Outlook for the day: Positive after Wall Street welcomes a record quarter from Nvidia and a decline in bond yields.

ASX futures: up 36 points or 0.51%

Overnight themes:
Wall Street has its best day in almost two months ahead of earnings this morning from tech heavyweight Nvidia.
The S&P 500 gains more than 1% for the first time in 37 sessions. The Nasdaq rises for a third session as Nvidia rallies 3.17%. The chipmaker has been this year's best performer, advancing more than 220% on optimism about the outlook for artificial intelligence.
Nvidia soars almost 10% in after-hours trade to an all-time high after reporting a record quarter in which revenues doubled.
"Not just their numbers, but what they say in the conference call about what's happening in AI is going to have a big impact on market sentiment" - Rick Meckler, partner at Cherry Lane Investments.
Treasury yields back off 16-year highs following signs of weakness in US business activity. The 10-year yield drops more than 11 points to 4.21%.
August data shows the US services sector growing at its slowest in six months. Manufacturing continues to contract. Payrolls data is revised downwards, implying the labour market has not been as strong as previously believed. Eurozone activity also contracts more than expected.
Ten of eleven US sectors rise, led by tech (+1.92%), communication services (+1.9%) and real estate (+1.46%). Energy is the only loser, easing 0.3% as crude continues its recent weakness.
Iron ore rises for a 10th session in China as inventories decline and Beijing ramps up support for the economy.
"Iron ore supply and demand continue to be tight, and the inventory at various links is at a low level" - Huatai Futures analysts.
Gold has its best session of the month, lifting for a fourth session. Gold for December delivery gains almost 1.2%.
