The market closes down 0.8 per cent. One headline blames global cues. Another blames an oil move. A third quotes an analyst on valuations. All three were written after the number was known, and any of them would have been written about a different number just as confidently.
Understanding a session is not about finding the reason. It is about establishing what actually happened, in an order that stops you from attaching a story to noise.
Here is a routine that takes about ten minutes.
Step one: was it a real move?
Before the why, establish the how much.
A 0.3 per cent index move is an ordinary day. It requires no explanation, and any explanation offered is almost certainly invented. A 2 per cent move is a real event.
Get the actual number first, from the markets view or the indices page. Anchoring on the magnitude prevents the most common error in market reading: constructing an elaborate narrative for a day that was statistically unremarkable.
Also check the market state. Is the session live, closed, or in a special window? A number seen mid-session is not a closing number, and comparing the two is a mistake people make constantly. PocketX carries market status and timestamps on its market surfaces for exactly this reason — a reading without its as-of time is not a reading.
Step two: was it broad or narrow?
This is the question that separates a market story from a stock story, and skipping it produces most bad conclusions.
An index is a weighted average. It can fall because most constituents fell, or because two heavyweights fell while everything else was flat. Those are entirely different days that produce the same index number.
Check breadth — how many names rose against how many fell — and then look at the NIFTY 500 industry heatmap. The heatmap answers the question visually and in seconds:
- Broad red across most sectors? A market-level move. Look for market-level causes.
- One sector deep red, the rest mixed? A sector event that dragged the index. The cause is in that sector, not in the market.
- The index down but most sectors up? A heavyweight moved. The market did not fall; one or two large companies did.
That third case is the one that generates the most nonsense commentary. A day where a single index heavyweight drops sharply gets reported as a market decline, and it was nothing of the sort.
Step three: identify the movers
Now find the specific names. The screener surfaces gainers, losers and volume screens, and the indices page shows constituents for a given index.
What you are looking for is whether the movers are explicable. A stock down eight per cent on heavy volume usually has a reason — results, an order, a regulatory development, an index change. A stock down eight per cent on thin volume may be nothing at all.
Pair the move with the volume, always. A large percentage move on small volume is frequently an artefact of illiquidity rather than a piece of information. That distinction is covered in the screener guide, and it applies just as much when reading a session as when building a shortlist.
Step four: only now, look for the news
News comes fourth deliberately.
If you read the news first, you will find an explanation and then interpret the day through it. Establishing the facts first — magnitude, breadth, specific movers — means you arrive at the news with a specific question rather than an open invitation to be persuaded.
Check the market news with the question you formed: why did this sector fall, or what happened to this specific company. That is a far more productive search than why did the market fall, which will return a dozen contradictory answers.
Distinguish the two kinds of story you will find. Some report an event: a company announced results, a regulator issued a circular, a large order was placed. Others offer an interpretation: an analyst thinks valuations are stretched. The first kind is information. The second is opinion, and it was often written to fill space beside a number.
Step five: ask the question directly
When the sequence still leaves a gap, the PocketX assistant is designed for exactly this: a plain-language question answered from current PocketX market data, with the instruments and sources behind the answer available to inspect.
The value is not that it produces an answer. It is that the answer carries its evidence, so you can check what it was built from rather than accepting a claim.
Two boundaries worth holding onto. The assistant is read-only — it explains and it does not place orders. And it is not individualised investment advice; it is explanation of market data. Where data is stale, unavailable or the market is closed, it should say so rather than paper over it. An answer that acknowledges a gap is more useful than one that fills it with confidence.
What not to conclude
Three habits worth dropping.
Do not assume a reason exists. Many sessions have no clean explanation. Markets move because a large number of participants transacted for uncoordinated reasons. "No clear driver" is an honest and frequently correct conclusion.
Do not extrapolate one session. Today's direction is close to useless for predicting tomorrow's. A routine for understanding what happened is not a routine for forecasting what happens next, and the two get conflated constantly.
Do not confuse a story with a cause. A plausible narrative attached to a number after the fact is not evidence. The test is whether the explanation was available before the move — and it almost never was.
The routine, condensed
- Magnitude. How big was the move, and was it a closing number?
- Breadth. Broad or narrow? Check the heatmap.
- Movers. Which names, and on what volume?
- News. Now, with a specific question.
- Ask. For what the first four did not resolve.
Ten minutes, in that order. It produces a defensible account of the session more often than an hour of reading commentary, mostly because it establishes the facts before admitting the narratives.
If something in the session is worth following, put it on a watchlist rather than acting on it today. A move you noticed at the close is a move you are already late to.
