US STOCKS SNAPSHOT-Futures hold on to gains after December PCE data

Jan 31 (Reuters) - U.S. stock index futures held on to their gains on Friday, as an in-line inflation reading did little to alter market expectations about the Federal Reserve's interest-rate path.

The personal consumption expenditures price index rose 0.3% in December, compared to a 0.3% increase forecast by economists polled by Reuters. In the 12 months through December, PCE inflation advanced 2.6% against an expectation of 2.6%.

Excluding the volatile food and energy components, the PCE price index increased 0.2% last month against expectations of a 0.2% increase. Annually, it came in at 2.8%, compared with a forecast of 2.8%.

At 08:32 a.m. ET, Dow E-minis 1YMcv1 were up 125 points, or 0.28%, S&P 500 E-minis EScv1 were up 26.25 points, or 0.43% and Nasdaq 100 E-minis NQcv1 were up 155 points, or 0.72%.
