Sorry, I don’t buy it (no pun intended). In my opinion, the risk in waiting for gold to go down to the mid 500’s is bigger than the risk in acquiring at least a partial position now, and then buying more on the dip if it occurs. The move above the 200 dma can also be corrected by the moving average coming up, not only by the price going down.
But of course it’s your money, so you have to make the decision. Just remember that these advisors can be wrong too, and they won’t help you if you get “priced out”.
