Agreed, Latane, NWBO is tracking just like CYDY except with about a 3 month lag. I just bought into NWBO yesterday...so today's tanking is on me, I always, ALWAYS, seem to buy just before a fall.
I assume you're in NWBO as well? CYDY is far and away my biggest holding, I got into NWBO and NEXCF for a little diversity. Because, of course, diversity is our strength. Though if NWBO and CYDY get any stronger, my portfolio will look more like a crash site.
Long on NWBO and CYDY, stay off the auto-land/auto-throttle and good luck!
