Tesla shares have soared this week, eclipsing $900 on Monday and clearing $1,000 during Wednesday's session. The gains are due in large part to positive trends from China, where the company sold about three times as many Model 3's in May as they did in April. Additionally, Tesla's "Battery Day" is expected to be held this month, where we could learn more about Elon Musk's plans for a battery that lasts one million miles. Dan Ives, Managing Director of Equity Research at Wedbush Securities, breaks down why he is excited about Tesla's recent developments.
