If it's any consolation, 2008/9 proved that everything is pretty much correlated--stocks went down, bonds went down, everything went down. There were no safe havens except for massive government bailouts. To this day, the illegal acts that banks undertook to stay afloat have not been prosecuted (moving all unperforming assets to "off balance sheet vehicles" like holding companies). Also, mark-to-market accounting was suspended and has never been reinstated.
