Tesla said on Wednesday that it would build a factory in Mexico to manufacture an electric vehicle that would be significantly more affordable than any of the cars it sells now. But the company disappointed investors who were expecting the company to make big announcements about new products and strategies.

Shareholders and analysts had expected Tesla to reveal information that would clarify how the company would retain its crown as the world’s dominant maker of electric vehicles in the face of energetic competition from established carmakers and relatively younger Chinese manufacturers.

Instead, company executives offered a seminar on its manufacturing processes, supply chain organization and software. The message was that Tesla is eons ahead of other automakers in technology and efficiency, on track to someday produce 20 million vehicles a year, twice as many as Toyota does now. Tesla provided few of the financial bullet points or strategic initiatives that are often found in investor presentations.
