It IS easy, if you look at it right, AND you don't HAVE to sell at any particular time. I view the GSR as a big rubber band. The more you stretch it toward 100 the tighter it becomes and the more likely it will snap back at some point. If you realize silver is a bargain when GSR is very high all you need to do is keep stacking. When and if the GSR dives and/or silver takes off, all you have to do is either decide whether you want to sell some of your silver outright or trade it for gold.
I need to step up and pull the trigger on a few ounces....back in my first buys I didnt understand the ratio and bought $1000 in Ag when the it was 39:1....stupid stupid stupid...I needed to take advantage of this opportunity to correct that mistake....but I like my gold...and as Irons says "it is too hard to come buy to just trade"...lol....I got raisins for testicles right now.
I don't know, we are getting into some pretty rarefied air. The following chart shows the GSR since the gold window closed in 1971. You can see that, other than the early 1990s when it farted around at 91 for awhile and had one brief spike to 100, this is as high as it has been.
