Now for a look at the European economy. The European Central Bank at a meeting on Thursday left key interest rates unchanged.
The ECB also announced that it was cutting back on its monthly purchases of euro zone bonds. The bank said it would cut its bond buys in half to 30 billion euros a month beginning in January. At the same time, the ECB extended the bond-buying program's lifespan to nine months. Analysts say that's the ECB's biggest step yet in weaning the euro zone economy off years of stimulus.
