The methodology at a glance
Weinstein's core observation was that every stock cycles through four stages that reflect the underlying dynamics of accumulation, markup, distribution, and markdown. The 30-week moving average (equivalent to the 150-day MA on daily charts) is the practical dividing line between stages. The principle is simple: only own stocks in Stage 2.
The Four Stages
- Stage 1 — Basing: Stock has stopped declining, trading sideways. 30-week MA flat. Smart money accumulating quietly.
- Stage 2 — Advancing: Breakout above base and 30-week MA on expanding volume. MA turns up. This is the only stage to own stocks.
- Stage 3 — Topping: Advance slows. MA flattens. Heavy volume on down weeks. Smart money distributing to latecomers.
- Stage 4 — Declining: Stock breaks below MA. MA turns down. Each rally fails. Never hold here.
Who is Stan Weinstein
Stan Weinstein edited The Professional Tape Reader newsletter from the 1970s through the early 2000s. He published his methodology in 1988, and it became foundational for position traders worldwide. Unlike many market authors, Weinstein didn't promise a magic formula — he offered a framework for understanding where any stock sits in its life cycle at any given moment.
His four-stage framework became the common language that traders like Mark Minervini, David Ryan, and countless others built their own methodologies upon. When Minervini talks about buying stocks in an uptrend, he's talking about Weinstein's Stage 2. The concept is that foundational.
Key principle: Weinstein's genius was in simplification. One moving average. Volume. That's the entire system. The 30-week MA is the tide. Price is the wave. Trade with the tide, not against it.
How Kasauti implements it
Kasauti classifies every NSE stock into one of the four stages automatically, using a daily-chart adaptation of Weinstein's framework. The Weinstein / Stage 2 button filters the entire universe to show only stocks currently in Stage 2. Each stock card displays a stage badge (S1, S2, S3, or S4) so you can see at a glance where any stock sits in its cycle — even before applying the filter.
Kasauti Insight · Nuances for Indian markets
The 2024 correction in Indian smallcaps and midcaps, driven by valuation concerns and FII selling, was a textbook demonstration of why Weinstein's framework matters for Indian traders. Stocks that had been in powerful Stage 2 advances for much of 2023 transitioned through Stage 3 (topping) and into Stage 4 (declining) over the course of several months. Traders who recognised the transition — flattening 50 DMA, heavy volume on down days, repeated failures to make new highs — preserved capital. Traders who held through Stage 3 hoping for a recovery watched significant gains evaporate.
The lesson is structural: Indian retail traders face a specific psychological trap where a correcting midcap or smallcap 'still looks good' because it's above its entry price, even as Weinstein's framework signals Stage 3 distribution. Stage analysis forces an objective decision based on what the moving averages are doing, removing the emotional attachment to paper profits.
