Macro Metrics on Investing

Most investors watch prices. They scroll screens, track daily moves, react to headlines.

That's looking at the symptom, not the disease.

The real signal lives in the metrics underneath — valuation, stress, liquidity, and positioning. These move slower than prices but they predict them. Once you know where stress lives and how much it can move, price action stops being a mystery and becomes mechanical.

Here's what actually matters across asset classes.

Equities: Valuation & Risk Premium

Buffett Indicator (Market Cap / GDP) — The total value of the stock market divided by GDP. Above 100% means expensive territory. Way above 100% (like 150%+) means you're in bubble zone. It's not a timing tool, but it tells you how much pain is built in when things reset. Current levels matter less than trajectory.

Shiller PE (CAPE) — 10-year cyclically-adjusted P/E ratio. Smooths out earnings volatility by averaging the last decade. Under 20 is historically cheap, over 30 is expensive, over 35 is bubble. It's slow to change, which is its strength — it filters out daily noise.

Equity Risk Premium — The difference between expected stock returns and Treasury bond yields. When stocks are expensive relative to bonds (low premium), it's priced in. When the premium widens (stocks become cheap relative to bonds), there's opportunity. This drives rotation between asset classes.

Margin Debt to GDP — How much leverage is in the system. High margin debt means crowded positions and forced selling when things move. It's the "leverage timer" — tells you how much downside pain is forced rather than optional.

Foreign Exchange: Real Rates & Supply Shocks

Real Effective Exchange Rate (REER) — Your currency's value adjusted for inflation relative to trading partners. Overvalued currency is a headwind; undervalued is a tailwind. Look at the trend, not the level.

Terms of Trade — The ratio of export prices to import prices. When your exports are valuable relative to imports, you have room to run. When inverted, you're getting squeezed.

2-Year Yield Differentials — The most predictive FX metric. Higher 2-year yields attract capital; lower ones repel it. Track the spread between two currency pairs and it predicts 3-6 month moves better than anything else.

Sovereign CDS Spreads — The cost to insure government debt. Widening spreads mean rising default risk. For developed markets, they telegraph recessions. For emerging markets, they telegraph crisis.

Commodities: Supply Signals & Macro Health

Roll Yield (Contango vs Backwardation) — Futures contracts are more expensive (contango) when supply is ample and farther-out contracts discount that. Futures are cheaper (backwardation) when supply is tight and immediate delivery is at a premium. Backwardation = supply squeeze = buy signal.

Copper-to-Gold Ratio — Copper is industrial (expansion signal), gold is safe-haven (contraction signal). High ratio = expansion, low ratio = contraction. It's a barometer of growth expectations. Watch it, not individual prices.

Gold-to-Oil Ratio — When this exceeds 25-30, something's broken. It means you're willing to pay a huge premium for safety relative to energy. It's a recession warning flag that works 3-6 months ahead of the actual downturn.

Crack Spreads (refiners' margins) — The difference between crude oil price and product prices (gasoline, heating oil). Tight spread means demand is weak. Wide spread means refineries are printing money and capacity constraints exist. It predicts energy market direction.

Cross-Asset: The Macro Backbone

Global M2 Liquidity — All central banks' monetary supply combined. When M2 is expanding, risk assets work. When it's contracting, they struggle. It's not about levels, it's about the rate of change. Deceleration is the killer.

High Yield Credit Spreads — The difference between junk bond yields and Treasury yields. When spreads tighten, credit is easy and risk appetite is high. When they widen, stress is rising and defaults are coming. Watch the trend, especially for acceleration — that's your warning.

VIX Futures Curve — Plot 1-month, 3-month, and 6-month VIX futures. Normal market: upward sloping curve (farther out is higher volatility expectations). Panic market: inverted curve (immediate panic but expectations of stability ahead). Inverted VIX curve is a reversion signal — volatility spikes are priced in and likely temporary.

How to Actually Use These

Don't chase the numbers. Track them weekly or monthly in a simple spreadsheet. Watch for changes in direction more than absolute levels.

When Buffett Indicator is rising, margin debt is high, and equity risk premium is compressed — you're expensive. When credit spreads widen and liquidity decelerates, you're crowded. Those are the times to be cautious.

When valuations reset (CAPE drops 30%+ in a month), margin debt forces liquidations, and spreads blow out — that's fear priced in and opportunity alive.

The price chart will lie to you every time. These metrics tell you what's actually happening underneath — valuation, stress, and positioning.

Stop looking at what the market is doing and start looking at what it can do.

That's where the edge is.
