<p>A market correction is a decline of 10% or more in the price of a security, index, or basket of assets from its most recent peak. Corrections are common in equity markets and serve as a natural mechanism for adjusting overvalued prices back toward longer‑term trends. While less severe than a <a href="/NewSite/encyclopedia/bear-market/" class="ency-link">bear market</a>—which typically involves a 20% drop—corrections can still signal shifting investor sentiment and prompt tactical portfolio adjustments.</p>

<h2>How It Works</h2>
<p>Corrections are identified by comparing the current price level to the highest closing price reached over a defined look‑back period, often the past 52 weeks. When the price falls below 90% of that peak, the threshold for a correction is met. The decline can unfold over days, weeks, or months and may be driven by macroeconomic data, geopolitical events, earnings disappointments, or changes in monetary policy. Technical traders watch for support levels and volume spikes to gauge whether the correction will stall or deepen into a bear market.</p>
<ul>
<li>Peak identification: recent high price over chosen period.</li>
<li>Threshold test: current price ≤ 90% of peak.</li>
<li>Duration: correction ends when price rebounds above the 10% decline level or continues falling.</li>
<li>Indicators: moving averages, RSI, and volume help confirm momentum.</li>
</ul>

<h2>Why It Matters</h2>
<p>For investors, corrections create both risk and opportunity. They can erode short‑term portfolio values, prompting a review of asset allocation and risk tolerance. Conversely, disciplined investors may use corrections to buy quality stocks at lower prices, positioning for future growth when the market rebounds. For example, during the early 2022 equity correction, the S&P 500 fell roughly 12% from its January high; investors who added to diversified ETFs on the dip captured gains as the index recovered later that year. Recognizing the signs of a correction helps investors avoid panic selling and maintain a long‑term focus aligned with their financial goals.</p>
