Porter Stansberry spent 30 years ignoring outside investment systems - until he met Emmet Savage in Dublin. Savage's model, built on Hamiltonian mechanics applied to equity analysis, has delivered nearly 2,000% returns over 17 years with only one losing year.

What convinced Porter wasn't the returns. It was the sell discipline - a framework that identifies the exact moment a position's energy begins to decay, signaling an exit before the decline. He calls it the most rigorous sell system he has ever seen, comparing its edge to RenTech's famed Medallion Fund.
