Oppenheimer analyst Colin Rusch raised his price target for Tesla (TSLA) to $612 from $385 and keeps an Outperform rating on the name. The stock closed Friday down $3.19 to $478.15. 

While Tesla "has stumbled through growing pains," the company has reached "critical scale" sufficient to support sustainable positive free cash flow, Rusch tells investors in a research note titled "What to Do Now with TSLA Shares?" Further, the analyst believes the company's "risk tolerance, ability to implement learnings from past errors, and larger ambition than peers are beginning to pose an existential threat to transportation companies that are unable or unwilling to innovate at a faster pace."

Tesla has key advantages in powertrain design, battery technology, advanced driver-assistance systems fleet size, roadmap to energy independence offerings, and consumer enthusiasm that can translate into material operating leverage, share gains, and market disruption as renewables and autonomy trends accelerate, contends Rusch.
