Investment view

At $21.66, DOCS requires a -14% five-year revenue growth rate to justify its enterprise value — less than the business already delivers, at 13%.

The ranking statistic lives on the growth axis and the axes AGREE (+28.40pp margin-axis slack against +26.61pp growth-axis at the NTM base), so the declaration is reported rather than load-bearing.

The value rests on an exit multiple of 37.8x, a terminal operating margin of 34% and a 10.7% cost of capital. Move any one of them materially and the conclusion moves with it, which is why the required-versus-demonstrated test above carries more weight here than the point value.

The strongest argument against this view: NAMED CAUSE, not a valuation bear case.

Risk and sell discipline

Impairment case

NAMED CAUSE, not a valuation bear case. Concentrated pharmaceutical marketing budgets, contracting, mediated by agencies that can aggregate several disclosed customers into one decision. In FY2026 a SINGLE CUSTOMER crossed 10% of revenue for the first time in Doximity's history (Customer B, 11%); the >=$500k cohort is 125 customers producing 83% of revenue. The company discloses that customers buy indirectly through marketing agencies 'some of whom represent a number of customers', so THE DISCLOSED CONCENTRATION IS A FLOOR, not A LEVEL.

Estimated probability 25%, against the 22% level at which the position would be resized. It sits above that level, so this case could not be carried at full size.

Fundamental invalidation

Falsifiable and fundamental — not one of them is a price condition.

Price-based risk trigger

A daily close below $18.91 triggers an immediate review of the thesis and pauses additional buying. It is not an automatic sell unless a separate fundamental invalidation condition has been breached.

Upside sell discipline

Trim or exit on valuation and opportunity cost when the forward 12-month expected return falls below 0% net of costs. E[R] > 0 is the standard; there is NO percentage hurdle — the 4.7% cash hurdle was retired 28 July 2026 and must not be reintroduced. On approach to the $24.98 target the case is reviewed rather than added to; a target reached is a reason to re-examine the position, not to hold it by default. The position is trimmed once forward expected return falls below 0% net of costs, because the capital has a better use elsewhere in the book.

Quality, valuation and liquidity can prevent a position on their own. The remaining four inform timing, sizing and monitoring, and never reject an investment by themselves.

Bottom line

The strongest case for mispricing is that the business already delivers +26.6 percentage points more growth than the price requires. The most important unresolved uncertainty is the permanent-loss mechanism: NAMED CAUSE, not a valuation bear case. The next evidence that should change the portfolio decision is the next scheduled results, or a daily close below $18.91, which forces an immediate review.
