Listened to a commodity broker I was skiing with in early 1987. He was predicting a big market crash and noted that over crashes, hard commodities (e.g. gold) and related stocks generally did well. I moved significant money to gold mining stocks. They fell with everything else in the downturn in the fall of 1987, and never recovered. Sold them finally for about $0.15 or $0.20 on the dollar. Yeehaa!
