A company reports the best quarter in its history. Profit up thirty per cent, revenue at a record, margins improving.
The stock fell eight per cent that morning.
Somebody watching this for the first time concludes that the market is irrational, or rigged, or both. It is neither. What happened is entirely explicable, and understanding it is the difference between reading prices as information and reading them as noise.
First, the mechanism
Before any list of factors, one thing has to be clear, because everything else follows from it.
A share price does not respond to news. It responds to orders.
The price is simply the level at which the last trade happened, and it changes when the balance of buyers and sellers in the order book changes. News matters only because it changes what people are willing to pay, which changes the orders they place.
That sounds pedantic and it is not. It explains why a price can move violently on nothing, and sit still through something important. What matters is not whether an event is significant. It is whether the event changes anyone’s willingness to transact, and by how much.
Why good results can sink a stock
Now back to the company with the record quarter.
By the time results are announced, the market already has a view. Analysts have published forecasts, the price has already moved in anticipation, and the number everyone is waiting for is not the profit. It is the difference between the profit and what was expected.
Profit up thirty per cent against an expectation of thirty-five per cent is a disappointment, whatever the headline says. Anyone who bought expecting the higher number now has a reason to reconsider, and the selling that follows is not irrational. It is a repricing against a different set of expectations.
This is the single most useful idea in this post. A share price already contains a forecast. News moves the price only to the extent it differs from that forecast.
It is also why a struggling company can rally on a bad quarter that was slightly less bad than feared, which looks absurd until you know what the price was already assuming.
The four things that actually move prices
The company itself. Results against expectations, guidance about the future, a large contract, a management change, a governance problem. This is the category most directly linked to the business you own.
The sector. A commodity price, a regulation, a tariff, a rival’s results. Companies in the same industry move together more than most people expect, because the same conditions apply to all of them.
The wider market. Interest rates, inflation, the currency, oil, a global event. When the mood turns, almost everything falls together, and the quality of your particular company offers very little protection on that day.
Flows. This one is underappreciated and often the real explanation. Prices move when large pools of money need to buy or sell for reasons that have nothing to do with the company’s merit. Foreign investors reallocating between countries. Domestic funds deploying inflows. And index changes, where a stock added to a major index is bought by every fund tracking that index, regardless of what anyone thinks of it.
A stock can rise for weeks because a large buyer is accumulating, and fall for weeks afterwards because they stopped. Nothing about the business changed.
The moves that are not moves at all
Some price drops are pure arithmetic, and panicking about them is one of the most common beginner mistakes.
Dividends. When a company pays a dividend, the money leaves the business. A share trading at ₹500 that pays ₹10 is worth about ₹490 the moment it stops carrying the right to that dividend. All else being equal, the price drops on the ex-date by roughly the dividend amount. You have not lost anything on the day. Part of the value moved from the share price into your bank account, where the dividend is taxable.
The date that decides eligibility is the ex-date, not the record date. Buy on or after the ex-date and the dividend belongs to the previous owner, however long you then hold.
Since settlement moved to one day, the two dates sit much closer together than they used to, often on the same day. Guides written for the older cycle describe a two-day gap, which no longer applies. The reliable habit is to read the exchange announcement for the specific dates rather than assuming a gap, and to buy at least one trading day before the ex-date if you want the entitlement.
Bonus shares. A one-for-one bonus doubles the number of shares and halves the price. A ₹800 stock becomes two shares at ₹400. Your holding is worth exactly what it was.
Stock splits. The same thing by a different mechanism. A five-way split turns one ₹1,000 share into five ₹200 shares.
Each of these looks alarming on a chart and none of them is a loss. If you ever open your app to find a holding down fifty per cent, check for a corporate action before checking the news.
Liquidity decides how far a price travels
The same news does very different things to different stocks.
In a large company with deep trading, a big seller can exit without moving the price much, because there is enough on the other side to absorb it. In a small company, the same seller can knock the price down several per cent on their way out.
So the size of a price move tells you about the liquidity as much as about the news. A dramatic move in a thinly traded stock may mean far less than a modest move in a heavily traded one.
What does not move the price
Your order. Almost certainly.
For most actively traded stocks, a typical retail order is small compared with the overall trading volume. This is worth internalising for two reasons. It should stop you worrying that you are giving something away by placing an order. And it should stop you assuming that a price moving right after you bought had anything to do with you.
The timeframe question
Over a single day, prices are mostly moved by mood, flows and positioning. Over a decade, they are mostly moved by what the business earned.
Both statements are true. They describe different timeframes, and most disagreements about whether markets are rational are really people standing in different ones and talking past each other.
The practical consequence is that a daily price move is usually not information about your company, and treating it as such will make you trade more and know less.
Common questions
Why did the share price fall despite good results?
Because the price already reflected an expectation, and the results were measured against that expectation rather than against last year. Good but below forecast is a disappointment to the market.
What makes share prices go up and down?
The balance of buying and selling in the order book. That balance is shifted by company news, sector conditions, wider market and macro factors, and flows of large money moving for its own reasons.
Why did my stock drop suddenly with no news?
Check for a corporate action first. Dividends, bonuses and splits all reduce the quoted price mechanically without any loss to you. If not, it may be a large seller, a sector move, or thin liquidity amplifying a modest order.
Does the share price fall after a dividend?
Yes, all else being equal, by roughly the dividend amount, on the day the share stops carrying the entitlement. The value moved from the share into the payout rather than disappearing.
What is the ex-date?
The first day a share trades without the right to a declared dividend or other corporate benefit. It is the date that decides eligibility. Since settlement moved to one day it now sits very close to the record date, often on the same day, so check the exchange announcement rather than assuming a gap.
Does a bonus issue make me richer?
Not immediately. You hold more shares at a proportionately lower price and the total value is unchanged on the day.
Do foreign investors move Indian markets?
Large flows in either direction can move prices considerably, particularly in the larger stocks they hold, and often for reasons about global allocation rather than about any Indian company.
Can my own buying move the price?
Not in any reasonably traded stock. In a very small or illiquid one, a large order can, which is a reason to use limit orders there.
The short version
A price moves when the balance of orders changes. News matters only insofar as it differs from what the price already assumed, which is why good results can send a stock down.
And before you interpret any sharp move as a verdict on your company, check whether it was a dividend, a bonus or a split, because a good share of the frightening drops people see are arithmetic rather than events.
