Great question and I have asked myself this without a definitive answer. I believe there are three types of investors of TSLA stock , First, the 'I believe in the EV revolution and Elon and am here long term (10+ years) no matter what. Second, ' My intent is to be a long holder (5+ years) until the Gen III (E) vehicle shows that Tesla can make an affordable, compelling, long range (200+) mile EV and the company/stock are mature so that the possibility for the big run ups (gains) are not there anymore and I will move to another high tech/growth company'. Finally, 'I intend to buy and hold but with the swings sometimes I 'day trade/week trade/trade near earnings calls'.
