How EMA iv/hv history Data Feeds Strategy Selection
Strategy selection on Emera Incorporated options does not derive from any single metric in isolation. The iv/hv history view above sits inside a broader read: ATM IV currently sits at 34.0% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. Combine the iv/hv history data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

Frequently asked EMA iv/hv history questions
- Is EMA options pricing rich or cheap right now?
- As of May 15, 2026, Emera Incorporated (EMA) ATM IV is 34.0% against 20-day realized volatility of 13.4%. IV rank is 8.6%. EMA options are pricing in more volatility than the stock has recently realized: a positive variance risk premium worth 20.6 vol points.
- What is the EMA variance risk premium?
- The variance risk premium is the persistent gap between implied and subsequently realized volatility. In equity markets it averages positive because option sellers demand compensation for bearing variance shocks. EMA is currently priced consistently with this premium, which is one input to whether short-vol or long-vol structures carry their typical edge.
- What does EMA IV rank mean for strategy selection?
- IV rank normalizes the current ATM IV to its 1-year range: 0% is the low, 100% is the high. EMA's current rank of 8.6% signals where current pricing sits in its own 1-year history. High-rank regimes typically favor premium-selling structures (credit spreads, condors, covered calls); low-rank regimes typically favor premium-buying or long-volatility structures.
