Volatility & derivatives arbitrage
Trade the gap between implied and realized volatility.
Anatomy of the strategy
Trade the gap between implied volatility and realized volatility, and exploit structural mispricings in options and convertibles.
Delta-hedged option portfolios capture volatility risk premium; convertible bonds are decomposed into bond + option legs for relative-value trades.
Structural risk transfer between option buyers and sellers; mathematical pricing edges.
Tail gaps, liquidity spirals, and model calibration error — losses concentrate exactly when hedging is hardest.
How the desk runs it
A loop, not a tip — the same four steps, every day, without exception.
Map the vol surface
Implied volatility across strikes and tenors forms a surface. Its shape — skew, term structure — reveals where options are rich or cheap.
Price the truth
Proprietary models estimate what volatility will actually realize. The trade is the gap between that estimate and what the market implies.
Hedge the direction away
Delta-hedging strips out the bet on direction, isolating the volatility bet. What remains is a pure long- or short-vol position.
Manage the tails
Vol strategies die in the tails. Position limits, gap stress tests, and liquidity budgets decide whether the desk survives its worst day.
