Wall Street Journal: Auto Industry’s Ranks of Electric-Car Battery Suppliers Narrow

Luxury car maker Audi AG on Wednesday revealed its first all-electric car would go 310 miles on a charge using an advanced battery developed by South Korea’s LG Chem Ltd. and Samsung SDI Co., two of three Asian suppliers increasingly favored by carmakers.

Barron'sOil Prices Are Heading Toward $20 a Barrel

Oil prices, which skidded to a six-and-a-half-year low of $41.35 a barrel last week, could fall to $20 as professional speculators sell. That’s the prediction of Steve Briese, editor of the Bullish Review of Commodity Insiders, and a key source for Barron’s prescient March 31, 2014 cover story, “Here Comes $75 Oil.” A $20 capitulation low could lead to a rebound, he says.

With West Texas Intermediate, the U.S. benchmark crude, trading at $100 a barrel in March 2014, our cover story struck many readers as too bearish by half. It turned out to be too modest by half. Investors can use exchange-traded funds such as the United States Oil fund to invest in oil futures; ETFs such as the Energy Select Sector SPDR (XLE) target energy stocks. Both funds may have further to fall.
