The ASX 200 climbed to decade long highs, despite a global pull-back in risk appetite last week to close trading around the 6225-mark. A recovery in bank shares drove the run higher, with the Big 4 banks regaining ground after several weeks of aggressive selling – and in doing so, dragging the rest of the index with it. Consumer stocks also got a boost during the week, after Parliament successfully passed the Turnbull Government’s tax-cut package on Thursday. The developments underpin strong foundations to start the new week, with SPI futures indicating a higher open for the ASX, largely thanks to expected gains to materials stocks following a rally in oil prices post Friday’s OPEC+ meeting. The question now is: how far can this run go? Perhaps an answer could lie in the chart below, which reveals the development of a potential topside trendline for the index.
