I’m a walkin hedge fund
Mack compares himself with a hedge fund just to show how rich he is. Wiki definition of hedge fund:
“A hedge fund is a collective investment scheme, often structured as a limited partnership, that invests private capital speculatively to maximize capital appreciation."
You can think of hedge funds as mutual funds for the super rich. JUST AS MACK MAINE.
