S&P's local government ratings may be too high according to Janney analysts. S&P has upgraded local governments at a much higher rate than Moody's since 2006, and especially since changing its rating methodology in 2013. This has led to a growing discrepancy between S&P and Moody's ratings. Janney expects this ratings divergence and issuer "rating shopping" to increase as issuers seek the most favorable ratings. While upgrades have dominated at S&P, Moody's continues to issue more downgrades, which Janney believes better reflects current credit conditions facing local governments.
