Price=grade=falling Hemlines?

I was reading last night how some of the stockmarket people have watched hemlines as an indicator of the stockmarket. Rising hemlines meant the stockmarket would rise and falling hemlines meant it would fall or so the theory went. I guess stock prices discounted into the hereafter, as they are today, is being mimiced by thongs

But the idea with hemlines was/is that there are bountries--the thighs and the floor. So when they have risen as far as they can go, as they did in 60's, then they have to go down and so too, supposedly, would the stock market. This did actually happen in 60's. I don't believe that it was the case in the 20's. The stockmarket crashed in 1929 but the hemline was only just above the knee. But then again compared to 1920, just flashing a shinbone was pretty radical.

I was wondering if there might not be a similar anology here with the previous discussions on 100 point grading. Was this an attempt to "raise the hemline"? And what about the result? Seems to me they got a resounding "bite-me" from the numismatic community. Might that be interpretated as major price resistance?
