The benchmark S&P/ASX200 index on Thursday rose 16.5 points, or 0.21 per cent, to 8,027, while the broader All Ordinaries gained 24.1 points, or 0.29 per cent, to 8,258.1.

All of the gains this week have been small, less than a quarter of a percentage point. But IG analyst Tony Sycamore said the gritty grind higher might be more sustainable than an explosive rally built on shaky foundations.
Thursday's gains seemed to be driven by the overnight release of minutes from the US Federal Open Market Committee's last meeting making it clear it was all but certain the Fed would cut US interest rates in September.
