Dolphins perform better at the stock market than market analysts do, a recent experiment at the Harderwijk Dolfinarium suggests. The animals got to pick five balls that represented companies. Five stock analysts got to pick five companies that they thought would do well in the market. After a year, the dolphins’ stock had increased 27% in value, but that of all but one of the analysts had decreased in value. The one analyst that made a profit only made 10%.
In previous years similar experiments were done with a gorilla, with similar results. The gorilla got to pick from a number of labelled bananas that represented companies, and made a profit of 15% above market index. Obligatory joke: they had to switch to dolphins because the gorilla kept eating the bananas.
