It does matter how investors value the company.
If you have something and people are willing to pay $10 for it, it is worth $10. No matter how much someone else says it is worth $5.
By the same token it is worth $10 no matter how much someone else says it is worth $20. It is worth what people are willing to pay for it.
It all matters to a point. Everything regarding dollars and cents matters when you are valuing something. That's where we are right now, what is the value of Visteon? Is it 2 billion, 4, 6, 8..... Judge Sontchi believes he is the best person to decide. I think he is wrong. I believe the best person (company) to decide would be an independent third party who has proven expert knowledge of valuing companies, especially automotive companies.
