While fear may from time to time play a role in creating price spikes in gold, the underlying bull market has been driven by solid fundamentals. Those who have been too afraid to buy simply do not understand the underlying dynamics and have instead decided that the market is irrational. As a result, gold continues to climb the classic wall of worry as any dip in its otherwise upward trajectory causes the speculative investors to jump ship. And that typically turns out to be a big mistake.
