The gold price has risen every year since 2001 from its low of around $250. From then until November 2010 the gold price has risen to over $1400, a cumulative rise of 460%. Five of the years between 2002 and 2010 were marked by annual gains of 20% or more.
In today’s market, trading in several exchanges of both physical gold and gold derivatives determines the daily gold price, with the traditional London gold price fix still serving as the daily benchmark price. This fix is set twice daily at 10am and 3pm. The price of gold is usually measured in US dollars per troy ounce.
