Here is a quote from the current issue of Barrons, which came out last Saturday...

"Adrian Ash, director of research at BullionVault...points out that over the past 50 years, silver and gold prices have gone in the same direction on 71% of all trading days and the two metals have moved in the same direction in 74% of the months since 1968." (Barrons, 3/5/18, pg. M11 "Silver Could Outshine Gold This Year")

Yeah I would agree with that if I read it correctly. When days Gold goes up silver does too and vice versa

What would be more in depth in at what rates they go up in correlation on most trading days. I see some days gold will go up 1% and silver go up 3%. So its at what rates where the trades would make sense

I've heard it said that silver often outperforms gold 2:1 or sometimes even 3:1 when they are going up, but underperforms it in similar fashion when they are both going down. Don't have any scientific evidence on that one, but it does sound credible to me. It is probably similar to comparing small cap stocks to large caps.
