Wells Fargo maintains 'Underweight' rating on Tesla, citing no stock rebound soon.
Tesla's vehicle deliveries are expected to decline in Europe, China, and the US.
Earnings may drop 25% by 2025 due to lower deliveries and lower profit margins because of price cuts.
Wells Fargo analyst sees concerns over vehicle deliveries, earnings decline, lack of details on a low-cost model, skepticism towards the autonomous driving technology, and unattractive valuation for Tesla stock.
