The investment trends emerging from ASX reporting season

This reporting season could make 2027 far more interesting than investors expect.

We're still talking about inflation, weak growth, geopolitical risk and whether markets have run too far. Yet beneath those concerns, some of Australia's biggest companies appear to be preparing for something very different.

Look at where the money is flowing. BHP's latest result showed copper overtaking iron ore as its largest earnings contributor. Rio Tinto has delivered $870 million in productivity benefits while increasing its exposure to copper, aluminium and lithium.

Across the sector, investment continues to flow into copper, lithium, rare earths and critical minerals. These aren't decisions made for the next quarter. They're bets on where demand could be years from now. We're also seeing important changes elsewhere.

After a difficult period, CSL expects underlying profit to grow in FY27 despite broadly flat revenue. AGL is forecasting stronger earnings as its battery portfolio expands and costs fall. Then there are interest rates.

The RBA expects inflation to move back towards its target over time. Meanwhile, CBA is forecasting two rate cuts in 2027. If rates fall while companies emerge leaner and more efficient, the combination could be powerful.

So, what would I be doing with this information? I'd watch for companies demonstrating three qualities: falling costs, improving earnings potential and investment in areas where future demand is growing.

Not because 2027 is guaranteed to be a great year. Rather, this reporting season is providing an early look at where corporate Australia is placing its bets.

The headlines remain focused on what could go wrong. Yet some of Australia's biggest companies are spending billions on what they believe will go right.

That is the part of this reporting season I wouldn't ignore.

Best and worst sectors

Healthcare was the best-performing sector this week, rising more than 11%. The gain was driven largely by an impressive result from its biggest constituent, CSL Limited.

Materials gained more than 5%. Investors responded positively as mining giants including BHP and Rio Tinto continued shifting towards higher-growth commodities. This helped offset the effect of weaker iron ore.

Energy also rose more than 3%. Another surge in oil prices supported the sector as instability surrounding the Iran conflict continued.

At the other end of the market, Financials was the weakest sector, falling more than 5%. Selling continued from the previous week as reporting season weighed on sentiment towards the sector.

Consumer Discretionary dropped more than 4%. JB Hi-Fi's result triggered a broader sell-off across retail stocks.

Consumer Staples fell more than 2%. The recent weakness may reflect short-term profit-taking after the sector's strong run earlier this year.

Best and worst stocks

CSL Limited led the ASX Top 100 this week, climbing more than 25% following its FY26 result. The market responded positively to the company's major restructuring plans.

Pro Medicus followed, rising more than 15%. Another strong FY26 result reassured investors that its underlying growth story remains firmly intact. Evolution Mining rounded out the leading performers, gaining more than 14%.

The company delivered a record FY26 result, supported by another strong rise in the gold price.

At the other end, JB Hi-Fi was the weakest performer, falling more than 14%. Despite record FY26 sales, investors focused on weaker recent trading and its implications for FY27 growth.

Aurizon Holdings followed, falling around 13%. Expectations of lower coal earnings in FY27 overshadowed an otherwise solid result. HUB24 also fell more than 12% despite delivering strong earnings growth.

After a significant rise in recent years, its share price is now trading sideways. Investors are now weighing how much future growth is already priced in.

All Ordinaries Index update

The All Ordinaries Index finished almost flat, falling just 0.16% this week. However, the most important move came on Thursday.

After drifting lower earlier in the week, the market tested the 9200 level we've been highlighting.

Buyers then stepped in and pushed the market higher. That initial reaction is encouraging and reinforces 9200 as the key level to watch. If it fails to hold, 9000 becomes the next important support level.

Interestingly, Healthcare was the strongest-performing sector this week, led by CSL. Materials also performed strongly.

That is encouraging given the significant volatility we've seen in individual stocks throughout reporting season.

Only a couple of weeks of reporting season remain, and most major companies have now released their results. We should therefore see volatility begin to settle.

This should also provide a clearer picture of where the market wants to head next. The market's underlying structure looks considerably different from what we saw earlier this year.

The recent weakness still resembles a retracement within a broader bullish move.

At this stage, it doesn't appear to signal the beginning of something more serious. The market's reaction around 9200 is now crucial and, so far, it's positive. If buyers continue defending this level, it will strengthen the bullish case.

It could also position the market for a healthy finish to the year.
