The formula to estimate a partial change in an option's price based on the change in the underlying asset's price is primarily dependent on the option's Delta. Delta represents the sensitivity of the option's price to changes in the price of the underlying asset. Therefore, the most straightforward and widely used formula to estimate this partial change is:

Partial change in option price=Δ×Change in underlying pricePartial change in option price=Δ×Change in underlying price

This formula directly utilizes Delta to measure the immediate rate of change in the option's price relative to a small change in the underlying asset's price. The other options involving Gamma are more complex and not typically used for simple partial changes.

Derivatives have several advantages over cash instruments in hedging transactions. These include:

Lower Credit Risk:

Derivatives, especially exchange-traded ones, often have lower credit risk because the clearinghouse guarantees the performance of the contract.

Lower Funding Requirements:

Derivatives typically require lower upfront capital than buying or selling the underlying cash instruments directly. This is due to the leverage they offer, where only a margin is required instead of the full value of the position.

Lower Dealing Costs:

Trading derivatives can be cheaper in terms of transaction costs compared to trading the underlying cash instruments. This is especially true for large positions or frequent trading.

Lower Capital Charges:

Regulatory capital requirements for derivatives can be lower compared to cash instruments because derivatives can be used to hedge and reduce overall portfolio risk, thereby reducing capital charges under regulatory frameworks.

In a single-name Credit Default Swap (CDS), the protection seller (who assumes the credit risk) often posts collateral to the buyer to mitigate counterparty risk. The amount of collateral is typically determined by:

Credit standing of the protection seller:If the seller’s creditworthiness declines (e.g., lower credit rating), more collateral is required to secure the buyer against the seller’s potential default.
