This ETF tracks an index that is comprised of common stocks of U.S. energy companies that are principally engaged in the business of producing, distributing or servicing energy related products, including oil and gas exploration and production, refining, oil services, pipeline, and solar, wind and other non-oil based energy. For decades, our nation, as well as the majority of the developed world, have been dependent on the use of fossil fuels as our primary means of energy. But at some point in the future, sources will begin to dwindle, and the world will be forced to adopt a new energy strategy, in order to cope for the losses that the non-renewable fossil fuel industry will inevitably see. As one of the largest consumers of oil in the world, the U.S. may be faced with this problem sooner than other nations. PSCE will give investors exposure to a wealth of small cap companies who have their hands in alternative forms of energy, any of which could become the next big producer for the country. For now, the ETF still gives investors healthy exposure to small cap oil-based firms, while also creating an upside potential with holdings based in alternative energy.
