Some say it was also a push for investors frustrated by the low-yielding returns in ultra-safe securities like CDs and money-market funds to stick their necks out a little farther and put their money in something with a bit more risk. Fed Chairman Ben Bernanke is hoping that investors moving some money around will get the economy moving, too.
