📈 What Are Market Shocks?

❓ Frequently Asked Questions

What constitutes a "market shock"?

A market shock is defined as a daily price movement that exceeds typical volatility patterns. We focus on negative shocks - significant single-day declines.

How is the S&P 500 comparison useful?

Comparing individual stock shocks with the broader market helps identify whether declines are stock-specific or part of broader market movements.

What time period should I analyze?

For comprehensive analysis, we recommend 3-6 month periods. Shorter periods may not capture enough data, while longer periods might include outdated market conditions.

Are these real-time market shocks?

Yes, all analysis is based on actual historical price data from reliable market sources.
