I sold all my considerable holdings in $CONY $NFLY and $ULTY. I had owned most shares 12+ months so made enough divvys to break even. All were in IRAs so not subject to tax. Yesterday. Transaction was a loss at least from the NAV perspective.
Pretty sure I will be watching these in the future to validate my sell decision. So far, I'm not sorry in the least.
I would not be shocked to see shareholders taking legal action against YM. Meanwhile I am not buying any ETF that ends with Y. It's just that simple.
