1. Stock index futures hedging. Hedging of stock index futures refers to the behavior of taking advantage of the unreasonable price of stock index futures market, participating in the trading of stock index futures and stock spot market at the same time, or trading stock index contracts with different maturities and different (but similar) categories at the same time to earn the difference. Arbitrage of stock index futures can be divided into cash hedging, intertemporal hedging, cross-market hedging and cross-variety hedging.

2. Commodity futures hedging. Similar to the hedging of stock index futures, commodity futures also have hedging strategies. When buying or selling a futures contract, they sell or buy another related contract and close both contracts at a certain time.

3. Statistical hedging. Different from risk-free hedging, statistical hedging is a kind of risk arbitrage by using the historical statistical law of securities prices, and its risk lies in whether this historical statistical law will continue to exist in the future.

3. Option hedging. Option, also known as option, is a derivative financial instrument based on futures. The essence of option is to price the rights and obligations in the financial field separately, so that the transferee of the right can exercise his right to trade or not to trade within a specified time, and the obligor must perform it.
