L'économiste Joetta Forsyth à propos des bienfaits de la spéculation:

"Speculators anticipate shortages and buy up commodities early, thereby removing them from the market. This alerts consumers to the oncoming shortage, fulfilling the important financial market role of providing information and allowing them to reduce consumption as prices rise. Later, the speculator sells, ameliorating the shortage while making a profit.

Speculators anticipate and warn others about shortages—they do not cause shortages. As a result of their trades, price swings are less severe than they otherwise would have been. We do not blame doctors, police, or firemen for profiting from the misfortune of others because it is understood that they help a bad situation. Speculators deserve the same consideration."
