As a result, under normal market conditions, the arbitrageur expects the combined position to be insensitive to small fluctuations in the price of the underlying stock.

The Greeks are vital tools in risk management.Each Greek measures the sensitivity of the value of a portfolio to a small change in a given underlying parameter, so that component risks may be treated in isolation, and the portfolio rebalanced accordingly to achieve a desired exposure; see for example delta hedging.

If one is to implement an effective tail risk hedging program, one has to begin by carefully defining tail risk, i.e. by identifying elements of a tail event that investors are hedging against. A true tail event should exhibit the following three properties simultaneously with significant magnitude and speed: falling asset prices, increasing ...
