Markets fell again on Friday.
The STOXX Europe 600 fell 1.1 percent to 238.88. It was down 5.2 percent for the week.
The S&P 500 fell 0.7 percent to 1,295.22, Facebook's market debut failing to give the overall market a lift. The index fell 4.3 percent for the week.
Commodities managed to edge up though, boosted by gains in wheat and gold. However, oil and copper both fell to multi-month lows.
While the recent weakness in markets has been driven by developments in Europe, there has been a longer-term decline in the prices of homes in China. New home prices in April fell on a year-on-year basis in 46 out of 70 cities in China while 43 cities saw declines in month-on-month terms.
Calculations by Reuters showed that average home prices in China fell 1.2 percent last month from a year earlier and 0.3 percent from the previous month, the seventh consecutive monthly decline.
