SVI Parameterization
SVI Parameterization — Arbitrage-aware parameterization of volatility smiles for interpolation and trading.
Definition
SVI Parameterization refers to arbitrage-aware parameterization of volatility smiles for interpolation and trading. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
Options and futures embed views on vol, skew, and path that cash markets only hint at. When arbitrage-aware parameterization of volatility smiles for interpolation and trading shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what svi parameterization is saying. If arbitrage-aware parameterization of volatility smiles for interpolation and trading moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
State the expiry and Greek exposure; unmarked vol or pinning effects rewrite the thesis. Prefer a short written null hypothesis for SVI Parameterization: what would falsify the current reading in the next window?
