Tesla is burning through cash — and it could become a problem (TSLA, GM)

Tesla spent $1 billion in the third quarter.
General Motors also spent $1 billion in the quarter.

Of course, nobody expected a good quarter, and in October the carmaker's stock had already slid significantly from its 2017 peak of almost $400 a share.
