Tesla Stock Falls After Big Gains as Auto Industry Wrestles With Copper Prices

Tesla stock was a little lower early Tuesday after an epic Monday, as the car industry looks for solutions to rising commodity prices. Tesla stock gained 8.5% on Monday, rising roughly $30 a share, more than wiping out $20-per-share losses of the prior week. Tuesday’s early move came as Reuters reported that several auto makers were using some aluminum wiring instead of copper.
