Billionaire Ken Griffin Just Loaded Up on AbbVie and Abbott. Here's Whether Investors Should Follow His Lead.

Billionaire hedge fund manager Ken Griffin recently increased his stakes in AbbVie and Abbott Laboratories through his fund Citadel. The article analyzes whether retail investors should follow his lead, highlighting AbbVie's transition from Humira to new immunology drugs like Skyrizi and Rinvoq with expansion into oncology, and Abbott's strong positions in diabetes care, diagnostics, and medical devices. The author suggests both stocks merit consideration as part of a long-term healthcare allocation based on their business fundamentals rather than simply following Griffin's moves.
