Wall St edges higher as S&P 500 tops record close

US stocks edged higher on Thursday, with the S&P 500 rising just above its record closing high, which has acted as a significant resistance point in recent weeks.

The S&P had been caught in a range, having traded within 10 points of the record closing high of 1,565.15 over the prior 13 sessions before successfully piercing that level on Thursday, while buyers moved in on signs of weakness to quickly eliminate any declines.
