Even though Blackrock appears to be holding onto its position in Tesla Motors for the time being, it does not mean that smart investors should not question Tesla’s future. Recently the Wall Street Journal also reported Elon Musk used the Twitter social platform to declare Tesla on the cusp of positive cash flow. Musk’s interests in Twitter aside, it was a bold statement. Tesla used $233.1 million in cash to support operations over the twelve months ending September 2012. For clarity, that is $19.4 million per month on average. Musk’s declaration might suggest that the situation is improving.
