The price of gold went haywire last week -- and sent Wall Street into a lather. Around about that time, Goldman Sachs (NYSE:GS) predicted the shiny metal would soon fall below $1,400 (sooner than they thought, as it turned out), though a Wall Street Journal columnist suggested there was method to gold's madness: that an ounce of gold should cost enough to buy 15 barrels of oil -- now, tomorrow, and always.

Problem is, the Journal was wrong about that. Fool contributor Rich Smith explains.
