Monkeys on a Typewriter

If you take an infinite number of fund managers or proprietary traders and make them trade all the stocks in the universe then there is a certainty that one of them will come out with an astronomical - equivalent of a say, 10,000% - return.

Well, we have deduced this fact or rather inferred it from a famous mathematical lemma called the Borel-Cantelli Lemma. This lemma says that if one puts an infinite number of monkeys in front of typewriters and lets them clap away then there is a certainty that one of them will come out with an exact version of Shakespeare's Hamlet.
