The forest before the trees
In the first two lessons you learned to read one stock: its stage, and the 30-week line that tells you which way it is really going. This lesson steps back.
Most stocks move with the market. When the market is rising, even average stocks drift up; when it is falling, even great ones get dragged down. Stan Weinstein put it simply: look at the forest before the trees. Check the market first, then the sector, then the stock.
That raises a question that sounds easy: how is the market doing? Most people answer by looking at the Nifty. This lesson is about why that answer is often wrong.
The index can hide the market
The Nifty 50 is an average of 50 large companies, weighted by size. A few giants carry a big share of it, so when they rise the index rises — even if most of the market is falling.
More than 2,000 stocks trade on the NSE. Market breadth asks the question the index can't answer: how many of them are actually rising?
We measure it in two simple ways, both updated after every close:
- The share of stocks in Stage 2 — rising, above a rising line. Today: 30%.
- The share of stocks above their 200-day average — a rougher, faster read of the same thing. Today: 36%.
2018: a record the market didn't join
Here is the clearest example in recent NSE history. Watch both panels at the marked week.
If you only watched the Nifty in 2018, you saw a good year. If you owned small and mid-sized stocks — which is what most investors own — 2018 was a painful bear market. The index was held up by a handful of large companies while the rest of the market fell.
Breadth would have told you. All year, far fewer stocks were rising than the index suggested. That is not a signal to predict a crash. It is a reason to be careful: to buy less, to be pickier, and to protect what you already own.
2024: the warning came first
The same thing happened again, more recently.
Look at the order of events. Breadth peaked first, in February. The index kept climbing for another seven months — on fewer and fewer stocks. By the time the Nifty turned down, the market underneath had been weakening for most of a year.
The same pattern played out in 2021–22: the share of stocks in Stage 2 peaked in early 2021, the Nifty kept making records until October, and by mid-2022 fewer than 1 in 10 stocks were rising.
2020: breadth turns up from the bottom
Breadth works in the other direction too, and this is the part that makes money.
When breadth is washed out, almost everything has already been sold. When it starts to turn up — more stocks entering Stage 2 each week than leaving it — the tide is coming back in. That is when new Stage 2 breakouts have the market behind them.
How to read breadth in a minute
You don't need a formula. Ask three questions, in this order:
- Which way is it moving? Breadth improving over the last few weeks is a better sign than a high number that is slipping. Direction first, level second.
- Does it agree with the index? Index up and breadth up: a healthy market. Index up but breadth down: a narrow market, carried by a few names — be careful.
- Are more stocks starting Stage 2 than ending it? That is the market's trend, one stock at a time.
Then let the answer change how you act, not whether you think:
| The market underneath is… | What it usually means for you |
|---|---|
| Broad and improving | The wind is behind you. Good Stage 2 setups have their best odds. |
| Mixed, or narrowing | Be pickier. Fewer, better positions; tighter stops. |
| Weak and falling | Protect what you own. New buys mostly fight the tide. |
Your step for this lesson
Before you open a single stock tomorrow, spend one minute on the market.
- Is the share of stocks in Stage 2 rising or falling over the last few weeks?
- Is it agreeing with the Nifty, or disagreeing?
- What does today's market read say?
- Adjust: buy freely, be picky, or protect — before you pick a stock.

Questions people ask
What is market breadth?
Market breadth measures how many stocks are taking part in a move. If the index is rising and most stocks are rising with it, breadth is strong. If the index is rising but most stocks are falling, breadth is weak — the rise is resting on a few big names.
Why isn't the Nifty enough to judge the market?
The Nifty holds 50 large companies, weighted by size, so a handful of giants can carry it. More than 2,000 stocks trade on the NSE. In August 2018 the Nifty closed at a record while only about one NSE stock in eight was in Stage 2.
How do you measure market breadth?
Simple ways are the share of stocks above their 200-day average, the share in Stage 2, the advance/decline line (a running total of rising minus falling stocks), and new 52-week highs minus new lows. They usually agree; when they don't, the direction they are moving in matters most.
What is a good level of market breadth?
There is no magic number. The direction matters more than the level: breadth improving from a low base is healthier than breadth slipping from a high one. Watch whether it is confirming the index or disagreeing with it.
How often should I check market breadth?
Once after the close is plenty — breadth moves over weeks, not minutes. Stage2Stocks updates today's market read after every NSE close.
