The sensitivity of corporate bonds to the economic environment essentially depends on their time to maturity. In the short term, default risk for investment grade corporate issuers is primarily due to nonsystematic factors, for example, cases of fraud or litigation. Over longer term horizons, conversely, systematic factors tend to have a higher impact on the default probability of corporate issuers. Changes in the economic environment and business risks in the sense of adverse industry trends or increasing competition are major drivers of credit risk and hence for spreads in the longer term. Therefore, one would expect the spreads of long and intermediate investment grade corporate bonds to be more sensitive to indicators of economic activity than short-term bonds. This implies that credit curves should flatten when the economic outlook improves. Rising confidence in the corporate sector additionally spurs investors’ willingness to take on more spread duration. Consequently, in periods of spread tightening investors should expect credit curves to flatten. In other words, the slope of the credit curve and the level of credit spreads are positively correlated for investment grade issuers.

The rating outlook of both rating agencies (S&P and Moody’s) can be another criterion to choose between industries. If companies with a positive rating outlook outweigh the companies with a stable or negative rating outlook within an industry, it can be a good indicator for favorable industry dynamics, even if we have to recognize that ratings are sometimes lagging indicators for credit quality. A diversified portfolio should overweight the industries with a positive rating outlook and underweight industries with a negative rating outlook if the whole credit market experiences a “Flight-to-Quality.” During a market phase with a higher risk appetite, fundamental factors like the rating trend in a specific industry might not be the primary decision criterion for a sector positioning and other factors like valuation
will play a bigger role.
