Sell one junk and buy another junk. Both are junk. I own both AMD 4 K and BSX 5k and it has been very long time. My fault - never learned to sell. I was tempted to sell BSX when it crossed $12 and it behaved positively for a week and made me think that some good news may be coming on earning front and then this. Junk is a junk, never think junk will become gold.
