Australian Resources, Banks and Technology Sectors

On most Australian trading days, three sector stories do most of the work. Resources reacts to overnight commodity moves and Chinese demand signals. Banks reacts to rate expectations, credit conditions and property. Technology reacts to whatever happened in the US session, especially in the NASDAQ.

Resources — iron ore, gold, energy — is the sector where the ASX earns its reputation as a commodity-linked market. Big moves in BHP, Rio Tinto, Fortescue or Woodside can move the whole index. Watching commodities and the AUD in tandem usually tells you more than watching the sector in isolation.

Banks are the other pillar. Australia's major banks dominate the financials sector and are highly sensitive to expectations about interest rates, mortgage arrears, deposit competition and dividend policy. A move in bank stocks often reflects a change in the story about the Australian consumer as much as anything specific to the banks themselves.

Technology is smaller in weight but larger in daily narrative. Australian tech tends to follow the NASDAQ closely, so an overnight sell-off in US technology usually shows up locally by mid-morning. This is where the 'overnight' story most obviously spills into the Australian trading day.

Reading the ASX through these three lenses — resources, banks, technology — is not a substitute for looking at individual names, but it is a fast way to see whether today is being driven by commodities, by rates, or by what happened overseas. FinAI's sector scanner is built around exactly this way of looking at the market.
