On CAPS, 53% of the 693 members who have rated Tesla believe the stock will underperform the S&P 500 going forward. These bears include NEALWF and fellow Fool Seth Jayson (TMFBent), who is ranked in the top 0.5% of our community.

Just last week, NEALWF nicely summed up the Tesla bear case:

Major manufacturers on the verge of mass producing electric cars, what is their differentiation? The only shot at identity was their "sports" coupe (how most automotive brands build a name) but they just announced they are discontinuing it? death sentence imo.

Currently, Tesla even trades at a particularly lofty price-to-sales ratio of 21. That represents a massive premium to other auto plays like GM (0.3), Ford (0.4), and Toyota (0.6).

Just last week, Seth offered a rather biting critique of Tesla:

[L]et's see, only went public with the aid of taxpayer money and to give Musk some cash to pursue his playboy lifestyle ... No longer producing the only thing that got the company any interest (the roadster). Entering the market for a sedan that no one really wants, with technology anyone can have. Gone in 5 years.
