A related term, delta hedging, is the process of setting or keeping a portfolio as close to delta-neutral as possible. In practice, maintaining a zero delta is very complex because there are risks associated with re-hedging on large movements in the underlying stock's price, and research indicates portfolios tend to have lower cash flows if re ...
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. However, maintaining a market-neutral position may require rebalancing transactions, a process called dynamic delta hedging. This rebalancing adds to the return of convertible ...
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.

A major task of the XVA-desk, therefore, [4] [24] is to hedge [13] this exposure; see Financial risk management § Banking. This is achieved by buying, for example, credit default swaps: this "CDS protection" applies in that its value is driven, also, by the counterparty's credit worthiness.
The hedging here focuses on addressing changes to the counterparty's credit worthiness, offsetting potential future exposure at a given quantile. Further, since under Basel III , banks are required to hold specific regulatory capital on the net CVA-risk, [ 5 ] the CVA desk is responsible also for managing (minimizing) the capital requirements ...
