The barbell strategy is a method that attempts to secure the best of both worlds. It’s possible, the thinking goes, to garner substantial payouts without taking on undue risk. The strategy’s prime directive is interesting in that it’s not only counterintuitive to a populace weaned on the benefits of tempering risk and reward, it’s unambiguous: Stay as far from the middle as possible. 

Nassim Nicholas Taleb [...] phrases the barbell strategy’s underlying principle as follows:

"If you know that you are vulnerable to prediction errors, and […] accept that most “risk measures” are flawed, then your strategy is to be as hyperconservative and hyperaggressive as you can be instead of being mildly aggressive or conservative."
