"There are two political footballs to keep your eyes on: health care and energy," Stephen Guilfoyle, chief market economist at Stuart Frankel & Co., wrote in a note. "Depending on who appears to come out on top tonight could provide direction to these two sectors. Energy is a regulation play, while health care becomes about the perceived success or failure of Obamacare. These two candidates have very different ideas on these two areas, and an upper hand on Tuesday morning for either candidate could provide movement."
The health care sector was the worst performer on markets Monday. The industry's largest players including Johnson & Johnson (JNJ) , Merck (MRK) , Amgen (AMGN) , Gilead Sciences (GILD) and AbbVie (ABBV) were all lower, while the Health Care SPDR ETF (XLV) slid 1.2%.
Pfizer (PFE) fell nearly 2% after opting against splitting into two publicly traded companies.

Crude oil prices moved higher ahead of the three-day International Energy Forum. Major oil producers, including energy ministers from Organization of Petroleum Exporting Countries will convene in Algeria from Monday to Wednesday to debate solutions to the current oil crisis. A production freeze, rather than an output cut, looks like the most likely solution for producers to agree on. An agreement has so far been out of grasp with producers wary to cede market control even as prices tanked.
"Market participants will be looking for clues on whether Saudi Arabia and Iran are likely to come to an agreement with each other and some non-OPEC producers about curbing crude oil supply," said Fawad Razaqzada, technical analyst at FOREX.com. "The outcome of these meetings could have significant consequences for oil prices, which in turn should have strong influence on the direction of energy stocks."
West Texas Intermediate crude oil gained 2.70% to $45.68 a barrel on Monday.
