Stage analysis: the four stages every stock goes through

The whole idea in one minute

Every stock you will ever look at is doing one of four things:

1. Resting after a fall: going sideways, going nowhere. This is Stage 1.
2. Rising: making higher highs and higher lows. This is Stage 2.
3. Stalling after a long rise: going sideways at the top. This is Stage 3.
4. Falling: making lower highs and lower lows. This is Stage 4.

Then a new base forms and the cycle starts again. Tap any stage below to see what it means. The percentages are live: how much of the US market is in each stage today.

The whole method comes down to one rule: own stocks in Stage 2, and stay away from Stage 4. The rest of this lesson is about telling which stage a stock is in, early and without guessing.

The one line that tells you the stage

You don't need ten indicators. You need one line on the chart: the 30-week average.

It is simply the average closing price of the last 30 weeks, recalculated every week. Think of it as the stock's long-term trend line. Short-term noise, such as a bad day, a rumor or a big order, barely moves it. A real change in the trend does.

Weinstein's rule is easy to remember: price above a rising line is healthy; price below a falling line is sick. If you use daily charts, the 150-day average is roughly the same line.

Here is how the line, the price and the volume behave in each stage:

Stages 1 and 3 look alike on their own: price chopping around a flat line. What tells them apart is what came before. A long fall comes before Stage 1; a long rise comes before Stage 3.

Stage 1: the quiet base

After a stock has fallen for a long time, the selling eventually runs out. The price stops dropping and starts moving sideways. The 30-week line, which was pointing down, flattens. Nothing exciting happens, and that is the point.

What to do in Stage 1: watch, don't buy. A base tells you the selling has slowed. It does not tell you that buyers have taken over. Many bases fail and roll over into another fall, as you will see with Peloton below. The time to act is when the stock leaves the base on the way up.

Stage 2: the only stage worth owning

Stage 2 begins when the price breaks out of its base, usually on a burst of volume, and the 30-week line turns up. From then on the pattern is simple: higher highs, higher lows, and every dip stays above the rising line.

You did not need to catch the exact bottom or sell the exact top. You needed to recognize the stage and stay with it while it lasted.

Why does Stage 2 work like this? Because the biggest buyers in the market, such as mutual funds, pension funds and hedge funds, cannot buy a large position in a day. They buy for weeks and months. That steady buying is what turns the 30-week line up and keeps the dips shallow. A Stage 2 chart is the footprint of that buying.

Right now, 928 US stocks are in Stage 2, or 29% of the market.

Stage 3: the top that looks like a pause

No advance lasts forever. At some point the buyers who drove Stage 2 are fully invested, and the sellers start meeting them evenly. The price stops making progress and swings back and forth. The 30-week line, which was rising, flattens out.

From the inside, Stage 3 rarely feels like a top. It feels like a pause before the next leg up, which is exactly why so many people give their gains back here. The telltale signs:

• The swings get bigger, not smaller.
• Volume stays heavy, but the price goes nowhere.
• The price starts dipping below the 30-week line, and the line stops rising.

What to do in Stage 3: protect what you have. Tighten your stop-loss or take some profit. Don't open new positions in a stock that has stopped advancing.

Stage 4: why "cheap" gets cheaper

Stage 4 starts when the price breaks below the 30-week line and the line rolls over and points down. From there, every bounce runs into sellers. Lower highs, lower lows.

This is where most individual investors lose the most money, and almost always for the same reason: the stock looks cheap compared with where it used to be.

Below a falling 30-week line, every price that looks cheap can get cheaper. Stage 4 does not end because a stock has fallen enough. It ends when the selling runs out and a real base forms, and even then, you wait for Stage 2.

The whole cycle, on one stock

Put the four stages together and you get the full life of a trend. Here is Abercrombie & Fitch again, from before its advance to well after it ended:

Every stock you hold is somewhere on this path. The question to ask is always the same: where?

Why you can trust it

Weinstein built stage analysis on American stocks in the 1980s, so it is fair to ask whether it still holds up. Two things should give you confidence.

The data is real, and it covers every kind of market. After every close we classify every US stock we cover with enough history, 3,075 of them today, into its stage. Our record of the whole market's stage mix goes back to October 2018, through the late-2018 selloff, the 2020 Covid crash, the 2021 boom, the 2022 bear market and the 2025 tariff selloff.

The method is simple enough to check with your own eyes. Every stock page on Stage2Stocks shows the stage, how long it has been there, and the chart it came from. Nothing is hidden behind a black box: if the chart doesn't agree with the stage, you will see it.

That chart also shows why the market comes first. When most of the market is in Stage 4, even good companies fall with it. When most of it is in Stage 2, the wind is at everyone's back. That is the idea behind today's market read, and it's worth checking before you look at any single stock.
