Nine sectors hold gains in afternoon trade with the consumer discretionary sector (+1.2%) defending the lead. This has narrowed the group's week-to-date loss to 0.4% while top-weighted technology (+1.0%) is on track to gain 1.3% for the week.
On the downside, health care (-0.3%) underperforms today, continuing this week's show of relative weakness that has the sector down 3.0% since last Friday, largely due to underperformance among biotech names.
