# IWM Declines 1.41% as Small Caps Underperform

## The Take
- Consider your risk tolerance and investment goals when evaluating companies based on their market capitalization.

_A look at market capitalization and why it matters for investors._

Markets are signaling something important today. While the broader market remains near all-time highs, the IWM, representing small-cap stocks, is down 1.41%. This divergence highlights the concept of market capitalization, a key factor for investors to understand.

Market capitalization, or "market cap," is the total value of a company's outstanding shares of stock. It's calculated by multiplying the share price by the number of shares outstanding. Companies are often categorized by market cap: large-cap, mid-cap, and small-cap. Large-cap companies are generally more stable, while small-cap companies may offer higher growth potential but also come with greater risk. The IWM's decline today suggests that investors may be rotating away from riskier small-cap stocks.

Understanding market cap helps investors diversify their portfolios and align their investments with their risk tolerance. Keep these levels in mind as you navigate today's session.
