Perimeter Desk
Perimeter Listening / Investing
Bloomberg’s interview series explores how experienced investors and business leaders learned their craft. Barry Ritholtz asks about formative jobs, mistakes, mentors, research, and the methods guests use to make decisions. Conversations often connect a personal career story to broader questions about markets or company leadership. The same feed includes shorter At the Money discussions, which provide another entry point into specific investing and money-management topics.

The Desk’s listening note
Pick a guest’s field first; the career history often explains the investment framework better than the headline does.
Who it’s for
Listeners who want to understand how accomplished practitioners think, including advisers, finance students, and investors building a broader library of investing approaches.
A useful place to start
Start with a full interview featuring an investor or executive you recognize, then try an At the Money episode about portfolio construction or investor behavior.
