"Ten million portfolios containing stocks randomly selected as if by monkeys managed to produce better profits than a tracker fund over 40 years, academic research has concluded."
"The average hedge fund has produced a worse investment performance in the first half of this year than a portfolio consisting of a savings account at your local bank and a random collection of stocks picked by a blindfolded monkey."
Don't have the source, but there was also a study with a cat throwing a dead mouse on stocks, who did better than professional traders :D.
Moral of the story: If someone tells you that they know the future, don't believe them. They are full of shit.
Cats and mouses? This is getting better and better ahahahaha
I laughed so hard with these. indeed gems @alexgr
