Starting from zero: why this site exists and where I think markets are

Why this site exists

I’m building a real portfolio from A$10,000 and documenting everything in public: every trade, every valuation model, every mistake. Returns are measured against the S&P 500, and the full record lives in a public GitHub repository, so you don’t have to take my word for any of it.

The research is AI-assisted and human-led. AI does the heavy lifting on research and coding; I make every judgement and every decision.

About me

How I invest

Where we are

Bond yields are at multi-decade highs almost everywhere. Government bond yields are the baseline every valuation is measured against. When they rise, future earnings are worth less today, and the hit is biggest for companies whose value sits far in the future.

The drivers are heavy government borrowing, an oil shock that has reignited inflation, and central banks expected to stay tighter for longer. In Japan, the 10-year yield has passed 3% for the first time since 1996. That makes it less attractive to borrow in yen to invest abroad, a trade that has quietly supported global markets for years. The yen is still weak, so this is a risk that’s building, not one that has broken yet.

Central banks are hiking again. The Fed raised rates on 16 September to 3.75–4.00%, its first hike since 2023. The RBA is at 4.35% after three hikes this year, and markets price a fourth for 29 September. Inflation is proving hard to control: Australian headline inflation was 3.6% in July.

The Middle East remains the main source of inflation risk. Markets have learned to live with the conflict, but renewed US–Iran strikes pushed oil back above US$100 a barrel this month. Talks on a phased deal are the main thing holding it back.

AI is absorbing an enormous share of the world’s capital. Microsoft, Alphabet, Amazon and Meta are guiding to about US$730bn of capex this year, with projections above US$930bn for 2027. AI companies’ borrowing is now large enough to push up long-term bond yields alongside governments’. AI and governments are competing for the same pool of capital.

Stocks are priced for a lot to go right. The gap between what US stocks earn and what 10-year Treasuries pay has compressed to historic lows. Bonds are now a genuine alternative to equities for the first time in years.

The world is fragmenting. Globalisation is giving way to national priorities, trade wars and industrial policy, with the US on one side and much of the rest of the world on the other. The result is higher costs, more supply-chain duplication and more government spending, all of which keep inflation and borrowing elevated.

My outlook

Short term, to early 2027: cautious. I expect two more Fed hikes and three more RBA hikes. In Australia, I think property, jobs and inflation will weaken enough for the RBA to start cutting around mid-to-late 2027. My US view is more hawkish than the Fed’s own median projection of 4.1% at the end of 2027.

Most importantly, I don’t think equities have priced this in. At today’s bond yields, my valuation models put most AI leaders below their current share prices. The market is accepting a thin return premium over bonds, which leaves little cushion if growth slows.

Scenario Estimated Probability What happens Equities
Bear: the bond rout bites ~25% Yields keep rising, hikes go further than I forecasted, the yen carry trade unwinds, AI spending pauses Fall 20%+
Base: higher for longer, then relief ~55% Fed +2, RBA +3; growth slows; earnings grow but valuations compress; RBA cuts from mid-to-late 2027 Choppy, with a 10–15% pullback along the way
Bull: soft landing ~20% A US–Iran deal lowers oil, inflation eases, hikes end early, AI earnings keep beating Keep rising

Medium term, three to five years: constructive, especially on AI. I use AI every day, including to build this site and its models, and the productivity gains are real. I think there’s still room to grow at current valuations for companies turning that into earnings now.

What would change my mind on AI: hyperscalers cutting capex guidance, AI revenue failing to keep pace with the spending, or GPU rental prices falling sharply.

What this means for my portfolio

I’m starting in cash. I’ll deploy it in thirds as these conditions are met:

  1. The Fed and RBA signal the end of their hiking cycles.
  2. Bond yields stabilise: the US 10-year yield back below 4.75%.
  3. Equities re-price: the S&P 500 10% or more below its peak.

Individual stocks can trigger earlier if they reach my entry levels. For example, TSMC at or below about US$420.

What I’m looking for: AI exposure with earnings I can see now rather than a decade away, and less-covered small and mid caps in the US and on the ASX.
