The Federal Reserve takes center stage in the coming days with the first estimate on third quarter GDP due out Friday and the central bank's November statement out next Wednesday. "The Q3 GDP report is absolutely vital," said Lindsey Piegza, chief economist at Stifel Fixed Income. "The first half of the year was extremely disappointing with an average growth rate of just 1%." Wall Street expects third quarter GDP to rise 2.5%, compared to the 1.4% growth seen in second quarter. She said a higher-than-expected GDP print could give the Fed the green light to raise interest rates by the end of the year, though she doesn't think a rate increase is warranted until 2017, amid lackluster economic data.
