The Lean Investor is not an app, a software product, or a financial service.
It is an investing methodology designed to protect individual investors from making costly mistakes on the stock market by enforcing a set of strict rules.
On the surface, the methodology appears deceptively simple. However, underneath its minimalist design lies a strict logic that automatically prevents all classic retail investor mistakes - from high investment bank fees and sector chasing to market timing and emotional panic selling.
The methodology eliminates all financial options and choice overload by enforcing 3 unbreakable rules:
You capture maximum global market capitalization via exactly one all-encompassing index fund (ETF).
There are no options for sector funds, individual stocks, or bonds. This ensures complete geographic and sector diversification.
Your investing pipeline runs entirely on automated, recurring orders through a self-directed broker.
If you have to log in manually to click a 'buy' button, your process is broken. The system must run on autopilot to completely remove human emotion and market timing.
You treat your broker app strictly as a passive data dashboard to monitor your wealth.
You are allowed to look, but you maintain a strict Read-Only policy. Manually tweaking, buying, or selling outside the automated code is completely forbidden.
