Jay’s Letter

jaymartin.substack.com· irregular· Published 16 days ago

Jay Martin's newsletter applies investor thinking to the mind, but the sample mostly covers macroeconomics and AI markets, such as AI company IPO risk disclosures, Iran's use of a mock Taylor Rule equation, and the 2006 mortgage market. It gives readers clear, explanatory breakdowns of financial mechanisms with a personal, argumentative voice.
