How to Read Volatility Context
This page compares realized movement with options pricing so you can judge whether premium looks rich or cheap.
What the comparison means

Historical volatility shows what the stock has actually done, while implied volatility shows what options are currently charging for future movement.

How traders use it

When IV sits above realized movement, premium sellers often pay attention. When realized movement catches up or exceeds IV, buyers get a stronger case.

What can trap you

Expensive options can still get more expensive into catalysts, and cheap-looking options can stay cheap when realized movement dries up.

Rich or cheap is a pricing read, not a directional signal by itself.
