January 6, 2015 (Chinavestor) Oil prices drive two sectors, but to a different direction. This creates tremendous opportunity for the intelligent investor. During times when oil price creeps higher, investors should own stocks like Whiting Petroleum (NYSE:WLL) and Continental Energy (NYSE:CLR). When oil enters bear markets, investors should sell shale oil stocks and swap them to airliners. Here comes the logic. When oil prices increase, oil developers do well at the expense of airliners. But when price of oil falls, oil producers suffer but airliners shine. To illustrate how much the price of oil effects these sectors, we are going to pull two charts. One is for the short term, just three days. The other is for long term, 10 years. And to make the point better, we chose an oil producer that is EXTREMELY sensitive to oil prices: shale oil companies. Whiting Petroleum (NYSE:WLL) is the largest Bakken shale play and is an excellent stock to study price volatility. For airliners, we chose China Eastern Airlines (NYSE:CEA), China's second largest carrier by fleet size. This is also a volatile stock.
