Dodona I, LLC, invested $4 million in two securities offerings from Goldman, Sachs & Co. The investments were in collateralized debt obligations (CDOs). Their value depended on residential mort- gage-backed securities (RMBSs), whose value in turn depended on the performance of subprime residential mortgages. Before marketing the CDOs, Goldman had noticed several red flags relating to investments in the subprime market, in which it had invested heavily. To limit its risk, Goldman began betting against subprime mortgages, RMBSs, and CDOs, including the CDOs it had sold to Dodona. In an internal e-mail, one Goldman official commented that the company had managed to make some lemonade from some big old lemons. Nevertheless, Goldmans marketing materials provided only boiler- plate statements about the risks of investing in the securities. The CDOs were later downgraded to junk status, and Dodona suffered a major loss while Goldman profited. Assuming that Goldman did not affirmatively misrepresent any facts about the CDOs, can Dodona still recover under SEC Rule 10b-5? If so, how?i

Can anyone help me with this without any further background information thank you so much!
