In FX Jpy is often viewed as a risk currency - Japan is seen as a nation of savers/investors and in trouble times they bring their money home i.e. buy Yen (whether this happens in real life is irrelevant - it’s what the market thinks that matters).
Likewise Gold is a safe haven in trouble times.
But Tom is right about US stocks - look at Friday past - reasonably positive statements from the US and China re their trade talks and see how the USD2000 responded.
XAU/USD was bought Friday but given how stocks performed would it be a good idea to buy Gold Monday?

Edit: notice that I was mentioning investors being bullish back on Wed using the sectors of S&P etf’s and then again Thurs - the USD2000
