Plain answer
Market price is the amount at which a buyer and seller can trade an asset now; value is an estimate of what the asset is worth based on its cash flows, assets, rights, usefulness or future prospects. They can differ because prices react to supply, demand, expectations, urgency and emotion, while any estimate of value depends on uncertain assumptions.
A supermarket puts a price on a tin of beans. A stock exchange does something different.
The supermarket normally chooses the price and waits for customers. In a financial market, many buyers and sellers continually submit prices. A trade happens when compatible orders meet.
The latest trade becomes the displayed market price. It is evidence of where somebody was willing to buy and somebody else was willing to sell. It is not a certificate stating what the asset is truly worth.
This distinction explains why apparently good news can make a share fall, why two informed investors can reach different conclusions, and why a cheap-looking price can still be expensive.
Price is observable; value is estimated
For a frequently traded share, market price is easy to observe. It may change many times in a second.
Value is harder. An investor might estimate a company’s value by examining its assets, debts, profits, cash generation, competitive position and future growth. Another might compare it with similar companies. A third might estimate the future cash that could be paid to shareholders and reduce those amounts to a present value.
Each method needs assumptions.
How quickly will sales grow? What profit margin can the business sustain? How much investment will it need? What might go wrong? What return should compensate for the risk?
Small changes to those assumptions can produce a large change in estimated value. Two careful analysts can study the same evidence and reach different answers without either being dishonest.
This is why intrinsic value is better understood as a reasoned range than a hidden number waiting to be discovered.
What sets the market price?
Market price emerges from the orders that are available now.
Imagine the best buyer will pay ninety-nine pence and the best seller will accept one pound and one pence. The gap is the bid-offer spread. If a new buyer urgently agrees to pay the offer, a trade may occur at one pound and one pence.
Now imagine a large holder needs cash immediately and sells into the available bids. If there are few buyers, the order may consume the ninety-nine-pence bid and then reach lower prices. The quoted price can fall even though the company’s factory, workforce and products have not changed during the transaction.
Price therefore reflects:
- the information and beliefs held by market participants;
- the amount buyers and sellers are willing to trade;
- how urgently they want to act;
- available liquidity;
- wider interest rates and economic conditions;
- risk appetite, fear and enthusiasm; and
- the rules and mechanics of the market.
In a deep market, many competing orders can absorb a trade. In a thin market, one order can move the price sharply.
Price and value run on different clocks
Picture price and value as two clocks. The price clock updates with every trade. The value clock changes when the evidence or the assumptions change. Sometimes they move together. Sometimes price races ahead while the value estimate barely moves; sometimes new evidence changes value before enough trades occur to move the displayed price.
Prices react to expectations, not headlines alone
A share price is forward-looking. Buyers are not paying only for the profits already reported. They are paying for what they think the company may produce in future.
That means a result can be good in ordinary language but disappointing relative to the expectation already built into the price.
Consider an illustrative company expected by the market to make twelve million pounds of annual profit. It reports eleven million. That is better than the ten million earned last year, but worse than expected. The share price may fall because the new information makes future assumptions less optimistic.
The reverse can also happen. A company may report a loss, but if investors expected an even larger loss and see evidence of improvement, the price may rise.
The useful comparison is often not good versus bad, but actual versus expected.
This also explains the phrase “buy the rumour, sell the news”. If traders have already bought in anticipation of an event, the eventual announcement may attract few new buyers. Some existing holders may take profits, even when the announcement is positive.
Four different meanings of value
The word value can create confusion because it has several meanings.
Market value is the price buyers and sellers currently agree upon. For a company, multiplying the share price by outstanding shares gives its market capitalisation.
Book value is an accounting measure: broadly, assets minus liabilities. It may be informative for an asset-heavy business but less useful for a company whose advantage lies in people, software, brands or other assets not fully shown on the balance sheet.
Intrinsic value is an estimate based on fundamentals such as future cash flows, earnings, assets, growth and risk. It is subjective because the future is uncertain.
Use value is the benefit an asset provides to its owner. A home, commodity or cryptoasset may be useful in a way that is not captured by a company-style cash-flow calculation.
These measures answer different questions. Quoting one as though it settles all of them creates false precision.
When price and value separate
Price and estimated value can diverge for sensible or foolish reasons.
New information may not be widely understood. A forced seller may accept a low price. A popular story may attract buyers who have not examined the underlying economics. A company may receive little research coverage. Interest rates may change the value investors place on distant future profits. A market disruption may make liquidity more important than analysis.
Sometimes the market is wrong. But an investor who disagrees with the market may also be wrong.
That second sentence matters. Saying “the market has mispriced this” is not evidence. It is a claim that needs a method, assumptions and a reason the gap might eventually close.
An asset below one estimate of value may be a bargain. It may also be a value trap: an apparently cheap asset whose business, finances or prospects are deteriorating faster than the estimate recognises.
An asset above a conventional valuation measure may be overpriced. Or the measure may fail to capture a genuine improvement in growth, resilience or profitability.
Illustrative status: general education, not a personal recommendation.
In practice: build a range, not a target with two decimal places
Suppose an investor values a company by estimating future cash flows.
Instead of producing one number, they can use three scenarios:
- a cautious case in which growth is weak and margins fall;
- a central case based on reasonable continuation of current evidence; and
- an optimistic case in which the company executes well.
The result is a valuation range. The wider the uncertainty, the wider the sensible range should be.
The investor can then ask:
- Which assumptions explain most of the estimated value?
- What evidence would make those assumptions too optimistic?
- Does the current price already require the optimistic case?
- Is the apparent discount large enough to allow for mistakes?
- How liquid is the market if the view changes?
- What event might help other buyers recognise the value, and what if it never occurs?
That allowance for error is sometimes called a margin of safety. It does not make the estimate correct. It acknowledges that it may be wrong.
What price can and cannot tell you
Price can tell you where an asset can currently trade, how the market reacted to new information and, when combined with volume and the order book — the list of waiting buy and sell orders — something about liquidity and demand.
Price alone cannot prove that an asset is cheap, expensive, safe or suitable.
A fall from ten pounds to five pounds does not automatically create value. If the business is now worth less than five pounds, the lower price may still be high. A rise does not prove that the buyer’s reasoning was sound; it only shows that the market moved in their favour.
The useful conclusion
Market price is a transaction fact. Value is a judgement.
Prices change as buyers and sellers respond to expectations, news, liquidity and their own needs. Value estimates change when evidence or assumptions change. The two may converge, but there is no timetable and no guarantee that one investor’s estimate is the destination.
The practical discipline is to know which statement you are making.
“The share trades at five pounds” is observable.
“The share is worth eight pounds” is an argument. It needs evidence, assumptions and room for error.
