A bright outlook from Home Depot, which lifted its expectations for full-year results, underpinned the mood on Wall Street.
The home improvement giant posted third-quarter results that beat forecasts and provided an optimistic picture for the coming months – for its own future and that of the housing industry in general. Shares gained 3.9%.
"Our third-quarter results were better than we expected and reflected, in part, what we believe is the start of the path toward the healing of the housing market," Home Depot chief executive Officer Frank Blake says in a statement.
The housing market is becoming "an assist to growth, rather than an anchor".

Meanwhile, the handwringing over Greece continued.
Eurozone finance ministers agreed that the beleaguered country facing a crucial repayment this week needs more time to reduce its debt to gross domestic product ratio, suggesting the deadline for lowering it to 120% should be moved to 2022, from 2020.
IMF managing director Christine Lagarde failed to appreciate that call. "Debt sustainability of Greece has to be measured in 2020," she said, according to Bloomberg.
"We clearly have different views. What matters at the end of the day is the sustainability of the Greek debt."
EU finance ministers will not decide until later this month on releasing the next tranche of bailout funds for Greece.
