STEM , EXAS , SPX updates.

For starters a new one I'm peaking at, looking in to.  Not that I'll probably look deep or long unless the chart gets more compelling, but it had some high volume green action on some trial results. 

Hype or do they have something finally? Someone let me know ;)

Now on to exas.  Disclosure, yes I still own it of course.  And have no plans to the contrary.  Why even post the chart.  Yeah no point.

SPX update.  Just to show the lines vs the price, nothing changed but the sands of time;

Coal stocks have rallied but 52 week lows are fresh, and unless I'm missing some "big bottom", I can't trust any of them to be able to sustain upwards appreciation . . .
