NEW YORK ( TheStreet) -- Stock futures were dipping Tuesday as investors awaited the unofficial kickoff of earnings season Tuesday with a report from aluminum giant Alcoa ( AA). Futures for the Dow Jones Industrial Average were off 13 points, or 20.29 points below fair value, at 13,294. Futures for the S&P 500 were down 1.5 points, or 1.94 points below fair value, at 1454.

Aluminum giant Alcoa is expected by analysts Tuesday to post fourth-quarter earnings of 6 cents a share on revenue of $5.61 billion. Shares of Alcoa were up 0.77% in premarket trading. "Starting Tuesday afternoon, with Alcoa's Q4 earnings report, corporate fundamentals will start to matter again -- if only briefly," said Nicholas Colas, chief market strategist at ConvergEx. "U.S. companies have proven time and again over the last four years that they can deliver strong bottom-line results in spite of a tepid global economy. The market-moving information will, instead, be at the top of the income statement -- as it was during Q3 2012 season." Colas' monthly review of analysts' revenue estimates for the companies of the Dow shows an expected rebound from the third quarter's negative 2% year-on-year change to positive 1.1%. On the downside, said Colas, that's what analysts thought last quarter, right before many large multinational corporations missed on the top line. Thomson Reuters is expecting fourth-quarter earnings to grow 2.8% over the same period last year. Thomson Reuters said that of the 21 companies in the S&P 500 that have reported earnings to date for the fourth quarter 2012, 62% have reported earnings above analysts' expectations. This matches the long-term average of 62% and is lower than the average over the past four quarters of 65%.
