Tesla (TSLA) has been one of the hottest stocks of 2020, with share prices skyrocketing 582% just this year. But at least one analyst says the electric vehicle company’s price is too high, contending it should be worth between $60 to $80 rather than more than $600 a share.

Gordon Johnson, founder and CEO of GLJ Research, told Yahoo Finance Live on Monday that Tesla’s lofty valuation will soon come crashing down, with a number of factors weighing on the company’s stock price.

Those include Tesla’s upcoming addition to the S&P 500, set for Dec. 21, which Johnson says could see shareholders who were putting money into the stock ahead of the anticipated event, pulling back, and the loss of government-backed EV (electric vehicle) credits from rival automakers.

Johnson believes Tesla’s stock should be viewed as akin to the likes of over-hyped stocks like cannabis company Tilray (TLRY), which saw a massive run up to nearly $150 a share in late 2018 only to fall back to $7.37 a share. He also puts Tesla in the same ranks as renewable energy company SunEdison, which filed for bankruptcy in 2016 after seeing its stock price rise higher than $32 a share only to drop 99% in 12 months.

“You’ve seen this before. I know it sounds crazy, look at Tilray, look at SunEdison, look at Suntech, some of these stocks, they went from $5 to $300 dollars, back to $5. They went from $2 to $300 back to zero,” Johnson said. “It does happen, and we think that Tesla is a prime candidate.”

Tesla’s stock is notoriously as polarizing as its CEO, Elon Musk. In November 2018, Musk told “Axios on HBO” that the company had been “single-digit weeks” away from death during the ramp-up in Model 3 production. Prior to that interview, in August 2018, Musk had tweeted that he was taking Tesla private at $420 a share and that funding was secured, even though it wasn’t. The Securities and Exchange Commission sued Musk over the tweet, and he and Tesla agreed to pay $40 million in penalties.

This year, Musk may have raised some eyebrows again when he decided to idle its Model S and Model X production lines for 18 days from Dec. 24 through Jan. 10. Johnson called the decision “baffling” in light of recent suggestions from Musk that Tesla needed to ramp up production.

“Just a few days ago, Elon Musk put out an email, an internal email that was leaked to the public, that said they were effectively production constrained, they needed to significantly increase production,” Johnson said. “... So I think it’s one of two things: a, being demand is a problem, or b, they need to retool or refurbish the model to make it more attractive.”
