The cluster's bullish conviction is corroborated by Medpace's strong Q3 earnings and raised guidance, but 13F data is 45+ days stale — the positions may have already been adjusted. Monitor for any insider buying (Form 4) in the coming weeks to confirm continued conviction, and watch Q4 2026 earnings for guidance execution.
Executive Summary
A bullish institutional cluster formed in Medpace during Q3 2026, with 5 asset managers accumulating $44.1M in net new positions (led by Artemis Investment Management nearly tripling its stake to $59.0M) while only Wasatch Advisors trimmed $46.3M. The cluster aligns with Medpace's strong Q3 earnings reported two days ago, which featured an 8.5% revenue beat, raised full-year guidance, and a new $1.0B buyback authorization — reinforcing the thesis that institutional buyers were positioning ahead of positive fundamentals.

Financial Impact
5 institutions accumulated $44.1M in net new positions (total buyer holdings $73.3M) while 1 seller reduced by $46.3M, resulting in a net institutional inflow of approximately $44.1M
Risk Factors
- 13F data has a 45-day reporting lag; the cluster may have been partially or fully unwound since quarter-end
- Wasatch Advisors' $46.3M trim offsets a significant portion of the buying, suggesting mixed institutional sentiment
- The cluster is dominated by smaller asset managers (Artemis at $59M is the largest); no major hedge fund or activist presence to drive a catalyst
