Stocks fall after biggest weekly loss since 2012
Falling oil prices pushed US stocks down broadly on Monday, extending losses into a second week.
European stocks also fell, and the Russian ruble plunged to a record low against the dollar as the continuing collapse in the price of oil reverberated through global financial markets.
A brief rally after trading opened in the US vanished as crude oil continued a six-month slide that has slashed its price nearly in half. Global demand for oil has been waning just as supplies are becoming more abundant.
The stock losses in the US were modest, but markets in Germany and France fell more than 2 percent. The Russian ruble plunged, sending stocks sharply lower there, too.
