Quote from Haroki:
Your assessment is a fair one about what's happening NOW.
That's cuz I think recent events - bull market - is skewing your memory/opinions.
If/once we get into a bear market again, you will be thinking that "FAS never gets back to its previous level if you hold long enough...."
The truth is, they BOTH degrade an equal amount over time, on a long enough timeline. It's just that the ETF that is in agreement with the dominant trend won't degrade as much and/or remain unnoticed on a shorter timeline.
I do mean NOW as you said. I don't know what will happen once the true baseline of the ETFs is descovered. I realize that baseline can change, but at least a neighborhood should be determinable once we are there for while. Once that happens, then I think it will be safe to make trades in either for swing trading. Right now FAS is the only safe swing trade, or even position trade, FAZ is only viable for day trades, or single overnight holds (including weekends) and hope you are right because it's not going to recover.
