<h2>Operating Margin: A Key Risk Indicator</h2>
<p>The <strong>operating margin</strong> is a crucial profitability ratio used to assess a company's operational efficiency. It measures the proportion of revenue that exceeds operating expenses, excluding interest, taxes, and depreciation. In other words, it represents the profit generated from core business activities.</p>

<h2>How It Works</h2>
<p>The operating margin is calculated by dividing operating income by revenue:</p>
<table>
<tbody>
<tr>
<th>Operating Margin</th>
<th>=(Operating Income) / (Revenue)</th>
</tr>
</tbody>
</table>
<p>Operating income is typically found on a company's income statement and is calculated as:</p>
<table>
<tbody>
<tr>
<th>Operating Income</th>
<th>= (Revenue - Operating Expenses)</th>
</tr>
</tbody>
</table>
<p>Operating expenses include costs such as salaries, rent, and raw materials. A higher operating margin indicates better operational efficiency, while a lower margin suggests higher operating costs relative to revenue.</p>

<h2>Why It Matters for Traders</h2>
<p>The operating margin is a vital metric for traders as it provides insights into a company's ability to generate profits from its core operations. A consistently high operating margin may indicate a strong business model, while a declining trend could signal increasing competition or rising costs. Here's why it matters:</p>
<ul>
<li><strong>Profitability assessment</strong>: It helps evaluate a company's profitability by focusing on its core operations.</li>
<li><strong>Comparative analysis</strong>: It enables comparison of a company's operational efficiency with its peers or industry averages.</li>
<li><strong>Risk identification</strong>: A persistently low or declining operating margin may indicate increased risk, such as intensifying competition or rising costs.</li>
</ul>

<h2>Example</h2>
<p>Consider two companies, Apple Inc. (AAPL) and Samsung Electronics (SSNLF), both operating in the technology sector. In 2021, AAPL reported an operating margin of 34.33%, while SSNLF reported 21.35%. This suggests that AAPL was more operationally efficient than SSNLF in 2021.</p>
