Tesla shares closed the day about 3 percent higher, around $274. Skepticism has often surrounded the money-losing company's stock price.
Kallo has a $335 price target on Tesla shares. He believes the Model S upgrades, as well as Musk's saying deliveries of the upcoming Model X and Model 3 vehicles are on schedule, will help move the needle.
He called the Model X, which is slated to reach consumers later this year, "the next major catalyst" for Tesla.
