Tesla is set to unveil its long-awaited robotaxi on Thursday, but some analysts remain skeptical. Meanwhile, Elon Musk’s company has once again become the most shorted stock in the U.S.

According to Hazeltree, Tesla returned to its position as the most crowded shorted large-cap stock in America in September. At the same time, Wells Fargo included the company’s stock in its trading ideas with an “underweight” recommendation, expressing doubts about the success of the robotaxi.

Since April, when Musk announced plans for the robotaxi, Tesla stock has risen by more than 40%, even despite delays in the event. Wells Fargo analyst Colin Langan set a price target of $120, which is half of its current price, citing slowing delivery growth and reduced demand for EVs.

Tesla announced that its third-quarter results will be released on October 23.
