WDCWestern Digital Corp+ 5.80%− 11.33%

A single series is normalized to its own start, so it says nothing beyond one line leaving zero.

Period Return

Each series is converted to a percentage of its own starting point, so all of them begin at zero. What is compared is the return over the period, not price levels.
