Summary
Corporate Bonds Breadth shows how many eligible corporate bonds are advancing, declining, or unchanged over the selected comparison period.
It provides a market-wide view of bond price participation rather than focusing on a single issuer or bond issue.
Why it matters
Bond breadth can help investors understand whether price strength or weakness is widespread across the corporate bond market. Broad gains may be associated with stronger demand or changing interest-rate expectations, while broad declines may indicate wider repricing or increased risk concerns.
It can also help place the movement of an individual bond into a broader market context.
How it is calculated
A bond is generally classified as advancing when its latest eligible price is above the relevant reference price, declining when it is below that reference price, and unchanged when the prices are equal.
The calculation depends on the comparison period and on the bonds included in the selected market view.
How to read it
A larger number of advancing bonds indicates positive price breadth, while a larger number of declining bonds indicates negative price breadth. Because bond prices and yields generally move in opposite directions, positive price breadth may be associated with falling yields, while negative price breadth may be associated with rising yields.
Investors should also review maturity, credit quality, coupon characteristics, and trading activity, as different parts of the bond market can behave differently.
Things to keep in mind
Some corporate bonds trade less frequently than equities. A displayed price may therefore be unchanged for an extended period, and bonds without sufficient comparison data may be excluded.
Breadth is a summary of price direction and does not measure the size of each move, the value traded, or the credit risk of the bonds included.
