The three-year chart illustrates a stock that has moved higher as it broke out of a tight range bound trading pattern. For most of 2013 the shares oscillated between support at $3.25 and resistance at $3.75. In March of 2014 RTK broke above resistance and ran to a 52-week high of $4.49. The MACD and the RSI signalled a buy in November of 2013 that was the beginning of a new advance. What is also observable is the support along the uptrend line and along the 50-day moving average.
