The Performance indicator displays a security's price
performance as a percentage. This is sometimes called a "normalized" chart.
The Performance indicator displays the percentage that
the security has increased since the first period displayed. For example, if the
Performance indicator is 10, it means that the security's price has increased 10% since
the first period displayed on the left side of the chart. Similarly, a value of -10% means
that the security's price has fallen by 10% since the first period displayed.
Performance charts are helpful for comparing the price
movements of different securities.
The following chart shows a Performance indicator:
The Performance indicator is calculated by
dividing the change in prices by the first price displayed.
