What is a market correction?
A market correction is a fall in the price of a stock, index, commodity or currency pair from its most recent peak. It is clearly deeper than normal daily swings but not deep enough to count as a bear market.
Financial media usually use a fixed percentage decline from the peak as the threshold for calling a move a "correction". That figure is a convention, not a rule set by any exchange or regulator. When you read the term, check which threshold the source is using.

How a correction is measured: a hypothetical example
This example uses letters instead of real prices.
- An index reaches a peak closing level P.
- Over the following weeks it falls to a low closing level L.
- The decline is (P − L) ÷ P, shown as a percentage.
If that percentage is at or above the threshold the source uses, commentators call the move a correction. If the index then rises back above P, the correction is over. If it keeps falling past the bear-market threshold, reports usually stop calling it a correction and call it a bear market.
You can do the percentage step with any percentage calculator, including those on our calculators page.
Where you see the term
- News and headlines: "the index entered correction territory" means the fall from the peak has crossed the source's threshold.
- Analyst and fund reports: corrections are counted and dated, for example how long they lasted and how deep they went.
- Trading platforms: MetaTrader 4 and MetaTrader 5 do not label corrections. You see them on the chart as a fall from a swing high. Traders often measure them with the crosshair or Fibonacci tools covered in technical analysis.
Precise definition and edge cases
- Closing vs intraday prices: most index statistics use closing levels. Intraday highs and lows can show a deeper or shallower fall.
- Which peak: some sources measure from the all-time high, others from a recent swing high. The two can give different answers.
- Time correction: some analysts use this term when price moves sideways for a long period without falling far. This is close to consolidation.
- Forex usage: in currency pairs, "correction" often loosely means a pullback against the main trend, with no fixed threshold.
Correction vs crash
A crash is a sudden, very steep fall, usually over days or even hours, often with panic selling. A correction can develop slowly over weeks or months. A fast fall may meet the correction threshold and still be described as a crash because of its speed. See flash crash and circuit breaker for the extreme cases.
Risk note
When you trade indices or other markets as leveraged CFDs, a correction can cause large losses quickly, and positions can be closed at a stop-out. Read risk management before trading in falling markets.

Frequently asked questions
What does market correction mean in simple words?
It means a market has fallen noticeably from its recent high, but less than the fall needed to call it a bear market.
Is a stock market correction the same as a crash?
No. A crash is defined mainly by speed and steepness. A correction is defined by the size of the fall from the peak, however fast it happens.
Who decides that a correction has started?
No official body decides it. Journalists and analysts apply their own conventional threshold to closing prices, so different sources can disagree.
Does a correction always turn into a bear market?
No. Many corrections end when prices recover to a new high. Whether one deepens cannot be known in advance.
