/sprɛd ˈɑpʃən/ – Phrase
Definition: mua bán song hành hợp đồng quyền chọn.
A more thorough explanation: A spread option is a type of financial derivative contract that gives the holder the right, but not the obligation, to buy or sell an underlying asset at a specified price within a specified time period. The difference between the strike price and the market price of the underlying asset at the time of exercise determines the payoff to the option holder.
Example: In the spread option offense, the quarterback has the option to either hand off the ball to a running back or keep it and run with it himself.
