Tesla Inc.’s stock extended losses for a fifth straight session on Monday. The stock closed at its lowest level since March 2017, and lost more than $10 billion in market capitalization in one week.
Even as the electric carmaker's sales of Model 3 sedan are performing well in the U.S. and third quarter projections for it look healthy, the company's CEO Elon Musk’s tweets mocking the Securities and Exchange Commission (SEC) by calling it the “Shortseller Enrichment Commission” might have diluted the positives and therefore potentially added to investor concerns.
