Neil Chriss is building something at Millennium. : It’s been about two months since Neil Chriss, founder of recently-defunct hedge fund Hutchin Hill Capital, announced his intention to partner with Millennium Management to build out a new quantitative trading business. The unit now has its own name, and Chriss is looking to add to his team. Dubbed Omnis Quantitative, the business is being described as a “Millennium platform company.” Chriss has already made at least one confirmed hire. Andrew Ronan, a former quantitative research analyst at Hutchin Hill, has reunited with his boss under the Millennium umbrella.
