Manufacturing PMIPMI — Purchasing Managers' Index. Above 50 = the sector is expanding vs last month; below 50 = contracting. A timely read on activity. is below 50 but rising.
Why: Activity is still contracting in absolute terms (below 50), but the rate of contraction is easing — the second derivative has turned up, which historically clusters near cyclical lows.
Forward-looking investors start to price the trough.
Why: Markets discount the turn before it completes; an improving-but-sub-50 PMI often coincides with the low in cyclical risk assets, well before the PMI itself crosses back above 50.
Early-cycle cyclicalscyclicals — Sectors whose earnings rise and fall with the economic cycle — industrials, materials, energy, consumer discretionary. and small-caps tend to lead off the low; defensivesdefensives — Sectors whose demand is steady through the cycle — consumer staples, utilities, healthcare. They outperform when growth slows.' relative edge fades.
Why: The names most beaten down in the contraction have the most operating leverage to even a marginal improvement, so they re-rate first when the deterioration stops.

Hurts

Caveat: A one-month uptick that doesn't persist is a head-fake; the turn needs follow-through, and a sub-50 level still means activity is contracting in absolute terms — this is an inflection signal, not an all-clear.

House-view hook — empty (textbook default; Stephen's view bakes in here).

What would change the read

Inflation surprise (upside) Core inflation is steady, so the upside-surprise channel is quiet. It would fire on a core reading ≥0.2pp above the prior — watch it because that is what forces a central bank to stay restrictive and pressures the longest-duration assets first.
Inflation surprise (downside / disinflation) Core inflation isn't cooling fast enough to trigger the disinflation channel. A fall of ≥0.2pp would fire it — worth watching because it is the cleanest tailwind for long-duration growth and government bonds.
Monetary easing (rate cut) The policy rate is on hold, so the easing channel is dormant. A cut would fire it — it matters because the first cut of a cycle typically broadens a rally and pressures the currency.

M6Growth slowdown (deepening contraction)

Trigger: pmi_mfg: 50.1 → 49.3 (-0.8)

Manufacturing PMI is below 50 and still falling.
Why: Below 50 means more firms are contracting than expanding; *falling* means the contraction is deepening, not bottoming — that combination is what leads earnings revisions down.
Investors rotate toward defensives and government bonds.
Why: When growth is deteriorating, steady-demand sectors (staples, utilities, healthcare) hold earnings better, and government bonds act as a hedge that rallies if the slowdown deepens further.
Cyclicals, small-caps, EM and industrial commodities underperform.
Why: These are geared to the physical cycle and to leverage, so worsening activity hits their earnings and risk appetite hardest; commodity demand softens with industrial output.

Caveat: A shallow dip just below 50 that quickly reverses ('soft patch') doesn't trigger the full defensive rotation; the level must persist.

House-view hook — empty (textbook default; Stephen's view bakes in here).

What would change the read

Monetary easing (rate cut) The policy rate is on hold, so the easing channel is dormant. A cut would fire it — it matters because the first cut of a cycle typically broadens a rally and pressures the currency.
Monetary tightening (rate hike) The policy rate is steady, so the tightening channel is dormant. A hike would fire it — watch it because it hits long-duration growth, long bonds, and gold first.
Growth acceleration (expansionary PMI) Manufacturing isn't both expanding and accelerating, so the growth-acceleration channel is dormant. A rising PMI back above 50 would fire it — it matters because it's the signal to rotate from defensives toward cyclicals.

M9Long-end yield spike / term-premium rise

Trigger: yield_10y: 2.06 → 2.24 (+0.18)

⚠ Fired on a stale print: yield_10y as of 2026-01-01 (10d old). The change may predate current conditions — treat as provisional.

The 10-year yield jumps.
Why: The long yield sets the cost of long-term money for the whole economy and the discount ratediscount rate — The rate used to convert a future cash flow into today's value. A higher discount rate makes far-off cash flows worth less now. for the longest cash flows.
The discount rate on all long-dated cash flows rises.
Why: Equity valuations and long-bond prices are present values of distant cash flows; a higher long yield shrinks those present values.
Long-duration growth equities compress, long bonds fall, gold is pressured.
Why: The longest-duration assets are most exposed to the discount-rate move, and a higher real yieldreal yield — The yield after subtracting expected inflation — what a lender actually earns in purchasing power. Real yield ≈ nominal yield − expected inflation. raises the opportunity cost of holding non-yielding gold.

Caveat: Granularity is daily, so a single-session jump can be noise; a sustained multi-session move is the real signal. Distinguish a growth-driven rise (risk-on) from a supply/term-premium rise (risk-off).

Concept libraryL3

Terms marked ✓ are linked inline above — click any dotted term in the text to expand it in place.

2s10s: The gap between the 10-year and 2-year government bond yields. Positive = normal upward-sloping curve; negative ('inverted') = a classic late-cycle/recession warning.
PMI ✓: Purchasing Managers' Index. Above 50 = the sector is expanding vs last month; below 50 = contracting. A timely read on activity.
carry trade: Borrowing in a low-rate currency (long the yen's case) to buy higher-yielding assets elsewhere. It unwinds violently when the funding rate rises or the funding currency strengthens.
credit impulse: The change in the flow of new credit into an economy. A rising impulse front-runs stronger demand for commodities and cyclical goods, with a lag.
cyclicals ✓: Sectors whose earnings rise and fall with the economic cycle — industrials, materials, energy, consumer discretionary.
defensives ✓: Sectors whose demand is steady through the cycle — consumer staples, utilities, healthcare. They outperform when growth slows.
discount rate ✓: The rate used to convert a future cash flow into today's value. A higher discount rate makes far-off cash flows worth less now.
disinflation: Inflation that is still positive but falling (prices rising more slowly) — distinct from deflation, where prices actually fall.
duration: How sensitive an asset's price is to interest rates. 'Long-duration' assets (long bonds, fast-growing stocks whose profits are years away) move most when rates change.
net interest margin: The spread a bank earns between what it charges on loans and pays on deposits. Higher short rates / steeper curves tend to widen it.
nominal yield: The headline interest rate on a bond, before subtracting inflation.
policy rate: The interest rate a central bank sets directly (e.g. the Fed funds rate, the ECB deposit rate, China's LPR). It anchors all other rates.
rate path: The market's expectation of where the policy rate goes over the next year or two — not just today's level, but the whole expected trajectory.
real yield ✓: The yield after subtracting expected inflation — what a lender actually earns in purchasing power. Real yield ≈ nominal yield − expected inflation.
term premium: The extra yield investors demand to hold a long bond instead of rolling short ones — compensation for tying money up and for issuance/inflation risk.
