Kev… for example, the futures prices for gbp/usd spot and gbp/usd futures for the december exipration contract is about 2 pips different (futures are 2 pips cheaper)
So, this gives you an idea of what the projected value difference between the dec-2011 expiration contract, and current spot price is.
so, the idea is, as we grow closer to the third friday in december (futures expiration day), they will be the same value on that day.
you have to remember, nearly all value is priced in now…for what is expected later.
right now, aud/usd dec-2011 futures is about 25 pips lower than current aud/usd prices. But… if aud/usd moves up 99 pips this coming monday, you can expect the aud/usd futures to move up about 100 pips. this would bring the futures contract about 1 pip closer to the current spot contract.
and again, on expiration friday in decmber (3rd friday of he month), the price of spot and this futures contract will be exactly the same.
so, in this way, i guess you can say that aud/usd spot prices are expected to decrease over the next 6 -7 weeks… but only by a total of 25 pips…so…it may decrease about 1 pip a day lower than it would without the influence of the futures contract.
Keep in mind, that if we rip up a hypothetical 300 pips between now and then… you could speculate that the move SHOULD HAVE been valued at 325 pips…but that last 25 pips was the difference between future expected value and current price.
Basically man… u can get a vague idea of whether the general market thinks the price will be higher or lower in 3 months, 6 months, 1 year, 2 years…etc… but by the time that moment arrives, the overall change in price will nearly always be several orders of magnitude larger than the differnece in future expectations.
As in. if, for some crazy reason, aud/usd STOPPED TRADING COMPLETELY until the december expiration date in the futues contract. you could expect either the futures value to rise 25 pips…the spot value to drop 25 pips…or some combination thereof.
But the market DOES trade…fluctuations of over 100 pips a day is the norm, and with such fluctucations, trying to squeeze out a tiny 25 pip edge over 6 weeks is going to be a worthless appraoch. not to mention that it’s possibel that the futures values could INCREASE 25 pips.
I suppose you could go long 1 futures contract, and short 1 spot contract…hmm…now there’s an idea ;). but, you’d tie up a fair amount of capital to do so…and would have to wait about 7 weeks to cash out 25 pips. Still a potentially workable arbitration model…but, something tells me there are flaws i’m not seeing there… or else, as they say, its so easy, everyone would be doing it
food for thought…
