NEW YORK ( TheStreet) -- I have been warning about the risk of reversion to the mean and in my first post today I showed how 11 components of the Dow Industrial Average have either held their 200-day simple moving averages on weakness, or are now trading below its 200-day SMA.In this post I show that only one of the 24 members of the regional banking index is below its 200-day SMA. Others have been declining towards these key levels as key supports after failing to hold their 50-day SMAs. All 24 regional banks are overvalued with seven overvalued by more than 20%. All have hold ratings according to www.ValuEngine.com . Only one is slightly lower over the last 12 months while 11 are up between 21.1% and 56.1%. Only one is below its 200-day SMA. 22 of 24 are below their 50-day SMAs which indicate risk to the 200-day SMAs reflecting the continued risk of reversion to the mean.
