Strategy Blog
Investors, traders, fund managers, and market pioneers whose methods shaped how markets are studied.
Each profile digs into how a great market thinker made decisions: what they watched, what they avoided, and which lessons still help a retail investor read businesses, prices, risk, and crowd behavior with more judgment.
Trader · Price-volume market structure and tape-reading discipline
Before charts became software and volume became a dashboard input, Richard D. Wyckoff turned ticker tape, market psychology, and professional accumulation into one of technical analysis's most durable trading languages.
Investor · Systematic statistical arbitrage
The mathematician behind Renaissance Technologies turned trading into a scientific search for repeatable signals, but the legend of Medallion also carries lessons about secrecy, capacity, taxes, and the limits of models.
Investor · Quantitative factor investing
James O'Shaughnessy's career sits at the hinge between old Wall Street stock picking and the modern, data-heavy world of factor investing, model portfolios, and custom indexes.
Investor · Cycle-aware credit investing
The Oaktree co-founder turned risk control, cycle awareness, and distressed-credit discipline into one of modern finance's most influential investment franchises.
Investor · Global macro reflexivity
The financier who made reflexivity a trading doctrine turned imperfect knowledge into a weapon, built one of macro investing's defining records, and left a legacy that still divides markets and politics.
Investor · Concentrated activist value
The Pershing Square founder made his name by turning research into public pressure. His later career asks a harder question: can an activist built for confrontation become a durable allocator of permanent capital?
