This is a pretty straight forward trade. The daily Transportation Index ETF $IYT jumped from $173 to $187 in three days. First, this makes it overbought for a swing trade short. Then you note the major trend line price hit today that stretches back to 2015 and the multiple technical indicators screaming overbought. Lastly, add in that this run is factoring in tax reform, which means there will be little further risk even if tax reform gets through (which is likely). This is a solid risk/reward swing trade short. I would like to see a pull back minimally to $168.00.
