With the holiday weekend, investors should take the opportunity to relax and rest up from the grind of the stock market. For those with some time, lets focus on oil reaching $50/bbl for this weeks version of the Weekend Research that will be split into 2 posts. This version will focus on the sectors that will benefit from a peak in oil prices at this price as E&Ps start pumping more oil. A couple of beaten down sectors are retailers and airlines. The next version for focus on those stocks that will benefit from oil stabilizing, if not rising from the $50 level. The retail category is a mixed bag with the Retail ETF (RTH) trading close to the highs as discount retails surge while luxury brands and department stores struggle. While unclear whether Macy's (M) or Kohl's (KSS) benefits to any great degree by lower fuel prices, the stocks generally trades opposite the price of oil. Both stocks trade at less than 10x EPS estimates while paying dividend yields of around 5% The other category that definitely directly benefits from lower oil prices are the airlines. At this point, almost all airline stocks are unilaterally cheap after not benefiting from the collapse in oil prices. A few top picks include, legacy airline American Airlines Group (AAL) trading an absurdly low 5x EPS estimates while budget airline Spirit Airlines (SAVE) and top regional airline Alaska Air Group (ALK) trade at roughly 9x EPS estimates. Alaska Air is in the middle of a merger with Virgin America (VA) that makes it a stronger and more profitable provider on the west coast. All of these stocks will benefit from lower fuel prices and are cheap stocks regardless. If your thesis is that oil prices continue higher, wait for version 2 of the Weekend Research.
