I tried to do some searching...Google. I saw this one...2009 https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjPn_ypg6v3AhV5D0QIHcRXAWwQFnoECCIQAQ&url=https://www.theguardian.com/business/2009/jan/27/profit-struggling-firms&usg=AOvVaw1LYZVKZLMx1fhQ0nSKUUvV It seems that hedge funds go after known assets. They might shy away from concepts and patents that are not proven. They will fund (small percent of the company), but not go deeper down a rabbit hole (good money after bad). I learned a new word today...Vulture Funds!! A vulture fund is a hedge fund, private-equity fund or distressed debt fund, that invests in debt considered to be very weak or in default, known as distressed securities.[2] Investors in the fund profit by buying debt at a discounted price on a secondary market and then using numerous methods to subsequently sell the debt for a larger amount than the purchasing price. Debtors include companies, countries, and individuals.
