Look at the CBMX chart between late June and ealy August of this year. That's what you'll see again this time.
It had its spike to 4.47 and now it will set up again for a retest of that spike. Buy as much as possible below 2.80 and lower if it drifts down to lower prices. Volume was huge and WallStreet wise guys never miss a retest opportunity to profit big. 4+ is coming again sooner rather than later.
