The Chart of the Day notes:
"Gold has been in a strong bull market since 2001 and picked up the pace in mid-2005 and then again in mid-2007. In fact, gold has gone parabolic and today briefly crossed the $1000 per ounce level for the first time. Today's chart illustrates how the price of gold has nearly quadrupled during its seven year bull market."
