Aswath Damodaran, a finance professor, writes long data-driven posts on markets, interest rates, corporate earnings and valuation. Readers get charts, historical context and reasoned analysis of current market events and business questions such as venture capital incentives.
Analysis of the AI investment cycle, covering metrics such as revenue coverage of AI capital costs, data center power constraints, and company earnings signals. It also includes weekly research picks on AI and economics from the Exponential View research desk.
Long-form equity research memos on small and mid-cap space, semiconductor, hardware and defense technology stocks, built from primary filings, federal award records and orbital data. Each piece includes valuation context, bull and bear cases, and dated tripwires to watch.
Groundbreaker is a finance newsletter that argues today's AI boom mirrors the 2006-2008 subprime mortgage crisis, using analysis of reset schedules, price dynamics, and earnings quality. Readers get a contrarian, historically grounded framework for judging whether apparently cheap, growing AI-sector valuations hide the same kind of borrowed or unsustainable earnings.
