Earnings at U.S. automakers are expected to decline in the next two years as negative pricing and lower production weigh on North America results, Goldman Sachs said, downgrading the sector to "cautious" from "neutral".
Major automakers posted September U.S. sales that were slightly lower than a year ago, despite big consumer discounts, as pickup truck volumes fell for both General Motors Co and Ford Motor Co .
"The US auto cycle peaked in 2015 and is currently being held at a plateaued level by increasing OEM incentives," analysts David Tamberrino and Mariel Kennedy wrote in a note.
The analysts said they expected seasonally adjusted annualized rate (SAAR) to hold steady from current levels into next year, followed by a gradual decline.
The brokerage downgraded Tesla Motors Inc to "neutral" from "buy" and cut its price target to $185 from $240.
The analysts said any delay in the timeline for the launch of the electric carmaker's much-hyped Model 3 would hurt shares. They also cited Tesla's deal to buy SolarCity Corp as a concern.
"Combination of Tesla and SolarCity ��� two high growth, high cash burn businesses, creates a higher risk entity," the analysts wrote.
Tesla's shares were down 2.65 percent at $202.93 in premarket trading on Thursday.
The analysts were neutral on Detroit carmakers Ford and GM, saying dividend yields are a cushion and not at risk over the next 12 months.
Shares of both companies were untraded premarket.
The brokerage downgraded auto part suppliers Lear Corp and BorgWarner Inc . Lear's rating was cut to "sell" from "neutral", while BorgWarner was downgraded to "neutral" from "buy".
However, the brokerage said suppliers who had more international profit exposure could see earnings hold up longer, maintaining a "buy" rating on Lear's rival Delphi Automotive Plc .
