Wall Street expects another bumpy day for stocks should Wednesday’s US inflation number miss in either direction.
Forecasters expect the report to show a fifth month of firm increases, with the core consumer price index seen rising 0.3% in December, according to a Bloomberg survey. A number above that level will see stocks fall about 1% to 2%, while a softer result could spark a rally of similar magnitude, according to JPMorgan Chase & Co. and Goldman Sachs Group Inc.
