The key themes

  • Volatility prices a turbulent week: S&P 500 one-week ATM implied volatility hits 16.32%, its highest since July, while rates volatility sits at the 80th percentile of its 12-month range.
  • AI faces its biggest test: Microsoft, Alphabet and Amazon earnings put capex, future funding demands and the returns on invested capital under the microscope after heavy selling across the AI ecosystem.
  • The global AI trade is in play: SK Hynix, Samsung and Chinese technology earnings offer important read-throughs for memory stocks, semiconductors and robotics.
  • Five major central banks take centre stage: The Fed, ECB and BoJ are expected to hold, while the BoC and RBNZ are priced to hike. Forward guidance could matter more than the decisions themselves.
  • Australian CPI could clinch an RBA hike: A 1% quarterly trimmed-mean inflation print could reinforce expectations of a 25bp increase on 3 November, with implications for AUD, rates and equities.

The market's machinery moves into overdrive

The cogs of market structure are beginning to turn, and with the sheer weight of event risk ahead, they could quickly shift into overdrive. Investors face an extraordinary concentration of earnings, central bank decisions and economic releases, all against a backdrop of deteriorating AI sentiment and increasingly sensitive positioning.

It's little surprise that S&P 500 one-week at-the-money implied volatility has risen to 16.32%, its highest since July. FX implied volatility has also edged higher, while interest rate volatility sits at the 80th percentile of its 12-month range.

S&P500 earnings deluge: The market wants returns, not just ambition

Last week's liquidation across neoclouds, hyperscalers and Meta has sharpened the market's focus on AI investment economics. Meta's capex commitments, its proposed Class C share structure and reports of a potential $40 billion capital raising have intensified scrutiny of how the next phase of AI infrastructure investment will be funded.

The SOX index (an index of major semiconductor equity) has retreated towards its 200-day moving average and while finding pockets of buying support, there remains limited appetite to go hard on building an extensive long positioning, at this stage. This isn't exclusively a US phenomenon, with Hong Kong's technology sector also under considerable pressure, having undergone a 42% drawdown since Sept 2025, and Japan's tech plays not looking overly flash either... 

Now come Microsoft, Alphabet and Amazon. The market knows hyperscalers are set to keep the spending intensions pushing ever higher. What it increasingly wants to know is when that spending translates into sustainable returns, and how much additional capital will be required to get there.

Their capex guidance, funding commentary, and evidence of AI monetisation will be central to the reaction. Given their high weightings on the S&P500 & NAS100 indicies, the consequences could extend beyond technology into broader equity sentiment, Treasuries and rates.

The AI trade goes global

The earnings spotlight also falls on Korean memory heavyweights SK Hynix and Samsung Electronics, alongside developments at China's CXMT. Their commentary on DRAM pricing, capacity, and demand could materially influence sentiment towards Micron and the wider memory complex.

With Micron in a closed trading window, Pepperstone's 24-hour CFDs may attract additional attention from traders seeking to manage exposure ahead of the US pre-market reopening.

China's Unitree also commands attention, particularly following the release of its H2-X Kung Fu Legend Guardian humanoid robot. One just has to watch the promo videos showing what this model can do immediately backs the view that Sarah Connor from Terminator 2 was wise beyond her years.

Meanwhile, Anthropic's potential public S-1 filing could start the countdown towards its institutional roadshow and eventual listing. A major IPO could also draw liquidity away from other AI holdings. OpenAI presents a different funding dynamic, with reports of a $30 billion capital raise at a valuation of around $1.3 trillion.

Five G10 FX central banks, but the real trade is in the guidance

The Fed, ECB and BoJ are expected to leave policy unchanged, while the Bank of Canada and RBNZ are expected to deliver 25bp hikes.

The decisions themselves may be largely discounted. The real issue that could move the dial in short-term rates, and by extension, how policymakers shape expectations for subsequent meetings and whether markets need to reprice the forward rates curve.

That repricing could generate significant movement in front-end bonds and currencies. XAUUSD will be particularly sensitive to these developments, with both spot and futures testing the major support levels established between July and August. A decisive daily close below this support zone would be a meaningful technical development, potentially opening the door to further downside. The significance of these levels certainly hasn't gone unnoticed by our client base, with trading volumes surging as spot gold broke below $4,000.

US consumer confidence, core PCE inflation and Q3 GDP add further complexity, although the Fed's communication may ultimately dominate the macro discussion.

Australian CPI could force the RBA's hand

Wednesday's Australian Q3 CPI report is potentially decisive. Consensus expects trimmed-mean inflation of 3.6% year-on-year and 1% quarter-on-quarter, while AUD OIS pricing implies roughly a one-in-three probability of a 25bp RBA hike on 3 November.

A 1% quarterly core inflation print may be enough to convince the market that the RBA has one more hike to deliver.

The AUD has been making stready progress higher against the USD, but the crosses arguably offer more interesting tactical opportunities. Short EURAUD, alongside EURCAD and EURCHF, offers exposure to improving China sentiment and the persistent French sovereign risk premium.

Moody's decision to leave France's rating unchanged may provide some relief, but the underlying concerns around French fiscal credibility remain.

GBPAUD also warrants attention, although sterling faces its own fiscal test from the UK budget and the gilt market's assessment of the government's plans.

A week for traders, not complacency

The combination is formidable: mega-cap earnings, AI funding concerns, global semiconductor results, five major central bank meetings and potentially market-moving inflation and growth data.

The danger isn't simply that markets move sharply. It's that one catalyst changes the interpretation of the next, creating feedback loops across equities, rates, FX and volatility.

The technical damage across AI is real, but so is the potential for strong earnings to reverse positioning quickly.

This is a week to respect price, stay flexible and trade the reaction rather than become wedded to a forecast.

Good luck to all.
