Nations Learning Center
Learn to read what the options market is pricing — from first principles to dealer-flow mechanics — across 189 lessons and case studies.
What implied volatility is
Implied volatility is the market’s forecast of how much a stock or ETF is likely to move, backed out of the prices investors are paying for its options. When options grow more expensive, implied volatility rises — traders are paying up for protection or upside because they expect bigger moves; when options cheapen, it falls. Unlike historical volatility, which measures what already happened, implied volatility is forward-looking: it is what the options market expects next.
Each Nations index isolates one precisely-defined slice of that signal — the at-the-money level (VolDex®), the cost of upside calls (CallDex®) and downside puts (PutDex®), the balance between them (RiskDex®), and the price of tail-risk protection (TailDex®) — so you can read exactly what options are pricing across the whole family.
