About this routine

In his landmark book The Intelligent Investor, Benjamin Graham defined the defensive investor as someone focused primarily on safety of principal and freedom from constant exertion. Unlike active traders, the defensive investor relies on clear quantitative rules to manage a conservative portfolio. A periodic Benjamin Graham defensive investor portfolio review enforces these quantitative safeguards without requiring daily market monitoring.

This review session applies Graham's classic defensive rules step by step. You start by evaluating your overall balance between stocks and high-grade bonds or cash. Next, you run your equity holdings through strict filters: size of the company, strong liquidity, uninterrupted dividend histories, stable earnings growth over a decade, and strict limits on price relative to earnings and book value.

By maintaining fixed asset bounds and clear quality filters, you protect your portfolio against speculative momentum. The final step rebalances assets back to your baseline split whenever market swings shift your target ratio.

Why this routine works

Prevents emotional trading by relying on strict quantitative criteria
Maintains clear capital protection across stocks and fixed income
Filters out overvalued or financially unstable companies systematically
