DEFINITION of 'Change'

1. For an options or futures contract, the difference between the current price and the previous day's settlement price.

2. For an index or average, the difference between the current value and the previous day's market close.

3. For a stock or bond quote, the difference between the current price and the last trade of the previous day.


For investors, change is good - even downward plunges are needed once in a while. A market without change is basically a bank account, and interest rates rarely stay ahead of inflation rates.
