Tesla is never just about the numbers, at least that's what Wedbush Securities analyst Craig Irwin believes. While people have high hopes for the upcoming earnings and expect $824 million in sales, Irwin thinks the second quarter is already in rear view mirror. He is keeping an eye on Tesla's popularity in China, the world's largest luxury car market. He said, "China remains the most significant driver of potential upside. We hear Tesla’s traction is impressive." With chatters about Gigafactory emerging, Irwin believes that Texas, California and Nevada are likely choices for the location. The success of future cars will largely depend on whether Tesla can manufacture cheaper batteries.
