Want to compare the performance of two or more stocks, indices or mutual funds? Our interactive PerfCharts tool is just the ticket. PerfCharts display price performance lines for up to ten different data sets. You control the start and end dates for the comparison, using an interactive date “slider” at the bottom of the chart. John Murphy uses PerfCharts to examine intermarket relationships. These powerful charts can also be useful for gauging relative performance, sector rotation and much more.
