This is a joke right? ERX only contains 40.87 percent XLE as a holding. They are not the same thing, whereas USLV and SI are both just futures of the physical commodity. Why being so obtuse here?
Here's gold and it's 3x and inverse 3x for the last year
Here's silver and it's 3x and inverse 3x ETFs for the last year
Here's oil and it's 3x and inverse 3x funds YTD (they started trading more recently)
Do I need to go on? Can you present some examples of where the leveraged funds reflect exactly or even within a few percent of what you'd expect given their multiple of the underlying over a "hold" time period? Literally everyone has told you you're wrong, the onus is on you to prove your point my friend which you've gone into contortions to avoid while making a fool of yourself with your "mike drops".
In reality, you don't even need these examples. This is a simple reading comprehension and math problem. First, read a leveraged ETF prospectus. You've done that right, before pontificating on it. What, you've never read through one but you're passing these falsehoods anyway! Unbelievable. OK, well go ahead and read one now. Focus on the way they track
daily not total returns. Then build an Excel spreadsheet. Put in a random walk of the underlying in one column, the response of a 2 or 3 times margin futures account in the next, and the response of a 2X or 3X ETN doing
daily returns in the next. It will be clear even to someone as obtuse as you (that the correct use of that word, by the way), that they are in no way equivalent. Again, if you can even explain the concept of daily vs total returns to us and provide an example we'd be all ears, but so far you've been unable to do so because you don't actually understand it.
It could be that you're right despite never reading a prospectus or modeling prices or looking at a price chart of a leveraged fund vs its underlying. And all the people who have done all those things who disagree with you are wrong. Possible but highly unlikely. Just a tip for you going forward, when you're in this kind of position, stop, think, consider if all those other people might have a point, spend 5 minutes reading, modeling, and looking at historical price charts......and then respond. It will keep you from looking like such a fool.
And don't forget the first rule of holes. When you find yourself in one, stop digging!
