The graph below plots the Dow 30 (the green line), as well as the level of the Dow relative to current-dollar GDP (the blue dots), from before the tech bubble through the mild recession that followed, the credit bubble, and our current recession. (The red dots mark the beginning and end of recessions.)
DJIA moves realtime, but yearly GDP is not known until well after the year end. I wonder how the graph is constructed.
1968年一两黄金值270港元,而以1970年本港楼价每呎110元(1968年香港暴动,因此不应以当年楼价计,故以1970年香港经济开始复苏那年的楼价计),即一两金换两呎楼。到1980年1月每两黄金值4800元,当年太古城住宅楼价平均每呎1200元,即一两黄金可换四呎太古城住宅,证明1980年1月金价太贵。到2000年1月每两黄金值2600元,太古城每呎楼价8000元,即一呎楼可换三两金,证明2000年金价太便宜矣。到今天,一两黄金值11000元,太古城住宅楼价平均每呎8000元,如以过去住宅楼价与金价关系看,金价上升空间还有多少
