Tesla Inc.’s shares rose 14% Tuesday to $887.06. They have surged 56% in the past week and have nearly quadrupled since early October. Those outsize gains don’t match Tesla’s more modest fundamentals, which include annual losses. They do, however, resemble any number of other assets that have experienced prolonged bubbles, including shares of Qualcomm Inc. and other tech stocks of the dot-com era; oil in 2008; and bitcoin in 2017.
