Tesla is a good company, but has cash flow/debt risk and is it has a higher market cap than GM.
Huh? Tesla has the highest cash reserves they've ever had, and were cash flow positive by nearly $600M for 2Q, and around $850M for both 3Q and 4Q of last year. For the trailing 4 quarters they're way cash flow positive. For 2018 they weren't cash flow positive, but it wasn't much of a miss.
1Q2019 was about -$950M in cash flow. 1Q is typically bad for all car manufacturers.
It would be difficult for Tesla to not be cash flow positive for 2019 overall.
