Why has the Distributed Energy Stock Index outperformed other indices and the stock market as a whole? An EnergyPulse article written by CEO Jamie Wimberly offers answers. Three years have passed since DEFG LLC launched its benchmark stock index, the DESI, to track the progress of the clean and alternative energy technology (clean tech) sector. DESI is comprised of 40 publicly traded companies, organized into six segments that represent the spectrum of companies in the clean tech sector. The DESI has performed very well over the past three years, recording an overall gain of 52 percent. The DESI has outperformed the S&P 500 and Russell 2000 by wide margins, and done well in comparison to other clean/alternative energy indices.
