PowerShares Energy Trust Leads Rebound in Commodity Trusts
The chart below shows six commodity group ETFs from PowerShares. The Silver Trust (DBS) and Precious Metals Trust (DBP) are the weakest year-to-date, while the Energy Trust (PBE) and Oil Trust (DBO) the only ones with gains, albeit small gains. These year-to-date gains stem from strength in Natural Gas ($NATGAS) and the recent rebound in West Texes Intermediate ($WTIC).
