Background

Omnicom announced CEO Troy Ruhanen's retirement and Andrew Robertson's appointment as CEO of Omnicom Advertising.
Potential modest short‑term volatility; no clear directional bias.

Market effects
May signal continued focus on AI‑enabled advertising tools across the marketing sector.
Limited to U.S. and global advertising markets; no broader regional effect.
Minor, as Omnicom is a large holding company but the news is governance‑focused.
