Credit Suisse on Thursday noted that Tesla has nearly an 80% share of the U.S. market for electric vehicles but the firm expects that the automaker's "unique position" with its Model 3 will face a serious challenge from Ford next year.

"For all the competition entering the market we are still awaiting the EV that will be a true competitive threat to Model 3 – especially in the US," Credit Suisse analyst Dan Levy wrote in a note to investors. "Tesla has a window of opportunity now with a clear competitive lead."

While a statement like this may be common among Wall Street's bullish Tesla analysts, Credit Suisse remains one of the company's skeptics. Credit Suisse has had an underweight rating on Tesla shares since the firm began covering the stock in June, with a $200 price target. That's more than 40% below the stock's close on Wednesday at $346.11 a share.
