This week Bruce focuses on commodities and the factors that have affected various basic resources.  The worrisome spot he sees, is commodities' reverse down in relative strength vs. the money market index.  He suggests lightening up on strength because a selloff on strength generally will hold through a period of weakness when focusing on this indicator.  Associated tickers to this episode include:   (NYSE: KOL [4]), (NYSE: PYZ [5]) and (NYSE: VAW [6]).
