The trimming by three asset managers, particularly the large reduction by Sumitomo Mitsui Trust Group, suggests cautious positioning despite the stock's Q3 appreciation. Monitor upcoming 13F filings for continuation of this trend and any insider selling that may corroborate institutional caution.
Executive Summary
Three institutional asset managers trimmed their CareDx positions in Q3 2026, with Sumitomo Mitsui Trust Group reducing by 47.4% (564.6K shares) and Nisa Investment Advisors cutting 57.0%. The aggregate net selling value was $7.2M, though two of the three trims saw position values increase due to the stock's appreciation during the quarter.
