Michael Hartnett

Michael Hartnett is the Chief Investment Strategist at Bank of America Securities, where he produces one of the most influential weekly research documents in institutional finance: the 'Flow Show' report. The Flow Show provides a comprehensive weekly analysis of global fund flows — tracking where institutional investors are putting money and taking money out across equities, bonds, commodities, and money market funds globally — combined with readings of market sentiment indicators and Hartnett's own macro market outlook. The report is read by thousands of institutional investors, portfolio managers, and market strategists globally, making Hartnett one of the most widely followed market commentators in finance. His macro commentary has been notable for prescient observations about the 'bullwhip' effects in supply chains and inflation dynamics post-COVID, and for developing accessible frameworks like 'pain trades' and 'peak everything' to describe macro inflection points. Bank of America's institutional coverage of global fund flows is considered the most comprehensive and systematic of any investment bank.
