Stocks See Optionality. Credit Sees Risk

  • Markets diverge because equities seek upside while credit manages risk
  • Equities applaud heavy AI capex; credit fears debt coverage
  • The clearest investment signals live in the gaps between markets

When commentators say "the market expects interest rates to fall" or "the market is pricing in an AI boom," they are usually looking at a single metric: the S&P 500.

But what exactly is the market?

Truth is there is no one single market.

There are equity markets, bond markets, credit markets, commodity markets, and currency markets.

Each looks at the exact same economy through a different lens, with different definitions of risk, different time horizons, and entirely different incentives.

And occasionally, they disagree sharply (which is what I think we have today)

But these disagreements are very important to observe as an investor.

This is where the real signal lives.

Let"s explore…

Listening to Disagreement

With U.S. federal public debt topping $40 Trillion – there is a lot of talk about what we"re seeing in the debt markets (i.e., and specifically what it will cost tax payers to service that debt)

Bond yields are ripping higher – with the U.S. 30-year Treasury the highest it"s been since 2004 (chart below).

And from my perspective – higher bond yields is a very rational outcome.

Put simply – when governments become increasingly fiscally irresponsible (i.e. spending well beyond their means) — as we are seeing across Australia, the U.S., U.K. and Japan—the market demands a higher return for lending them money.

As debt investors (rightly) demanding higher risk premiums… the higher these rates will go.

But today"s missive isn"t about how reckless government spending has become (that"s a good subject for another day) — it"s more about the divergent signals markets are telling us.

For example, the equity market remains remarkably optimistic.

Major indices trade near record highs, supported by strong corporate earnings and lofty expectations around artificial intelligence (AI).

Put another way, equity investors are primarily focused on upside optionality. On the other, debt investors are asking for higher premiums based on the growing risk profile.

At this point, you might be tempted to ask:

  • Is the stock market being foolish to dismiss the downside risk? or
  • Are bond and credit markets being overly cautious?

But I think that question misses the point.

They are evaluating two entirely different risk profiles.

For example, consider equity (or stock) investors.

When you buy a share of a company, your return is ultimately tied to the upside of the business.

If earnings compound dramatically, shareholders participate in that upside. If they don"t, shareholders absorb the downside.

For example, when a company like Google spends hundreds of billions on infrastructure to unlock multi-trillion-dollar markets — shareholders have the potential to win big.

On the other hand, credit investors face an asymmetric profile.

They receive a largely fixed return, while their downside becomes significant when cash flows are no longer sufficient to service the debt.

Credit investors are not interested in the potential blue-sky optionality that "AI" may or may not bring; they only care about balance sheet leverage, free cash flow conversion, and debt coverage ratios.

The point is the equity and credit investors can look at the exact same balance sheet, cash flows and reach opposite conclusions, and both be acting completely rationally.

The Financing of AI

This brings me to the largest infrastructure build out in recent times.

What we are seeing in AI capex offers a clear case study.

Hyperscalers – such as Google, Meta, Amazon, Nvidia, Microsoft etc – are committing vast sums to data centers, chips, and power infrastructure.

While much of this initial spending was funded by existing cash reserves, debt is increasingly entering the frame.

Let"s now compare the two investors:

  • An equity investor views this CapEx as essential defense—or offensive positioning to capture the next computing paradigm.
  • A credit analyst looks at the same CapEx and calculates the burn rate, asking what happens to debt coverage if token pricing compresses before those investments yield high returns on capital.

Same set of numbers – different lens.

We saw this dynamic in the late 1990s during the buildout of fiber-optic networks.

The technology was real, and the bandwidth eventually changed the world. But the massive debt burden required to build that physical infrastructure destroyed capital long before the application layer captured the profits.

At the time, I made the mistake of only viewing the investment through an equity lens. I would have been better served by asking what the credit investor saw in the same numbers.

Structural Concentration

Beyond this – there is a second divergence happening inside equity markets themselves: extreme concentration.

This is not new news to regular readers but it"s important.

A handful of mega-cap companies now represent somewhere between 32% and 35% of major index weights.

Put another way, if you are buying an index fund today (e.g., an index ETF like SPY or VOO) – you are not really diversified.

You are making a much more concentrated bet on the largest companies than the word "index" might suggest.

Part of this is simple business excellence—these companies are among the most profitable enterprises in history.

For transparency, I own significant positions in several of these companies, including Google, Amazon and Microsoft.

My view isn"t that these are bad businesses. Quite the opposite. My point is that great businesses can still carry concentration risk at the portfolio level.

These are long term bets but not without risk.

However, what I wanted to highlight is the mechanical feedback loop at play.

As passive index funds absorb trillions of dollars in automated retirement flows, capital is increasingly allocated according to market capitalization rather than an independent assessment of valuation.

The larger a company becomes, the greater its index weighting—and the more capital is automatically directed towards it.

This can create a structural feedback loop between rising market capitalisation and future demand for the stock.

Equity indices can therefore continue rising as passive capital flows disproportionately towards the largest companies, even while credit markets begin pricing higher risks elsewhere in the economy

Now history shows that top-indexed companies rarely hold their dominant positions across decades.

As Bloomberg"s chart shows — General Electric, Exxon, Intel, and IBM were once viewed as permanent fixtures.

The lesson isn"t that today"s leaders are bad businesses, but that market dominance and long-term investment returns are two very different things.

I would be willing to bet that the Top 10 stocks by market capitalisation today will not be the same in five years.

And yet, when we buy an index today, we are implicitly making a much longer-term bet on many of the same companies continuing to dominate.

Putting it All Together

As I"ve said over the past ~15 years of writing this blog — good investing doesn"t require predicting which market will ultimately be proven right.

That is not something we can know.

However, when equity markets, bond yields, and credit spreads point in different directions, the investor"s job is to stop, look beneath the headlines, and ask why the pricing models diverge.

That was not something I understood ~28 years ago when I invested in stocks like Cisco and Intel.

I only had an equity investor"s lens.

What I should have asked is what does the person lending this company money see that I don"t? That would have been a better question.

But the real value in investing often comes from costly mistakes. They force you to look at the same problem from a different angle. For example:

  • If you find that stock prices rise while free cash flows shrink under heavy CapEx, ask why; or
  • If credit spreads widen while equity multiples expand, ask why; and
  • If market indices reach new highs while market breadth narrows, ask why.

There is no single indicator that predicts the future.

And I have no idea where interest rates, bond yields or market indices will be in one month, six months or twelve months from now. That doesn"t matter.

Markets are simply collections of imperfect signalling mechanisms. When those signals clash, don"t look for a consensus.

The signal isn"t in what any single market is saying—it lives in the gap between them.
