Market observers believe the sector can continue its recent rebound. Current OPEC compliance with production cut plans remains above their historical average, and it usually takes between two to three quarters for inventories to normalize after the cuts. The challenge for energy equities is that some oil market observers see more declines coming for crude. Oil traders are concerned over how fast U.S. shale oil producers will increase production to capture the rising prices.

“While the forward price to earnings ratio (PE) of the energy index at nearly 24 is well above the 18.6 for the S&P 500, that number is set to decrease as the sector has the second highest percentage of upward estimate revisions of the major S&P groups through Thursday morning,” according to Reuters.

Dow components Exxon and Chevron, the two largest U.S. oil companies, combine for about 40% of cap-weighted energy ETFs, such as XLE, the Vanguard Energy ETF (NYSEArca: VDE), iShares U.S. Energy ETF (NYSEArca: IYE) and the Fidelity MSCI Energy Index ETF (NYSEArca: FENY).
