Specifically, the differences in market-derived credit risk signals between large and small banks, REITs, and utilities are notably slim. In these sectors, expansion may necessitate heavy debt issuance while balance sheet composition is legally restrained. This contrasts with highly innovative industries that are able to produce windfall profits and expand without cranking up leverage.Credit risk signals converge when revenue is less concentrated Recently we wrote about US corporate sectors where there were large positive gaps in credit risk signals between the high and low revenue firms in a sector . Now we will examine the flip side of that scenariosectors with little to negative difference between the market-implied ratings of the highest revenue firms within a sector and all other firms.Of the 97 sectors we examined, 26 had a difference in the median EDF (Expected Default Frequency)-Implied Rating among the top four revenue firms and that of the other firms in the sector of one rating notch or less (Figure 1). For example, in the commercial banking sector, the top four revenue firmsled by JPMorgan Chase&Co.had a median EDF-implied rating of Baa1, just one notch above the median Baa2 rating of the other 314 firms in the sector.MOODY'S ANALYTICS CROSS-SECTOR2 31 May 2016 Market Comment: Skimpy Profits and Tight Regulations Constrain Credit QualityMOODY'S ANALYTICS CROSS-SECTOR3 31 May 2016 Market Comment: Skimpy ...
