Cencora (COR) was Smart Insider's stock pick of the week after Chair Mark Durcan bought $1 million in company shares on May 28.
Durcan, who has served as chair since October 2025 and has been a director since 2015, acquired 4,000 shares at $266 apiece, Smart Insider said in a Tuesday note.
The purchase followed a decline in the stock after the company's Q2 earnings report, according to Smart Insider.
Cencora also announced plans to resume share repurchases, authorizing up to $2 billion after pausing the program in January, according to the note.
The transaction was Durcan's fourth purchase during his time on the board, with previous acquisitions ranging from about $100,000 to $200,000.
Smart Insider described the purchase as "unusually large" for Durcan, adding that he did not buy shares while serving on the boards of other companies, including ASML (ASML) and Advanced Micro Devices (AMD), or during his tenure as chief executive of Micron Technology (MU).
Smart Insider ranked Cencora +1, indicating a strong positive signal.
