Another day of pain for energy stocks

• Energy stocks are slammed across the board as oil prices take another nosedive (I, II), with the losses heaviest on shares of small, U.S.-based oil and gas producers.
• “Financial leverage is being thrown out the window, and everything else is being purged as well,” says Simmons analyst Bill Herbert, who adds that cuts to production budgets in the coming year likely will mean more pain for oil service companies.
• Among the hardest-hit shares: TPLM -15.2%, CRK -12.4%, GDP -11.9%, NOG -9.5%, AREX -8.6%.
• Investors have been less quick to dump shares of integrated oil companies, but today they have been smacked too: XOM -2.8%, CVX -2.9%, COP -2.3%, BP -2%, RDS.A -2.2%, TOT -2.3%.
• Today's worst performers on the S&P 500 include OKE -8.2%, DNR -7.4%, NE -5.6%.
• Service companies also are down: SLB -2.6%, HAL -2.7%, WFT -6.6%, BHI -2%.
• ETFs: XLE, ERX, VDE, OIH, ERY, DIG, DUG, IYE, XES, IEZ, PXI, FENY, PXJ, RYE, FXN, DDG
