Fundamentals
Valuation and ratings
iRhythm Holdings, Inc. trades at USD115.35, which is 61% above the USD45.30 our discounted cash flow model 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 41 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.
