A good question and good comments from Jacques and Simjojim (both of whom I usually disagree with).
I have been thinking about this for a few weeks and the cynic in me thinks that after the knee jerk reaction to the result, nothing much will change and gold and silver will continue to trend higher on the back of inflation expectation related to supply constraints in key staples (mainly energy and food).
The wild card would be a Republican victory and an implementation of the Paul Ryan plan.
The resulting deficit blow out would test what is really driving precious metals: concerns over debt and monetary expansion (which I always questioned) or the direction of risk assets (which has been a theme of my comments for the past year).
One way or other, I expect volatility to increase. This tends to weigh heavily on precious metal prices because of the increases in collateral requirements and market risk capitals for banks and institutional traders.
