TALEB'S BARBELL STRATEGY
1. 85% to 90% of portfolios in safe instruments and the remaining 10% to 15% in highly speculative bets such as options.

2. "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.
