Tesla stock ended Thursday at $180.01, up 2 cents, and didn't get much of a boost from a new bullish call from Cantor Fitzgerald.
Analyst Andres Sheppard launched coverage with a Buy rating and a price target of $230.
Buy ratings typically help any stock, but coming into Thursday's session Tesla shares already were up about 27% from a 52-week closing low of $142.05 reached on April 22, a day before Tesla reported better-than-feared first-quarter earnings.
In premarket trading Friday, Tesla shares were down 0.2% to $179.61, while S&P 500 and Nasdaq Composite futures jumped 0.3% and 0.6%, respectively.
Apple was helping the indexes. The tech giant's shares were rallying 5.7% in premarket trading after the company said it expects sales in its fiscal third quarter to come in at about $83 billion, in line with Wall Street estimates but above what investors feared, wrote Melius Research analyst Ben Reitzes in a report Thursday.
