The London Bullion Market Association ceased publishing daily data on their Gold Forward Offered Rate (GOFO), as of 30 January 2015 -- so we develop an observable proxy called tango.
During 2015 we detected strong negative correlation between price change and tango, however, in 2016 that strong correlation became positive -- thus we conclude the relationship is spurious. The observed correlations are mere artifacts which do not imply any significant economic relationships.

Polished https://git.io/gdpspx -- We examine the US gross domestic product's relationship to the US equity market (S&P500), in real terms. Forecasts for both are demonstrated using Holt-Winters time-series model. We derive the most likely range for real GDP growth, and identify extreme equity valuations aside from inflationary pressures.
Our analysis would suggest the following back of the envelope calculation: say, SPX nominally has an annual gain of 6% and inflation stands at 2%, then the real SPX gain is 4%. Take half of that to arrive at real GDP growth: 2%. Helpful because GDP numbers are announced after months of lag.
