NEW YORK (TheStreet) -- Stock futures were wavering Tuesday ahead of the start of the new earnings season, and amid a downgrade of global growth estimates from the International Monetary Fund.

Meanwhile Spain's bailout plans remained uncertain.

"The monthly meeting of Eurozone finance ministers ended with little fanfare," said Gareth Berry, foreign-exchange strategist at UBS.

"The markets continue to look to Spain to ask for a bail out, though the Ecofin is not the group to apply that pressure (at least, not in public)," added Paul Donavan, a global economist at UBS. "The German government says Spain does not need a bail out. This might be an instance of the German sense of humor; it is hard to tell."

The International Monetary Fund said in its latest World Economic Outlook, unveiled in Tokyo ahead of meetings this week of global finance chiefs in the city, that the global economy could grow 3.3% in 2012 and 3.6% in 2013, below its prior forecasts of 3.5% this year and 3.9% next year.

"Low growth and uncertainty in advanced economies are affecting emerging market and developing economies through both trade and financial channels, adding to homegrown weaknesses," said IMF Chief Economist Olivier Blanchard.

However, prospects could improve if clouds over the euro area and the U.S. "fiscal cliff" are lifted, the report added.

"Today we posit the question 'What's the worst that can happen?' with respect to the upcoming earnings season. The answer, at least when it comes to a representative sample of 25 large cap names, is 'Meh ... Not too bad,'" noted Nicholas Colas, chief market strategist at ConvergEx Group. "We're all used to looking at earnings expectations based on the average of analysts' EPS estimates, but what if the most bearish analyst is right every time this quarter? Such a scenario would result in an average 10.3% average miss to expectations for our universe of market-leading names. Take out a few stocks where the worst-case-scenario is +15% away from the mean, and the 'real' worst case is an even-smaller average 6.7% miss. The dispersion grows considerably on Q4 expectations, but the 'worst case scenario' here still just 11.6% off consensus. Bottom line -- the 'worst case' isn't all that bad."
