ESTR starting on a strong uptrend in 2019, breaking out of downward channel lasting for the most part of last year.
The fundamental driver likely an anticipated strong earnings report for 2018. According to Morninstar, Price/Cash Flow decreased from 137.83 in 2017 to 1.31 in 2018.
Number of shorted shares decreased around 10% YTD, and is below 1% of float currently. Short interest is steadily decreasing from a high of 10% to around 8% YTD.
A short term 50-100% price target is not unrealistic. Watch for support on 20 day MA. Stop loss should be just below 50 day and 20 day MA lines.
