Looks like today really extinguished any hope left, not just for CDU but for many stocks. CDU has failed all its fib levels and today fell through it's uptrend line that had been quite strong previously.
Early signs were there with a succession of lower highs in October, November and early January. Each of the fib levels did provide brief support but couldn't withstand the weight of the general market since mid-Jan.
Today gapped down which might attract a short term rally to fill the gap. The $2.40 line looks strong support (if it gets there). (I actually traded CDU for a loss, got in at $4.80 and stopped out at $4.70, realizing that 38.2% fib line was history).
