Is it possible that his numbers are plain wrong?
At least the CNBC interview, unless I'm misunderstanding something, gives a very wrong impression:
He suggest that with Audi's revenue, and Porsche's margins (which he says are among the highest in the industry), you would get to a market cap of $8 to $10 billion. (The $67.12 share price number seems to be based on $8 billion).
However, according to this:
Audi AG (NSUG.DE) Quote| Reuters.com ,
Audi's market cap is $35 billion, and I'd understand him as implying that with Porsche's margins, it would be even higher, let's say (at least) $40 billion.
That would correspond to a share price of more than $320. According to his logic, or not?
