Clean vs. Not-So-Clean Energy

While I have not mentioned it much on the blog, one of my favorite sectors to invest in is the energy sector. When it comes to energy ETFs, the 800 pound gorilla is XLE, the energy select sector SPDR that trades over 20 million shares on a typical day. XLE’s holdings are heavily tilted toward the major integrated oil companies, with Exxon Mobil (XOM) and Chevron (CVX) accounting for slightly more the 1/3 of the ETFs holdings, followed by ConocoPhillips (COP), Schlumberger (SLB), Occidental Petroleum (OXY), etc.

With cap and trade legislation passing the House over the weekend, investing in the energy space is getting even more interesting. XLE is up this morning, as are the popular oil services ETF, OIH (the top five holdings favor drillers and include RIG, SLB, DO, BHI and NE) and the exploration and production ETF, XOP (top five holdings are XEC, PXD, EAC, INT and HK.)

There are a variety of ETFs out there in the clean/green space. Perhaps the best known of these and certainly the most popular is PowerShares WilderHill Clean Energy (PBW), whose largest holdings include a healthy dose of solar companies (top five holdings are FSYS, VLNC, SOLR, ESLR, SOL.) Among the more interesting alternatives is a sibling ETF, PowerShares WilderHill Progressive Energy (PUW), which places more emphasis on energy efficiency and nuclear power and has a list of top holdings which includes MX.TO, ES, PX, USU and CCO.TO. For a solar-only ETF play, Claymore/MAC Global Solar Energy (TAN) is an excellent bet. Note that many of the holdings of TAN are not traded on U.S. exchanges. The current top five holdings are MBTN.SW, FSLR, S92.BE, CTN.DU and SWV.BE. Also in the top ten holdings are two Chinese solar companies whose ADRs are available in the U.S.: STP and TSL.

In the chart below, I have highlighted my favorite all-purpose clean energy ETF, PBW and have included a ratio of PBW to XLE in order to get a sense of the relative performance of clean energy with respect to the broad energy sector. While PBW has pulled back with the broader market during the past three weeks, it has continued to perform strongly against the broad energy sector ETF. As the ratio chart hints at, pairs trades involving clean energy ETFs such as PBW, PUW and TAN vs. XLE, XOP and OIH are one way to play the Washington energy legislation game going forward.
