General Motors will raise its spending on electric and autonomous vehicles and add two U.S. battery factories as it gambles that consumers will eagerly switch from gasoline to the new technology. The announcements Wednesday came as crosstown rival Ford said its entire Lincoln luxury brand lineup would be electric or gas-electric hybrid by 2030, including four fully electric vehicles. For months, the automakers have been one-upping each other with electric vehicle announcements, which have fueled stock price increases for both companies. GM wouldn't give details about where it will build the new plants, but Chief Financial Officer Paul Jacobson said they would be similar in size to two factories now under construction in Lordstown, Ohio, and Spring Hill, Tennessee. Those factories each will employ more than 1,000 workers and cost about $2.3 billion.

President Donald Trump's tweets have caused headaches for everyone from Mexico's currency traders to the world's most valuable companies. Now there's a robot out to profit from the pain. Meet the Trump and Dump bot, a computer program that automatically shorts stocks based on Trump's tweets. Created by the advertising agency T3, the software extracts companies named in the president's tweets and analyzes their sentiment. If the tweet is deemed negative, the bot will short the stock within seconds and then send an alert to T3. "What do you do when Trump is tweeting about these companies and their stocks are going down?" said Ben Gaddis, president of T3.
