What's the difference between stock index options and stock index futures?
1 Stock index option is the right of securitization, while stock index futures is only a trading method.
When trading, the option buyer does not need to pay the deposit, but both the buyer and the seller of futures need to pay the deposit.
The option is in a nonlinear profit and loss state, and the buyer's loss is limited, and the seller's income is limited; Futures are in a linear profit and loss state, and investors bear the same risks and benefits.
Stock index option is a one-way contract, the buyer has the right and the seller only has the obligation; Futures is a two-way right, and both long and short parties can ask the other party to perform.
