Existing home sales will be the first economic indicator of the week, coming from the National Association of Realtors at 10 a.m. Eastern on Monday. Economists expect existing home sales fell 2.5% to 3.47 million units in October. Existing home sales have moved in a narrow range over the past year, in part because of sales of foreclosed homes. New home sales are expected to fall 4.8% to 411,000 units. But some analysts expect a bigger drop to lows not seen since 1982.
