Out-of-the-money Option
An Out-of-the-money Option is when, during trading, the option is worth less than was paid for it. For example, you predict that the price of an asset will rise, but it falls. Your forecast doesn’t come true and you lose money on the option. The option can fluctuate in and out of the money: i.e. be profit making (in-the-money) at one point and loss making (out-of-the-money) at another before the option expires.
