LOOK AT DOW THEORY , THE FOURTH PRINCIPLE
"AVERAGES MUSTCONFIRM EACH OTHER"
HERE THE RUSSELL 2000 COULD NOT CONFIRM RISE OF S&P 500, WE HAVE A BEARISH NON CONFIRMATION, SO THE VALIDITY OF THE UPTREND CAME INTO QUESTION
ON 19 JAN RUSSELL 2000 MAKE A NEW REACTION LOW TWO DAYS LATER S&P 500 RECORDED A NEW REACTION LOW AND CONFIRMED A CHANGE OF PRIMARY TREND FROM BULLISH TO BEARISH ( WHEN PRICE CLOSED BELOW 4500)
