(Sharecast News) - European stocks were rangebound on Tuesday as equity markets continued to pause for breath following the recent rally, which saw the Stoxx 600 rise more than 6% over the past three weeks.

After pushing higher in morning trade, the Stoxx 600 was trading more or less flat at 517.91 by lunchtime, with most indices across the continent registering moderate gains of no more than 0.3%. The pan-European benchmark has risen in 12 of the last 15 trading sessions since hitting a six-month low on 5 August.

"This week is likely to be dominated by Nvidia results and a second estimate of US second-quarter GDP," said AJ Bell investment director Russ Mould.

Likely keeping a lid on risk appetite was a deteriorating outlook for the German economy, as confirmed by a consumer survey released by GfK and the Nuremberg Institute for Market Decisions on Tuesday.

The forward-looking consumer sentiment index for September fell to -22 from a revised -18.6 in August, coming in below expectations for a reading of -18.2. Rolf Buerkl, consumer expert at NIM, said that slightly rising unemployment rates, an increase in corporate insolvencies and staff reduction plans at various companies in Germany are causing employees to worry about their jobs.

Meanwhile, the final reading of second-quarter German GDP was revised higher, with the year-on-year change improving to 0% from -0.1% in the second quarter, better than the flash reading of -0.1% released last month. Quarter-on-quarter growth however remained at -0.1%, after the economy expanded by 0.2% in the first three months of the year.
