It's Zacks, not "Zack's", and they haven't been critical of VNR AT ALL. They've been pumping VNR for months. I see nothing new from Zacks since 6/24, over two weeks ago. And VNR is DOWN 1.5% as I type this, while WTI is UP 1.7%.
It doesn't have anything to do with "18K". The VXX is indexed to the VIX, the implied volatility of S&P 500 index options. Nothing to do with the DOW. Considering all the comments you make, it's amazing you don't even know what the VXX or VIX is.
