All or None

This is an instruction you can give your broker when placing a buy or a sell order. This instruction ensures that your order will be filled in its entirety or not at all. This prevents having a partial execution of your trade.

Write

To write an option is to sell an option. The person who sells the option is considered to be the writer.

Yield

This is the measure of the return on an investment and is shown as a percentage. A stock yield is calculated by dividing the annual dividend by the stock’s current market price. For example, a stock selling at $50 and with an annual dividend of $5 per share yields 10%. A bond yield is a more complicated calculation, involving annual interest payments, plus amortizing the difference between its current market price and par value over the life of the bond.
