Weinstein Stage Analysis Framework

Every stock spends most of its life in one of four stages — and only one of those stages is worth owning. The investor who can identify the stage reliably eliminates most of the market's losses before they occur.

Why This Matters

Stan Weinstein developed Stage Analysis to create a simple, objective framework for classifying any stock's position in its price cycle. The methodology uses the 30-week moving average as the primary indicator of institutional sponsorship and the stage boundaries, combined with volume analysis to confirm each stage transition. The principle is straightforward: buy Stage 2, avoid everything else.
