The S&P/ASX 200 index was up 0.5%, or 41.70 points, to 8629.90 at 10.10am AEDT, with nine of the 11 sectors in positive territory. For the week, the benchmark is on track to fall 0.8%.

“November’s inflation undershoot has armed Fed doves with strong ammunition for a January rate cut,” Principal Asset Management’s Seema Shah said in a note. “It’s just one month of data, and distortions can’t be ruled out, but the sharp drop in annual inflation leaves the Fed with little excuse not to respond to rising unemployment.”
