News Summary
PositiveNatera delivered a blowout Q2 2026 with 37.7% revenue growth to $752.8M (14% above consensus), raised full-year guidance to $2.85-2.91B, and achieved multiple regulatory wins for Signatera including FDA companion-diagnostic approval in bladder cancer and expanded Medicare coverage for Prospera. The strong execution and clinical momentum have driven a wave of analyst price target increases (Guggenheim to $475, Citi to $365), though routine insider selling by executives appears plan-driven rather than distress-signaling.

Shares Held and Position Value reflect total quarter-end holdings. ∆ Shares is the change from the prior quarter. % of Fund is the position's share of the fund's reported equity portfolio — it drives the size weighting in the conviction score.
Portfolio Context
Where NTRA ranks in each buying fund's book, and the positions immediately around it. What a holding sits next to often says more about the thesis than the position size does.
