Tesla stock ( NASDAQ:TSLA ) has experienced a roller coaster of a month this June, at one point almost coming within reach of its all-time high before plunging back 6.9% last week and settling at $333.63. As of June 22, Tesla had risen 25.4% quarter-to-date, making it one of the best-performing stock among automakers. Since then, however, the company's shares have plunged ~10% amid reservations about the viability of the Model 3's fourth assembly line and an ongoing lawsuit against a former employee.
