As everyone should know I am a great believer in luck playing an invisible hand in the success that many people enjoy. And there does come a time when you can spot luck deserting someone as the need for skill becomes apparent. The hedge fund Tiger Global has lost 66% of all investor gains accumulated since 2011. I would posit that since 2011 Tiger Globals’ management simply got lucky in riding an unprecedented technology boom. Now that this boom is over their lack of skill is on show for all to see.
