AI Holders Summary · Q1 2026

Institutional money in Inovio Pharmaceuticals (INO) went completely still in Q2 2026: across a base of just 9 holders worth $28,230 in total, not one established position changed by a single share. The two largest holders, Mayflower Financial Advisors ($13,815, 48.9% of total institutional value) and Signature Estate & Investment Advisors ($12,131, 43.0%), together account for 92% of all institutional ownership, and both held their share counts exactly unchanged this quarter — 12,559 and 11,028 shares respectively. Every established holder in the data shows the identical pattern: zero share activity, but a meaningful decline in dollar value, implying the stock itself fell roughly a third over the quarter while institutions holding it made no move at all. The only activity in the entire dataset is two brand-new, vanishingly small positions — Decker Retirement Planning ($185) and Allied Private Wealth ($39) — neither large enough to represent a real institutional decision.

Static positions, falling value

Mayflower Financial Advisors ($13,815, 48.9% of total institutional value) and Signature Estate & Investment Advisors ($12,131, 43.0%) are the two largest holders, together representing 92% of all institutional ownership in the stock. Both held exactly the same share count as the prior quarter — 12,559 and 11,028 shares respectively — yet both positions' dollar values declined meaningfully, implying the stock's price fell by roughly a third over the period. Activest Wealth Management ($1,650, 5.8%) and MJT & Associates Financial Advisory Group ($358, 1.3%) show the identical pattern: unchanged share counts, declining dollar value.
