16 years after the head & shoulders top in May 1998, Du Pont's price hit the resistance on the downtrend channel making a distinctive LOWER HIGH. Well supported and confirmed by MACD not making higher high. I foresee that the next window of support is between 40 - 50 in time to come. My opinion is on a short side, but must wait patiently as there is a possibility of price retesting the upper resistance again in very short term.
