Gasoline in the US continues its weeks-long descent with prices down about 13 cents a gallon over last week to $2.544, which is lower by around 69 cents/gallon from this time last year, according to the US Energy Information Administration. Many drivers are welcoming the lower bills at the gas station as a fantastic holiday gift, but Ford investors are somewhat spooked over the potential sales implications for the2015 F-150.

Market analyst Rod Lache of Deutsche Bank recently downgraded Ford's stock from a buy to hold, according to TheDetroitBureau.com, and his report to investors may have played a part in a drop in the company's share price. Lache praised the truck's powertrain and lightweight technology, but wrote, "We question whether consumers will pay the price for this content with $2-$3 gas," in his report, according to the website.

Whether buyers actually turn away from the F-150 is mostly speculative at this point because it only recently began production. With around 700 pounds of weight loss thanks in parts to its new aluminum parts, the latest Ford pickup offers up to 26 miles per gallon on the highway, plus segment-best payload and towing ratings. Prices are up somewhat in part to pay for additional standard features, though.

Still, any further dip in Ford's stock is bad news this year. According to TheDetroitBureau.com, the company's shares are down about 7.5 percent this year. On December 15, the price fell to $14.28, the lowest since November 10.
