Macro and portfolio glossary

These definitions clarify common terms in macro research, portfolio monitoring, and investment data systems. They describe concepts and measurement limits rather than providing market forecasts.

Regime shift

A sustained change in the economic conditions or relationships used to describe market behavior. A regime shift is model-dependent and cannot be established by one unusual trading day.

Macro regime

A recognizable combination of growth, inflation, policy, and financial conditions over a period. The definition should identify observable variables rather than rely on a descriptive label alone.

Yield curve

The relationship between yields and maturities for a defined group of debt instruments at a given time. Comparisons require consistent credit quality and quotation conventions.

Yield-curve inversion

A condition in which the shorter-maturity yield exceeds the longer-maturity yield for a specified comparison. Different maturity pairs can invert at different times.

Term premium

The compensation embedded in a longer-term bond yield for bearing interest-rate risk over time, beyond expected future short rates. It is estimated rather than directly observed and can be negative.

Real interest rate

An interest rate adjusted for inflation. An ex ante real rate uses expected inflation, while an ex post rate uses realized inflation.

Breakeven inflation

The yield difference between comparable nominal and inflation-linked bonds. It reflects inflation expectations as well as inflation-risk and liquidity effects, so it is not a pure forecast.

Liquidity

Liquidity can describe the ease of trading an asset without a large price impact or the availability of funding. The intended meaning should be specified because these mechanisms differ.

Risk-on/risk-off

Shorthand for broad changes in willingness to bear financial risk. It summarizes observed behavior rather than defining a rule that every asset must follow.

CPI vs PCE

CPI and the PCE price index are different U.S. consumer-price measures with different coverage, weighting, and calculation methods. They should not be substituted for one another without explaining the distinction.

Core inflation

A measure that excludes selected volatile categories, commonly food and energy, to help examine underlying price movements. It does not mean those costs are unimportant to households.

Nonfarm payrolls

An estimate of U.S. payroll jobs outside farming and certain other excluded categories, drawn from the establishment survey. Jobs are not the same measure as employed people in the household survey.

PMI

A purchasing managers’ index summarizes survey responses about business conditions. Many headline diffusion indexes use 50 as the no-change threshold, but methodology and coverage should be checked for the specific index.

GDP

Gross domestic product measures production within an economy over a period. Nominal GDP uses current prices, while real GDP adjusts for price changes.

FOMC

The Federal Open Market Committee is the Federal Reserve body responsible for U.S. monetary-policy decisions. Its statements, minutes, and projections convey different information and appear on different schedules.

Quantitative tightening

A reduction in central-bank securities holdings, often through reduced reinvestment of maturing assets. Its effects depend on the implementation and the wider funding environment.

Quantitative easing

Central-bank asset purchases intended to ease financial conditions. The transmission depends on the assets purchased, market conditions, and expectations about future policy.

Carry

The income or financing-related return from holding a position, separate from some forms of price change. The precise definition varies by instrument and can include borrowing costs or derivative roll effects.

Duration

A measure related to the timing of bond cash flows and sensitivity to yield changes. Modified or effective duration approximates price sensitivity under its stated assumptions.

Convexity

The curvature of the relationship between bond prices and yields. It helps explain why a duration-only estimate becomes less accurate for larger yield moves.

Credit spread

The yield difference between a debt instrument and a specified benchmark. It can reflect credit risk, liquidity, optionality, and market conditions rather than default risk alone.

Factor exposure

The sensitivity or allocation of a portfolio to a defined driver such as market returns, value, size, or interest rates. An estimated exposure depends on the model and sample.

Beta

An estimated sensitivity of an asset’s returns to a specified benchmark’s returns. Beta depends on the benchmark, observation frequency, and estimation period.

Correlation breakdown

A change in the historical co-movement between variables or assets. Apparent breakdowns can reflect genuine structural change, noisy estimation, or a different measurement horizon.

Drawdown

The decline from a prior peak to a subsequent lower portfolio or asset value. The result depends on the valuation frequency and whether distributions are included.

Volatility

A measure of variability in returns or another series. Historical volatility describes observed variation, while implied volatility is inferred from option prices under a model.

VIX

An index derived from S&P 500 option prices that represents market-implied near-term volatility under its methodology. It is neither a direct forecast of stock-market direction nor a measure of every form of risk.

Dollar index

An index measuring the U.S. dollar against a specified currency basket. Different dollar indexes use different currencies and weights, so the provider and methodology matter.

Terms of trade

The relationship between an economy’s export prices and import prices. An improvement means export prices rise relative to import prices under the chosen measure.

Stagflation

A combination of weak economic activity and persistent inflation. The label does not have a single universal numerical threshold.

Disinflation

A decline in the rate of inflation. Prices can continue rising during disinflation, just more slowly.

Deflation

A decline in the general price level over a specified period. Falling prices in one category do not necessarily establish economy-wide deflation.

Soft landing

A scenario in which inflation moderates without a severe contraction in economic activity. It is an outcome description or scenario, not a guarantee implied by a particular data release.

Feature vector

An ordered set of attributes representing an entity or observation for analysis. Meaning depends on feature definitions, units, scaling, and time alignment.

Data pipeline

A sequence of steps that collects, validates, transforms, and delivers data. Reliable pipelines preserve source information and make failures or missing observations visible.

API

An application programming interface defines how software requests or exchanges information with another system. API access remains subject to the provider’s technical limits and licensing terms.

Portfolio-weighted news

News prioritized partly by the holdings and exposures in a portfolio. Weighting can incorporate materiality, source quality, and novelty as well as position size.

SMIF

A student-managed investment fund is an educational program involving portfolio research and management under defined oversight. Programs differ in authority, mandate, and whether they manage real capital.

Family office

An organization or arrangement managing financial and related affairs for one or more families. Services and investment responsibilities vary substantially.

Observation date

The date or period to which a data value refers. It can differ from the publication date and the time a monitoring system retrieved it.

Release vintage

The version of a dataset available at a particular publication time. Vintage data help reconstruct what an analyst could actually have known then.

Seasonal adjustment

A statistical process intended to remove recurring calendar-related patterns from a series. Adjusted figures can be revised as new information changes the estimated seasonal pattern.

Basis point

One hundredth of a percentage point. A yield rising from 4.00% to 4.25% has increased by 25 basis points.

Percentage point

The arithmetic difference between two percentages. A rate rising from 2% to 3% increases by one percentage point, which is a 50% relative increase.

Discount rate

The rate used to translate future cash flows into a present value. The appropriate rate depends on the cash flows and their risk, currency, and timing.

Yield

A return measure quoted according to a specified convention. Coupon yield, current yield, and yield to maturity describe different calculations.

Nominal value

A value measured in current monetary units without adjustment for inflation. Comparisons across time can therefore reflect both price changes and changes in real activity.

Real value

A value adjusted for changes in prices using a defined deflator. The chosen price measure affects the interpretation.

Risk premium

Expected compensation for bearing a specified asset risk relative to a defined benchmark. It is not guaranteed realized income.

Market depth

The quantity available to transact at different prices in a market. Displayed depth can change rapidly and does not necessarily represent all potential liquidity.

Funding stress

Difficulty obtaining financing on acceptable terms. It can appear through prices, collateral requirements, borrowing availability, or settlement conditions.

Leading indicator

A series that tends to move before a specified economic activity measure. The relationship is empirical and does not guarantee future timing.

Coincident indicator

A series that tends to move with the activity being measured. Its publication can still lag the period it describes.

Lagging indicator

A series that tends to change after the underlying economic activity. It can still help establish persistence or confirm an earlier interpretation.

Look-ahead bias

A historical analysis error caused by using information unavailable at the simulated decision time. Revised macro data and future constituent lists are common examples.

Overfitting

Fitting a model to historical noise or sample-specific patterns rather than a durable relationship. Strong in-sample results can coexist with weak performance on genuinely unseen data.

Invalidation condition

An explicit observation or development that would undermine a research interpretation. It helps make a thesis testable without guaranteeing a trading outcome.

How should I use a macro glossary while reading research?

Use a macro glossary to check the exact meaning of a term before interpreting a chart or conclusion. Then inspect the source methodology, because an operational definition can differ from everyday usage. Words such as liquidity, yield, and real can refer to different measures depending on the instrument or dataset.

Write down the series identifier, units, and comparison period beside unfamiliar terms. A definition helps frame a question but does not replace the original data documentation.

Are macro regime labels standardized?

Macro regime labels are not universally standardized. Different analysts use different variables, thresholds, horizons, and methods to describe growth, inflation, policy, or market relationships. Compare the underlying definitions before comparing labels, and avoid treating a shared name as proof that two systems are measuring the same economic condition.

A label should have observable entry and exit criteria. Otherwise it is difficult to distinguish a changed market from a changed description.

What is the difference between a definition and an investment signal?

A definition explains what a concept or measure means, while an investment research signal applies a rule to observations in a particular context. Understanding duration or inflation does not establish a profitable strategy. Signals require explicit assumptions, data validation, and evaluation against evidence that was not used to design them.

Keep descriptive statements separate from estimates about future behavior. A familiar term can still be used in an unsupported argument.
