I own 90% biotech stocks and in general I'm a longterm investor. I buy often stocks when they are less than a dollar and often sell them when they are 2-4 baggers. My motto for 2015: "Remember to take profit once in a while "!!
Let it roll :) Do not go for charts much. Random walk often with a (60-40,50-50) split on BULL/BEAR so a non believer I guess. I do think charts are useful but not the Indicators they are ALL coin-flips.
