Simple correlations such as "MKT down, Gold Up" may not be very useful to traders and investors.
Trade price, not ideas.
Forget the last 20 years that Gold gave zero relief as safe haven when the market meltdown occurred, let's go back to the times that had no sophistcuted derivatives, and supposedly gold should have been safe haven.
The Tulip Bulb Panic from 1633 to 1637 had no effect on the price of gold. Gold prices were steady at £3.73 in London throughout this period.
During the years previous to and following the South Seas Bubble in 1720 gold prices were steady at £4.25; what had been proclaimed the gold standard in 1704 and remained-so essentially unchanged for the next three centuries.
The years preceding and following the Panic of 1792 saw steady gold prices at £4.25-standard levels.
The 1800s saw no less than a dozen named panics: gold in the United States rose briefly in 1865 preceding the Panic of 1866, but otherwise remained locked in a range between $19 and $23 for 130 years.
