CYCN does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

View Full Filing (SEC EDGAR)Cyclerion Therapeutics held its shareholder meeting on August 26, 2026, to vote on proposals tied to its planned merger with Korsana. Shareholders approved five of six proposals, including the issuance of new shares to Korsana stockholders, increasing authorized shares from 400 million to 700 million, a reverse stock split (ratio between 1-for-2 and 1-for-10), the election of six directors, and the ratification of Ernst & Young as auditor. However, Proposal 4 — redomesticating the company from Massachusetts to the Cayman Islands — failed to pass, with approximately 2.1 million shares voting for and 1.3 million against.
