IWM Options FAQ

Why trade IWM options instead of SPY?

IWM has higher IV (more premium), greater rate sensitivity (macro trading), and different sector composition (less tech, more financials/industrials). Many traders sell IWM premium because the higher IV provides better risk-reward.

How does IWM relate to interest rates?

Small caps are heavily reliant on bank lending and variable-rate debt. Rate cuts are bullish for IWM; rate hikes are bearish. FOMC decisions create significant IV events and directional moves in IWM options.
