The benchmark S&P/ASX200 jumped 77.5 points on Thursday, up 0.86 per cent, to 9,068.4, as the broader All Ordinaries surged 76.9 points, or 0.83 per cent, to 9,375.9.

After weeks of low volatility, a shock uptick in September unemployment lit a match under expectations of an interest rate cut.
While many major bank economists expect the Reserve Bank to hold the cash rate at 3.6 per cent in November, rates markets indicate a cut is 80 per cent likely and have fully priced a rate reduction by the end of the year.
"This time yesterday, markets were tossing up whether the first cut would be in the first quarter of next year or the second, so that's that's a pretty significant move," Capital.com market analyst Kyle Rodda told AAP.
"It's given stocks a bit of a boost and that's why we've got those rate-sensitive areas of the market like banks and real estate stocks leading the charge."
