The daily dynamics for Friday night and Monday had a low of 4407 which was exceeded by about 17 and then closed back inside. Since Thursday closed below the band and I don't recall ever seeing 2 days in a row, the odds were to at least take some short profits under 4400.
Ferrera has a system where he averages NYSE advancers less decliners over a 18 day period. When it gets below -400 and you have an up close it is a buy if the market has dropped at least 14%.
Well last night got under -400 and also closed up but the market has only fallen 9%.
So it isn't a valid buy but probably worth something in the short term.
