On the economic front, the Commerce Department released a report showing new home sales rose 4.7 percent to an annual rate of 337,000 in February from an upwardly revised January rate of 322,000. The results surprised economists, who had been expecting sales to fall to 300,000 from the 309,000 originally reported for the previous month.

Additionally, industry data released earlier showed that mortgage application volume rose over 32 percent last week, as low mortgage rates on the heels of the Fed's decision to buy Treasury securities encouraged both the purchase and refinancing of mortgages.

Earlier in the day, the Commerce Department released a report revealing durable goods orders jumped 3.4 percent in February after falling by a revised 7.3 percent in January. Economists had been expecting durable goods orders to fall by 2.5 percent compared to the 4.5 percent decrease that had been reported for the previous month.
