1 The Story
The four stages of a stock
Stan Weinstein is an American technical analyst who edited the influential newsletter The Professional Tape Reader. His 1988 book Secrets for Profiting in Bull and Bear Markets laid out 'Stage Analysis,' a method for classifying a stock's life cycle into four stages using price, volume, and a long-term moving average.1
His framework, built around the 30-week moving average, gave investors a simple, repeatable way to buy stocks entering strength (Stage 2) and avoid those breaking down (Stage 4).1
2 The Big Idea
Buy stage 2, avoid stage 4
Every stock cycles through four stages — trade the one where strength is building.
Weinstein turned the accumulation-markup-distribution-markdown cycle into a clear, visual model: a basing Stage 1, a rising Stage 2, a topping Stage 3, and a declining Stage 4. Buy as a stock breaks into Stage 2 above a rising 30-week average; avoid Stage 4.1
3 The Method
Stage analysis
Stage 1 — basing
After a decline, the stock moves sideways near a flattening 30-week MA. Accumulation, but no trend yet — wait.
Stage 2 — markup (buy)
Price breaks up through the rising 30-week MA on volume. This is the buy zone — strength confirmed.
Stages 3 & 4 — top & decline
Sideways topping (Stage 3), then a break below a falling MA (Stage 4). Avoid or exit.
4 Try It Today
Test the idea for yourself
A no-risk exercise
Pull up a stock with a 30-week (≈150-day) moving average. Try to label where it was basing (Stage 1), trending up above a rising MA (Stage 2), topping (Stage 3), and declining (Stage 4). Notice how the simple stage label would have kept you in strength and out of weakness.
