Net change is the difference in an asset’s closing price from one day to the next. It is a commonly used method of quoting the price movements of stocks and funds.
Net change can be displayed as either a positive or negative, or, on rare occasions, neutral, depending on the direction of the price movement. The impact of a dividend payment or stock split is negated when displaying net change.
Calculating net change is simple: take the current day’s closing price away from that of the previous day for any particular asset. If Vodafone closes at 250p today, after closing at 255p the previous day, then its net change is -5p.
