Not an expert but the profile says the trust is based on a covered call strategy to deliver dividends. I'd say it would have little or no effect and would actually benefit from a slow decline in the price.
There are several articles proclaiming GGN as the best investment where an investor gets security in precious metals (gold, silver) and oil as well as a high STABLE income source.
I have been looking for monthly funds which pay the same amount of dividend and most use a formula to adjust their dividend payouts. GGN has been .14 cents a month since its inception. This is a winner. Investors are blind to the fact that ZSTN gives an income which can be counted on every month, the same amount. I know what Im receving. Buy, buy, buy.
