What is your current recommendation on the percentage of gold and silver that investors should have in a portfolio?
Jeff Christian: In the early 1980's, there was some seminal research gold prices had been freed in 1968 to float under L.B.J. and then Nixon closed the gold window, the official Central Bank gold window in 1971, and gold prices were allowed to float even more, and then we had U.S. ownership in 1975. There's some seminal work that showed that 5% or 10% of your portfolio, optimally could have been in gold from 1968 to 1980. We've re-ran those numbers last year and said what about 1968 to 2015, 2016 and we found that if you took a portfolio of 50% S&P and 50% T-bills and you added gold to it in 5% increments, the optimal gold allocation was actually about 27%-30%, depending on whether you used T-bills or T-bonds. So, 27%-30% was your optimal amount of your portfolio in gold, or gold and silver, over the last period from 1968 to 2015. Going forward, given the greater uncertainties that we're facing in the financial markets: the stock market, currency market, interest rates, it's probably going to even be a higher percentage, but again, this goes back to what I was saying earlier. You have the vast majority of gold investors actually being college educated, wealthy people, who understand this stuff. They don't buy gold because they think the world's going to end. They might buy gold because the world might end, but more importantly they buy gold because they understand that having a portion of your wealth denominated in gold is better than not and having a portion of your investment portfolio in gold assets is much better than not having gold as part of a diversified portfolio.
