25 years on Wall St trading derivatives.

I traded derivatives on Wall Street for almost 25 years, most recently as a partner and a senior portfolio manager at a $14 billion hedge fund. For the past 11 years, I've also been trading options and managing my own portfolio. I've sized positions through quiet markets, broken ones, and the ones nobody saw coming — and every one of them taught the same lesson.

Risk first, invest second, options as an overlay third. That order matters more than anything else I've learned. Define Your Risk™ brings that same discipline to retail investors. Better tools, sharper thinking, and a framework you can actually use.

Risk first. Invest second. Options third — that order is the difference between trading and gambling.
