I am very bullish on DexCom mainly because they offer a system for Diabetes patients that is unbeatable right now (and I haven't seen Diabetes rates go down, rather the opposite).
It looks like the MACD is rounding back out for a crossover and the RSI is becoming oversold on the daily chart.
I'll be watching very closely and hopefully start to see a reversal around $250 where I will go long again. As of right now, I will be waiting...
