Why “Callosum”? In your brain, the corpus callosum is the bridge between the left and right sides, so they work as one. Our two systems work the same way: one aims to grow money, the other aims to turn it into income, and over time gains from one can feed the other.

Who we are

Two clinicians who have been trading for over a decade.

Chris Cortez and Christopher Ashley have worked side by side for nearly 16 years as physician assistants in surgery, where preparation and attention to detail aren’t optional. They’ve traded for more than 13 years across stocks, bonds, options, commodities and crypto, and use AI every day, in the clinic and in the software behind Callosum.

Chris has traded the markets for 12 years, drawn by one idea: making money work for you, so you aren't trading your time for it. He has day traded, swing traded and invested long term across equities, bonds, cash, commodities and crypto. He has ridden bitcoin through 80% and 90% drawdowns to new highs, and lived through the Celsius and BlockFi bankruptcies, which taught him to put security and transparency first.

His approach starts with price action, which he sees as the leading signal, and with statistics and probabilities rather than lagging indicators, guesswork or gut feel. Day trading by hand didn't fit with a medical career and a family. So he and Christopher Ashley, friends for 16 years, built Nexus and Chronos Income together. Nexus is an automated futures system designed to pursue growth without costing you your time, and to reduce the emotional toll of trading. Chronos Income is designed to add monthly income you can use now. Most people focus on growth or income. Chris believes both matter equally for a balanced life that keeps moving forward, which is why the two systems are built to work together.

A practicing physician assistant in surgery and urgent care, Chris brings an operating-room standard to markets, where "good enough" isn't. His first rule is that risk management comes before profit, always. His own money is in every system he runs.

For Christopher Ashley, the goal was never simply to have more money. It was to have more say over his time—whether that's to play the drums, build something with his hands, or push himself physically to achieve new heights, and allow room for the things he loves.

For Christopher Ashley, the goal was never simply to have more money. It was to have more say over his time—whether that's to play the drums, build something with his hands, or push himself physically to achieve new heights, and allow room for the things he loves.

His fascination with saving and watching money grow began in childhood. After PA school, finally earning enough to invest, he turned that curiosity toward markets. More than a decade of learning brought losses, emotional highs and hard lessons: respect risk, keep learning and protect the ability to try again.

His surgical career reinforced the importance of preparation and adapting when conditions change. Alongside him was Chris Cortez, his PA-school classmate and longtime accountability partner. Their friendship grew through shared struggles, asking hard questions, mutual support and a bond to never stop improving—first in medicine, then in markets.

Together, they founded Callosum Capital Management with a purpose Chris holds close to his heart: helping people pursue greater autonomy over their time giving them more opportunity to do what fulfills them. Outside work, he finds that fulfillment in exercising, woodworking, and creating music, which allows him to constantly improve himself.

Our own money is in it. Nexus trades our own accounts, and Chronos Income is built from our own holdings. We run everything on ourselves first.
