ASX Earnings Season Paradox: Copper Fuels BHP's Results, JB Hi-Fi Suffers Consumer Demand Slowdown
The August 2026 earnings season on the ASX has been marked by a paradoxical relationship between reported results and share price movements. Despite some companies delivering solid absolute results, their stock prices have declined sharply if they failed to exceed already-elevated expectations.
This phenomenon is attributed to the 'expectation gap', the distance between what the market had priced in before a result and what was actually delivered. In this season, analyst consensus has tended toward pessimism due to repeated earnings downgrades across multiple sectors, leading to defensive investor positioning.
BHP Group's fiscal 2026 result is a notable example of this dynamic. The company reported a 30% increase in underlying net profit after tax to $13.2 billion and a 15% increase in total revenue to $58.8 billion. However, its shares rose only 3% on the day due to high expectations.
The driving force behind BHP's result was copper, which surpassed iron ore as its single largest earnings contributor for the first time. This structural milestone has important implications for how analysts model BHP's future cash flows. Copper demand is tied to electrical infrastructure, electric vehicle manufacturing, and renewable energy systems, making it a structurally different demand profile compared to iron ore.
Despite the solid result, BHP's valuation remains concerning due to its stretched price. The company's shares trade at a 38% premium to Morningstar's fair value estimate of $46 per share, which reflects the time value of money and anticipated non-core asset disposals. Investors buying at current levels are essentially betting that copper prices remain elevated for a sustained period beyond what fundamental modelling supports.
JB Hi-Fi's full-year numbers were also scrutinized by investors. The company reported 5% growth in group sales, but its shares declined 12% due to concerns over consumer demand slowdown. Australian same-store sales growth collapsed to effectively flat year-on-year in the June 2026 quarter, and July 2026 trading deteriorated further.
The market was selling JB Hi-Fi's future prospects rather than its past results. Three structural forces are compressing consumer electronics demand: elevated borrowing costs, memory chip price inflation, and sentiment erosion ahead of income erosion. These factors create a self-reinforcing cycle where sentiment weakness begets actual spending decline.
