LAST EDITED ON Jun-10-08 AT 10:29AM (MST)[p]The answer is "All of the above" Manny...... Speculators and supply & demand are both playing a role.
Bottom line in a free market though is ALWAYS supply vs. demand. As long as there is high demand, the prices will continue in kind. When the market reaches a breaking point (whether it be due to speculators, gas guzzling consumers, or what-ever....), the price will stop rising. Simple economic theory will always rule in a free market.
