LONDON (MarketWatch) -- European stocks slipped Monday, extending a run of declines stemming from concerns about stagnant growth in the eurozone.

The Stoxx Europe 600 index ended down 0.1% at 321.56 after spending much of the session in higher territory. The intraday gains for the index were driven by technicals "rather than fundamentals," said Christian Tegllund Blaabjerg, senior strategist at Danske Bank Markets, in emailed comments.

The Stoxx 600 last week fell 4.1%, the worst weekly decline since May 2012. It came largely as dreary data from Germany fueled concerns about a possible contraction in Europe's biggest economy.

It's the "threat of the eurozone plunging into recession for the third time that's really knocked sentiment," said Joao Monteiro, analyst at Valutrades, in a note on Monday. "[U]ntil we see something that serves to convince the market otherwise, then the shakeout may well continue."

The release of corporate financial results will pick up pace in Europe as well as in the U.S. in the coming days. Earnings for European companies are expected to grow 7%, said Tegllund Blaabjerg, "which will not be beaten in my view."

Aggregated third-quarter revenue for Stoxx 600 companies is poised to pull back by 0.8% from the year-earlier period, according to figures released Friday by Thomson Reuters. Just four of 10 sectors are expected to post higher sales, with utilities set to log the lowest rate of growth.

Market action: Downgrades in the chip sector weighed on the Stoxx 600. Infineon Technologies AG lost 2.1% after its rating was cut to neutral from overweight at J.P. Morgan Cazenove, which cited weakening demand both in Europe and China. STMicroelectronics NV was also cut to neutral from overweight, and its shares dropped 4.6%.

Luxottica Group SpA sat at the bottom of the Stoxx 600, losing 9% after Chief Executive Enrico Cavatorta resigned roughly two months after he took the reins at the eyewear maker.

But topping the Stoxx 600 was Anglo-American PLC , gaining 4.7% following an upgrade of the iron ore miner to outperform from neutral at Credit Suisse.

In France, the CAC 40 rose 0.1% to 4,078.70, and Germany's DAX 40 gained 0.3% to 8,812.43. The FTSE 100 index ended 0.4% higher at 6,366.24.
