A market correction and a market crash both refer to significant declines in stock prices, but they differ in severity, speed, and market impact. Understanding these differences helps investors manage risk and respond appropriately during market downturns.

A market correction is generally defined as a decline of 10% to 20% from a recent market peak. Corrections occur fairly regularly and are considered a normal part of the market cycle. They often happen when stocks become overvalued or when investors react to economic news such as interest rate changes, earnings reports, or geopolitical events. Corrections usually develop gradually and may last for a few weeks or months. In many cases, markets recover relatively quickly once prices adjust to more realistic valuations.

In contrast, a market crash is a much more severe and sudden decline, typically involving a drop of more than 20% in a very short period of time, sometimes within days. Crashes are often driven by panic selling, financial crises, economic shocks, or the bursting of speculative bubbles. Investor fear spreads quickly, leading to massive sell-offs and extreme volatility. Famous examples include the Wall Street Crash of 1929 and the Black Monday (1987).

Another key difference is market psychology. During corrections, investors usually remain relatively calm and view the decline as temporary. During crashes, however, panic and uncertainty dominate the market. While corrections are common and healthy adjustments, crashes are rare but can have serious economic consequences and take much longer for markets to recover.
