BANGKOK -- World stock markets fell Friday as disappointing U.S. corporate earnings provided a reason to book profits on recent gains while investors waited for a progress report from European leaders concluding a summit on the region's debt crisis.
Britain's FTSE 100 lost 0.1 percent to 5,910.04 in early trading. Germany's DAX was 0.4 percent lower to 7,411.65 and France's CAC-40 lost 0.3 percent at 3,523.74.
"It is one of those situations where we've had such a big run this week, we are at a stage where investors would be nervous to add onto positions or get fresh entries," said Stan Shamu, market strategist at IG Markets in Melbourne, Australia.
Wall Street also looked set to retreat. Dow Jones industrial futures fell 0.1 percent to 13,474 and S&P 500 futures lost 0.1 percent to 1,449.70.
Worse-than-expected U.S. earnings on Thursday were a negative for markets. Microsoft said net income fell a worse-than-expected 22 percent to $4.47 billion in the fiscal first quarter, which ended Sept. 30. Microsoft shares fell in after-hours trading.
BB&T bank, Philip Morris International and Boston Scientific also reported results that fell short of forecasts.
Shares of Internet search trailblazer Google were pummeled after third quarter earnings were released three hours too early by mistake. The results alarmed investors because the company's earnings and revenue fell well below analyst projections. Google's stock price dropped 8 percent, causing $20 billion in shareholder wealth to evaporate.
General Electric, McDonald's Corp. and Schlumberger Ltd. will report quarterly financial results later Friday.
Investors are also looking for more progress from a European summit convened to hash out solutions to the region's debt crisis.
European Union leaders took a crucial step on the opening day of a meeting in Brussels on Thursday by agreeing to create a banking supervisor to oversee institutions in the 17 countries using the euro. The summit concludes Friday.
Asian stock markets plodded through a mostly mixed session.
Japan's Nikkei 225 index rose 0.2 percent to finish at 9,002.68. South Korea's Kospi lost 0.8 percent to 1,943.84. Australia's S&P/ASX 200 rose 0.3 percent to 4,571.10. Hong Kong's Hang Seng added 0.2 percent to 21,551.76.
In mainland China, the Shanghai Composite Index fell 0.2 percent to 2,128.30 and the smaller Shenzhen Composite Index shed 0.2 percent to 877.29. Markets in Singapore, Taiwan, Thailand, Indonesia and India also fell.
