The risk off selling in U.S. and global equity markets start the grain and livestock futures all lower.  Brad Kooima of Kooima Kooima Varilek says the protein sector is down with ideas of slower demand.  The cattle market selloff started late last week and currently the October live cattle are below the 100 day moving average.  Cash was steady to $2 lower so what will the plunge in futures mean for cash cattle trade this week?  Grains start lower with risk off selling but corn is trying to claw back and is above $4 on the December but can it hold?
