Stock futures were rising Thursday, with investors reluctant to make any big moves ahead of key inflation data that could be the last remaining obstacle to a Federal Reserve interest-rate cut. The moves higher came as investors waited for the August consumer price index report, due at 8.30 a.m. Eastern time. Economists polled by The Wall Street Journal expect the data to show inflation rose 2.9% last month, up from 2.7% in July.
