Elon Musk Tempers Expectations Ahead of Tesla Battery Day

Tesla (NASDAQ: TSLA) CEO Elon Musk threw some cold water on investor excitement leading up to the automaker's Tuesday evening battery event, warning the company's new technologies will take time to scale. Tesla shares are up 115% over the past three months in part on growing anticipation about what will be announced at the company's battery event. Investors are hoping that new, improved batteries and manufacturing processes can give Tesla a competitive advantage against a slew of new electric vehicle competition from traditional automakers and start-ups.
