| | Dean and Sam - I confess to being lost. I understand that t might not be worth your while to give me a primer course. But I wonder who else is (and is not) on track here.
I thought that I understood index funds, but clearly, I do not. So, I went back to the beginning with Wikipedia articles about the NYSE Index and working my way back.
Relevant to your exchanges here (I think), I found this:
"Some index ETFs invest 100% of their assets proportionately in the securities underlying an index, a manner of investing called "replication". Other index ETFs use "representative sampling", investing 80% to 95% of their assets in the securities of an underlying index and investing the remaining 5% to 20% of their assets in other holdings, such as futures, option and swap contracts, and securities not in the underlying index, that the fund's adviser believes will help the ETF to achieve its investment objective. For index ETFs that invest in indexes with thousands of underlying securities, some index ETFs employ "aggressive sampling" and invest in only a tiny percentage of the underlying securities "Some index ETFs, known as leveraged ETFs or inverse ETFs, use investments in derivatives to seek a return that corresponds to a multiple of, or the inverse (opposite) of, the daily performance of the index." http://en.wikipedia.org/wiki/Exchange-traded_fund
I understand that if the ETF has a transparent (known) market basket of stocks (or whatever), the ETF would sell for only exactly the value of the basket. However, EFTs offer certain marginal advantages, (especially regarding tax laws) because by buying and selling the Index, you are not actually trading in the stocks themselves, making many trades. Being traded continuously throughout the day, the price of the EFT will rise and fall a little bit versus the actual basket. I get that (I think).
But, given the quote above, I see Sam's point. As this becomes more abstracted, it matters little what the stocks actually do. As long as the Exchange makes good on bets, the numbers become abstractions.
To think of it in simple terms, right now the DJIA is at 12,084. Wanna pick a number for tomorrow's close? (To me, it looks like it's going down, but I don't think it will drop to 11,900. Moreover, I believe that it will not rise above 12,200.) If I am the house, I can take all bets. All I need is a "commission" (charge to you to place the bet), or a large enough pool that I am between the winners and losers. This is no different than betting on football: you have no control over the game - but you have a prediction into which you are willing to invest.
Commodities futures - and derivatives of them - are a similar abstraction. Fundamentally, there is "stuff" behind the trades, gold soybeans, whatever, but no one really cares. The derivative is the product. So, Sam's Virtual EFT has potential.
(If I am so far off that response is painful, just say so. Thanks.)
Dean: As soon as the Fed stopped pegging USD to gold and silver, USD's value floated away from the price of gold and people stopped trading it for its declared value. Sam: Yes, because gold has value independent of the $US. Sam
But the Hong Kong Dollar and Caribbean Dollar do not. They are pegged to the dollar by the local central (government) banks which will buy or sell USDs to keep the official rate. Even so, the rates fluctuate - and they allow that without intervention up to a point - because of demand from people who need the local currencies, tourists if no one else. I have bought and sold currencies at the airports - convenience, not investment - and if the central banks did not "intervene" others would still be there to buy and sell into the demands.
