What can you add to or highlight out of the following explanation of a derivative?

The term derivative refers to a financial product that derives its value from its relationship to another underlying asset (bonds, stocks, currency, commodities, etc.). Derivatives that are often used in finance are futures, forwards, swaps, and options. Banks often utilize derivatives because they are useful for them, although there are risks that come along with the use of derivatives. For example, the cause of the housing crisis can be tied back to the use of derivatives. Derivatives allow the parties to take ownership of assets with minimal investment, they allow for transferring risk, and speculating in the market which can lead to high rewards. But derivatives are also very risky due to various factors like market volatility, economic instability, etc. One type of derivative that would be useful for a financial institution would be futures. A futures derivative is an agreement between two parties to buy or sell the commodity or financial instrument at a predetermined price on a specified date. Futures are very useful for financial institutions because they are highly regulated and organized. They are standardized contracts traded at an established exchange. The seller and buyer must sell or buy the asset at the set price, regardless of what the current market price ends up being at the expiration date. This can mean that the seller ends up missing out if the market changes favorably. But they typically only require a small deposit and can hedge the price of movement which helps to prevent losses from price changes which reduces risk.
