AABVX — Abivax ADR · catalysts, narrative & risks

Important note on asset identity (ticker mismatch)

Before the findings, a critical caveat: your prior knowledge describes the security under ticker AABVX as a "fund of funds" that invests in other mutual funds and ETFs advised by American Century — a diversified fund vehicle, not a single equity. However, every detailed source provided describes Abivax S.A., a clinical-stage biotechnology company that trades under the ticker ABVX on both Euronext Paris and Nasdaq [1][2][5][8]. Abivax's U.S. ADR is reported as ABVX, not AABVX.
