When Elon made his comments about the share price, we were in the period between the end of the quarter and the earnings report for that quarter. It should be regarded as a quiet period for comments from company executives regarding matters that could affect the share price. Rightly or wrongly, Elon's somewhat negative responses to questions about the share price may have been interpreted by many to indicate that the upcoming earnings report will be disappointing.
When asked about the stock valuation last week, Elon should simply have said that we are in the quiet period and cannot comment on that. The company really needs marketing, public relations and finance departments that have influence on company executives who are primarily engineers regarding what they should be saying in public.
