No, that's not what I said. When I say "risk premium" it's a generic term for "little extra" you'd have to pay to protect yourself in the market.Quote from just21:
So you sell high implied volatility out of the money and hedge it with low at the money implied volatility?
To name a few, just in an index, it could be gamma (straight-forward option convexity), term structure (additional slope of the term structure to compensate for future shocks), short-dated skew (response of realized volatility to market direction), long-dated skew (cost of spot-vega convexity) etc.
The idea is that you find which risk premium is overpriced against another risk premium and what ratio to trade one against the other. Let's take an example - you might want to sell short-dated ATM volatility and buy long-dated skew against it in some sort of ratio (usually, the ratio would be such that spot-vega convexity would protect you from the realized gamma moves). You are actually taking a view (yes, PREDICTING) that short-dated gamma is overpriced against dVega/dSpot convexity and hopefully you'd have some sort of a smart statistical model to tell you so.
Once you develop the relative value thought process, you find that these trades/strategies are fairly easy to construct and evaluate with some simple statistics and some common sense.
if you can share your other "hedge" ideas here , it is appreciated.
