Direct Answer
The yield spread between high-yield (junk) bonds and investment-grade bonds, as used for the junk bond demand component of the CNN Fear and Greed Index. It measures the extra yield investors require for taking lower-credit risk, relative to safer corporate bonds. A narrow spread means investors are willing to hold riskier bonds without demanding much extra yield, which is read as strong risk appetite; a wide spread means demand for junk bonds is weak.
Junk Bond Demand Gauge: Formula, Meaning, Signals, Examples and How to Use It
How Is Junk Bond Demand Gauge Calculated?
The yield spread between high-yield (junk) bonds and investment-grade bonds, as used for the junk bond demand component of the CNN Fear and Greed Index. It measures the extra yield investors require for taking lower-credit risk, relative to safer corporate bonds.
Formula: Spread = high-yield bond yield - investment-grade bond yield
Inputs:
- High-yield bond index yield
- Investment-grade bond index yield
Worked example. If high-yield bonds yield 7.8 percent and investment-grade bonds yield 5.1 percent, the spread is 2.7 percentage points. The inputs are illustrative numbers, not market data.
Reading it. A narrow spread means investors are willing to hold riskier bonds without demanding much extra yield, which is read as strong risk appetite; a wide spread means demand for junk bonds is weak. The direction matters more than the level.
Limits. It compares two corporate indexes, unlike the credit spread to Treasuries, so changes in the high-quality benchmark also move it. Index composition and duration differences distort comparisons over time.

How to use Junk Bond Demand Gauge
A narrow spread means investors are willing to hold riskier bonds without demanding much extra yield, which is read as strong risk appetite; a wide spread means demand for junk bonds is weak. The direction matters more than the level. A reading alone is never a buy or sell signal; it needs context from price structure, volume, volatility and the broader market regime.
Strengths
- Using two corporate indexes keeps both legs as credit instruments, so the gap isolates the quality difference.
- The spread is the extra yield for lower credit quality, so it reads directly in yield points.
- Reproducible when the formula and data convention are fixed.
Weaknesses and limitations
- High-yield indexes carry a larger share of energy and other cyclical issuers, so commodity moves can widen the gap with no change in mood.
- Yield rather than price is used, so a bond near default with a very high yield can pull the index average up sharply.
- Correlated indicators can create false confidence by repeating the same underlying information.

Frequently Asked Questions
Is Junk Bond Demand Gauge a buy or sell signal?
No. A narrow spread means investors are willing to hold riskier bonds without demanding much extra yield, which is read as strong risk appetite; a wide spread means demand for junk bonds is weak. It compares two corporate indexes, unlike the credit spread to Treasuries, so changes in the high-quality benchmark also move it. A trade built on it still needs a trigger, an invalidation rule, a position size and realistic execution assumptions.
What is the best setting for Junk Bond Demand Gauge?
Junk Bond Demand Gauge is computed from high-yield bond index yield; investment-grade bond index yield, so the choices that matter are the data convention and the window it is read over. Test those across instruments, regimes and out-of-sample periods instead of fitting one historical winner.
Can Junk Bond Demand Gauge be used by itself?
It compares two corporate indexes, unlike the credit spread to Treasuries, so changes in the high-quality benchmark also move it. Index composition and duration differences distort comparisons over time. For that reason it is read next to measures of direction, participation, valuation, liquidity and risk, not alone.
Does Junk Bond Demand Gauge work on every timeframe?
The calculation (Spread = high-yield bond yield - investment-grade bond yield) can be run on any bar size, but behavior is not portable: a reading on a five-minute chart describes a very different market window from the same reading on a daily chart. Validate the exact timeframe before relying on it.
Why does Junk Bond Demand Gauge give false signals?
High-yield indexes carry a larger share of energy and other cyclical issuers, so commodity moves can widen the gap with no change in mood. Yield rather than price is used, so a bond near default with a very high yield can pull the index average up sharply. Lag, noise and regime changes add to this, because market participants react to new information after the reading is calculated.
How should Junk Bond Demand Gauge be backtested?
Rebuild Junk Bond Demand Gauge from high-yield bond index yield using point-in-time data, write the rules before testing, include delisted securities where relevant, model realistic fills and costs, reserve a validation sample and compare with a simpler baseline.
