Quote from 5yrtrader:
Ok, lets say you have convinced me that speculators are responsible for the oil price spike to $148.
So who was responsible for the fall from $148 to $32?
Speculative buyers covered their positions, left the market, and some went short.
The relationship between supply, demand and price, still holds. The distinction here is the motives of those buyers and sellers. Are they buying and selling the underlying to hedge future production or guarantee inventory? Or are they using the contract as a vehicle to realize speculative gains? If so, how much does that speculative volume contribute to demand? And therefore, price?
Another point to consider with bubbles is money flow. During the oil run-up, a huge amount of cash was siphoned off index futures and equity markets during their crash. The thing about bubbles is they suck in indigenous capital native to any one contract, but also from exogenous pools to fuel the run-up. Thats what Tulip Mania is all about.
