As with its many comic book heroes, Marvel now appears to be entering a period where it will be tested repeatedly, and the company will likely have to squeeze pennies to make investors happy. Yet there's reason to be hopeful. In a post to our Marvel discussion board Fool contributor Rich Smith points out that Marvel's stock may be vastly undervalued on a cash flow basis."
