This is a survey of the biggest winners, on a percentage basis, over a number of time-spans. Below I have created galleries in SlopeCharts of the best gainers for 2019, the past five years, the past ten years, and the past twenty years. I want to emphasize two things: (1) even though I just told you, I’ll say again these are percentage charts, not normal charts; (2) if you want to see the big version of any chart, click on the thumbnail. Unfortunately, the left/right arrows don’t let you navigate the entire set, so you need to click on any specific chart to see it.
