Breakout for Energy ETFs?

Posted 10/16/2009 2:56 p.m. EDT

Gasoline inventories declined by 5.2 million barrels last week, while analysts had expected an increase.

Crude oil inventories increased by 0.4 million barrels, but it was overshadowed by the big decline in gasoline and a smaller decline in distillates, which includes heating oil.

Refinery utilization is down for maintenance and that could mean a few more weeks of inventory declines. Nevertheless, gasoline inventory is 15.4 million barrels above 2008 levels at this time, distillates are 48.6 million barrels above last year's levels, and crude oil inventories are 29.6 million barrels higher.

Equity investors followed the pop in oil yesterday by pushing up the price of energy ETFs. Energy Select SPDR ( XLE) gained 2% to close at its highest level since October 2008.

Shares of refiner Tesoro ( TSO) gained 8.6%, and Valero ( VLO) advanced 7.1%.

iShares Dow Jones U.S. Oil & Gas Exploration & Production ( IEO) is the ETF with the largest exposure to TSO at 0.83%; it gained 1.9% yesterday. IEO also has the largest exposure to VLO, at 3.02%.

We've seen natural gas, crude oil and now gasoline jump and plunge based on large, unexpected swings in inventories. It is partially due to economic data that provides a mixed picture of the economy, along with huge amounts of liquidity created by the Federal Reserve.
