TheStreet's David Peltier and Andrew Krill preview the week ahead with a focus on fourth quarter earnings, FOMC minutes and the December jobs report. Alcoa is set to kick off earnings season on Thursday and Q4 earnings from S&P 500 companies are expected to grow 5.2%. On Wednesday, the release of the FOMC minutes could spark volatility if there is more talk of tapering, and on Friday the December jobs report will be released. Expectations are for U.S. employers to have added 193,000 jobs in the final month of the year. Forecasts are for the unemployment rate to be 7%.
