<p>Market risk, also known as systematic risk, is a fundamental concept in finance that refers to the potential for losses due to factors that affect the entire market or a large segment of it. It's distinct from idiosyncratic risk, which affects individual assets or companies. Market risk is a key consideration for traders, as it can significantly impact their portfolios regardless of the specific assets they hold.</p>

<h2>How It Works</h2>
<p>Market risk operates at a macro level, driven by factors such as interest rates, inflation, economic growth, geopolitical events, and market sentiment. These factors influence the overall market conditions, leading to price movements in various assets. Here's how it works:</p>
<ul>
  <li><strong>Market-wide trends</strong>: When the market is bullish, most assets tend to rise in value, and vice versa. This is due to investors' collective optimism or pessimism.</li>
  <li><strong>Sector-specific trends</strong>: Sometimes, market risk can be sector-specific. For instance, a slowdown in the tech sector might lead to a decline in tech stocks, even if other sectors are performing well.</li>
  <li><strong>Systematic factors</strong>: Market risk is often influenced by systematic factors, such as changes in monetary policy or global economic indicators. These factors affect all assets in a predictable way.</li>
</ul>

<h2>Why It Matters for Traders</h2>
<p>Understanding and managing market risk is crucial for traders. Here's why:</p>
<ul>
  <li><strong>Portfolio diversification</strong>: While diversification can help mitigate idiosyncratic risk, it doesn't protect against market risk. Traders need to consider the overall market conditions when building their portfolios.</li>
  <li><strong>Risk management</strong>: Traders should use tools like stop-loss orders to limit potential losses from market downturns. On STB Provider's MetaTrader 5 platform, traders can set stop-loss orders with ease.</li>
  <li><strong>Opportunity identification</strong>: By understanding market risk, traders can identify opportunities. For instance, they might buy assets when the market is oversold and sell them when the market recovers.</li>
</ul>

<h2>Example</h2>
<p>Let's consider the 2008 financial crisis. This event was a prime example of market risk. The subprime mortgage crisis in the U.S. led to a global market downturn, affecting virtually all asset classes. Traders who didn't account for this market risk suffered significant losses, regardless of the specific assets they held.</p>
