I've been thinking about this same concept. It rings similar to what Nassim Taleb describes as his "Barbell" approach.
For instance having ~95% of the portfolio in 'safe' yield based investments like T bills/notes or highly rated corporates (it doesn't specifically matter for this explanation) such that you generate a 'base' yield on the portfolio , say 3% (relative to the total equity value of the portfolio), then using the remaining 5% of equity to make high risk high reward types of bets where your maximum loss is no more than 100% so that you can not possibly have a drawdown larger than the difference between your risky allocation of 5% of equity minus your 'base' portfolio income of 3%, of 2%.
The specific % allocations and whatnot could obviously be jiggered around but that's the idea. Is anybody here familiar with a strategy such as this?
