Question 1: When will a new GM stock be available after backruptcy?
No one knows for sure, it depends on the time line for the company structure, what there internal metrics would be for achieving the goals necessary before going public again and it must be approved by its current debt and equity holders (the unions and US/Canadian governments). If I had to venture a guess 24-36 months before they went public again.
Question 2: How much will it open at?
This won't be determined until the decision to go public is made and approved, at that time the investment banks handling the offering will determine what the fair value of the firm is and what the demand for the IPO would be, they will then determine how much to issue the shares at.
