Stocks rise after core inflation rises by less than feared in December
SPDR S&P 500 ETF erased premarket losses to jump higher after core CPI inflation rose 0.2% month on month in December, slightly less than analysts had forecast.
Economists anticipated that headline and core CPI inflation (the latter of which strips out food and energy prices) would be up 0.3% month on month. Headline CPI did indeed rise 0.3% for the month.
The pricing of event contracts for December CPI implied that traders expected headline inflation to be up 0.3% month on month, with higher odds of a reading coming in above than below.

The November CPI report showed that core inflation had cooled by much more than expected, with the annual rate decelerating to a 4.5-year low. However, that reading was flattered by the Bureau of Labor Statistics’ decision to assume housing-centric components were flat in October.
Annual core CPI inflation held steady at 2.6% in December, having been projected to tick up to 2.7%.
