At least my children now know a little more about the octopus species. OK So much for that……
Now, I knew the following would come comparing the Octopus to Investment/Bank experts …And here we go at a cnbc story… UBS, for example, gave Spain just a 4 percent chance of winning the trophy with their past performance model. The Netherlands, who meet Spain in the final Sunday, had just an 8 percent chance, the bank said. And our dear expert – Paul has nearly been flawless – o to say – …..

Somehow , Brought to my mind the famous orangutan coin flipping competition.
In 1984 Columbia Business School hosted a celebration of the fiftieth anniversary of Graham and Dodd’s book Security Analysis. The two principal speakers were Rochester’s Michael Jensen, an academic who had come out strongly in favour of the Efficient Market Hypothesis and Warren Buffett. Jensen stated that it was hard to tell if any of the followers of Graham and Dodd were really superior investors. He argued:
If I survey a field of untalented analysts all of whom are doing nothing but Flipping coins, I expect to see some who have tossed two heads in a row and even some who have tossed ten heads in a row.
This was a perfect entry for Buffett who envisaged a national coin-tossing contest. Each day, everyone in the United Sates flipped a coin with only those who continually flipped heads staying in the contest. After twenty days only around 215 flippers would remain. Buffett continued (Buffett, 1984):
But then some business school professor will probably be rude enough to bring up the fact that if 225 million orangutans had engaged in a similar exercise, the results would be much the same—215 egotistical orangutans with 20 straight winning flips.
Buffett then argued that there were important differences. What if, for example, all the orangutans came from the same zoo? When you replace head-flippers with “superinvestors”, he argued that this is precisely what happened. Buffett declared that there was an unusually high concentration of successful coin flippers, that is, “superinvestors”, in the investment world that “came from a very small intellectual village that could be called Graham-and-Doddsville”.
