Fundamentals
Valuation and ratings
Personalis, Inc. trades at $16.28, which is 62% above the $6.23 our fair value estimate puts on the business. On that measure it screens as expensive, which is not the same as saying it will fall.
Our moat model scores it 16 out of 100, which is little in the way of a moat. A moat is a structural reason competitors cannot take the profits away, and it matters more to a long holding period than any single quarter's numbers do.

Estimates are the published analyst consensus and move often. An earnings date is scheduled, not certain, and a share tends to reprice most violently on the day itself.
