AI Holders Summary · Q1 2026

Sarepta Therapeutics shows an unusually thin institutional footprint in this snapshot: only three reported holders account for about .9K of 13F value, led by Versant Capital Management at roughly 74% of the tracked book, MassMutual Private Wealth & Trust near 22%, and Cedar Mountain Advisors around 4%. The sharp signal is not accumulation but retreat: Versant cut its stake from 646 to 450 shares, while MassMutual added just 34 shares and Cedar Mountain held flat, leaving ownership concentrated in micro-positions rather than broad institutional sponsorship.
