ASX set to slide; Aussie back above 72 US cents

Summary

• SPI futures are down 5 points, or 0.1%, and hint at a weak start for the benchmark ASX200 
• A spending-heavy federal budget - and the prospect of more US stimulus - helped the local bourse cap its best week in six months with a fifth straight rise on Friday
• US stocks also ended the week higher, with both the S&P 500 and NASDAQ recording their best week since July, as optimism grew over fiscal aid
• The Aussie dollar was worth US72.28c at 8.30am AEDT and over the weekend climbed to a near three-week high of US72.42c
