Benjamin Graham on TSMC
The record's own hedge — a $265 billion US buildout — is a company pricing a risk Graham's arithmetic has no cell for.
Graham’s tests for a common stock — adequate size, a strong financial condition, earnings that haven’t fallen over a full cycle, growth visible in the numbers rather than in the story (Security Analysis) — are exactly the tests TSMC’s most recent quarter passes without a generous reading. Q2 2026 revenue rose 36% year over year to about $39.45B; net income rose 77.4% to about $21.9B (texxr.com/1173046). Measured the way Graham measured a business, this is close to as clean a record as the framework rewards.
What the framework has no tool for sits one layer down. Graham’s margin of safety is a statistical concept, built from a spread of historical outcomes that includes bad ones — and it assumes the bad outcomes in that spread are business-cycle bad: a weak year, a demand slump, the kind of adversity a bond analyst’s “depression test” is built to survive (The Intelligent Investor). The risk the record keeps attaching to TSMC isn’t that kind. A January 2026 Wall Street Journal piece described TSMC as having provided a “Silicon Shield” for Taiwan for decades, in the same reporting cycle that logged a $265B TSMC pledge across four planned US fabs (texxr.com/1161705, texxr.com/1173081) — a hedge being built in the open, against a risk that isn’t a slow earnings decline but a discontinuity.
Graham’s statistics were built to average out variance, not to price a scenario where the underlying claim on the business is what’s in question. His answer to any risk his numbers couldn’t characterize was consistent — widen the margin rather than guess at the unknown — but a margin wide enough to cover a discontinuity like that isn’t a number his framework produces. It’s an acknowledgment of where the framework’s edge sits.
