US Stocks reached their peak in 1999, and have clearly been in a bear market since 2001. From a high of 1400, they have fallen to the 280-290 level, a drop of 80%.
From 2003 through 2007, stocks appeared to perform well when priced in dollars, roughly doubling in value. Because virtually all of this gain was due to depreciation of the dollar, however, the gold price of the stocks actually declined slightly over the same period. During 2008 and early 2009, stocks gave up all of their gains since 2003 when measured in dollars. Priced in gold, they declined from about 800 grams to 220 grams, a 70% loss from 2003 levels.
Since the bottom in March of 2009, prices have risen strongly when measured in dollars, seen by many as proof that the recession is over and recovery has begun to take hold. Yet when priced in gold, we see that all of the "robust recovery" was the result of more dollar debasement, as trillions of dollars created by the Fed's "quantitative easing" and bailout programs flood into the market. In reality (aka priced in gold), stock prices have remained fairly flat from 2009 until July of 2011, when they began falling to levels well below their 2009 lows. Since then, they have been slowly recovering, and appear to have peaked in 2015, about where they ended 2008.
