in 6 months its been high as 75 and low as 59..which clearly indicates that u can buy the stock for short term to gain 10 to 15 percent profit and then short sell for a month as that we see in the chart as it has made a lower low (ps: yes and do put stop loss) . the demand for the oil will decrease eventually on a longer run but not a lot , as now a days because of the battery based automobile .
