As the Dow Jones Index increased from a low of 7,500 in 2002 to over 14,000 in 2007, its trading volume doubled. However, now we see a troubling sign. As the Index increased from 8,000 in early 2009 to over 18,000 in 2015, its trading volume is currently 2+ times lower. On the other hand, trading volume for silver continues to increase from its low in 2009…. even at a lower price.
