The trend lines drawn on the chart show the downtrend of Twitter over the last year and its upswing since May 2014. Having come down off its recent spike, it resumes its downtrend. It remains to be seen if it will have a little spike before its results on 29 July. I guess that spike has already happened and run out of steam. To reverse the downtrend, the company will have to show that profitabiity is imminent.
