regardless of which party is counting votes.

The path to higher prices runs through Q2 earnings in mid-July, continued AI capex commitments from hyperscalers, and gradual de-risking as Arizona fabs ramp. What invalidates the thesis is a genuine PLA mobilization signal or an Apple-Intel foundry announcement, neither of which the market is currently pricing.

Sub-$400 looks like a window of opportunity rather than a durable floor, and windows on the world’s most important foundry tend to close quickly.
