Consuelo Mack, the host of the PBS show "Consuelo Mack WealthTrack" makes a pretty strong case for charging into the market now, while likening it to a shoe sale (the bold is mine):
"When a place like Macy's has a shoe sale, you want to be a buyer at that time. This current market situation is like that Macy's shoe sale: It's the stock-sale of a generation. So keep doing your dividend reinvestment programs, keep on dollar-cost averaging, and keep investing in increments. Two to three years from now, you'll be glad you did or wished you had."
