Tesla Motors Inc (NASDAQ:TSLA) jumped 2.57% in pre-market trading after the electric auto-maker received an Outperform rating and by Oppenheimer analyst Colin Rusch this morning. Rusch provided a $340 price target, marking a 38% potential upside from current levels. The analyst noted, “We continue to believe that a successful launch and ramp of the Model X are largely priced into TSLA shares but that a ramp of the gigafactory, proving the market for stationary storage, and the Model 3 are still not reflected in the current price.” He notes several near-term catalysts such the launch of stationary storage products in the fourth quarter, and also points to the timely ramp of the Gigafactory. Tesla unveiled its Model X yesterday, expanding the company’s product offerings with the compact SUV.
