Structural Probability: The Second Principle of Investing

By Ruixue Lei

What if profit does not come from prediction-but from structure?

Most investment theories are built on forecasting, valuation, and narrative interpretation. Yet real markets behave as constraint-driven complex systems where prices emerge from interaction, probability, and time rather than certainty.

Structural Probability proposes a new foundation for investing. Instead of asking whether prices will rise, it asks a deeper question:
Under what structural conditions are buyers more likely to appear?

Bridging complex systems science, quantitative thinking, and financial markets, this book develops a unified framework explaining: - How prices are structurally formed rather than predicted - Why alpha emerges, decays, and compounds through time - How institutional constraints create persistent probabilistic edges - Why long-term returns are the outcome of survival and compounding, not correctness

This is not a trading manual or a promise of quick profit. It is a theoretical map for navigating uncertainty-intended for serious investors, researchers, and thinkers seeking a deeper logic beneath market behavior.

A foundational work on probability, structure, and time in investing.
