Peter Cardillo, chief market economist at Rockwell Global Capital, discusses the Federal Reserve's decision not to taper the central bank's $85 billion-a-month bond-buying program and what "significant improvement" in economic data Fed Chairman Ben Bernanke and policy-makers are looking for. In addition, Cardillo weighs in on what to watch for on next week's economic calendar, including durable goods orders, housing data such as the FHFA Housing Price Index, new home sales and pending home sales, as well as personal income and consumer spending.
