Our track record is public, and hence there is total transparency within our organization with respect to that.I hope, of course, that our team members are able to outperform our previous track record.I do not personally engage in much manual or discretionary trading — most of our strategies are either fully automated or traded by someone other than myself. I have even delegated most research work to our staff, but with my overall direction and close supervision.

As the CIO, my main job is capital and resource allocation across different traders/PMs, and to manage risk on daily basis.

As the CEO, I make regular but less frequent hiring and firing decisions with regard to our PM’s and researchers. I perform the necessary due diligence when hiring, and ongoing monitoring and reassessment of existing hires.

I also provide directions and suggestions with varying amount of details to our researchers (depending on their level of experience) as they create new strategies or improve old ones.

My CTO provides all technical support for our trading operation, and we outsource most accounting, reporting, and regulatory compliance tasks.

Financial metrics such as Calmar ratio are the most important determinant of our allocation decisions. They are made on a monthly basis.

Regarding researchers retention and promotion, creativity, technical know-how, grit/diligence, and communication skills are the most important determinants.Before we hire new researchers, we assess them according to these dimensions by having them work on projects as interns.

As our team work remotely, weekly video calls are absolutely necessary. Financial incentive is ultimately necessary, but not sufficient. The project has to be interesting and challenging to the researchers. They must feel that they are learning on the job, expanding their competence.

As a well-known and highly regarded educator, my team members find my training to be the best motivator. There were, of course, burnouts, stresses, personal issues, etc. in the past. But as my management skills mature, I have found ways to reduce the negative impact of these emotions by reallocating work-load among various workers.

As a large part of the compensation to top performers is based on profit-sharing, and there are industry standards for determining the share %, this isn’t hard.

Key Lessons from Ernie:

  • Financial incentive is necessary but not sufficient. In order for your team to remain satisfied and loyal, money is only a part of the equation. The challenge, capability to grow and the feeling of being part of a winning team are also essential;
  • There are several required key skills for team members — both for hiring new ones and assessing the existing ones. In his team, Ernie values creativity, technical know-how, grit/diligence, and communication skills. All of these are different skills, but that ultimately combine to make a great team player;
  • Clear separation of roles. From Ernie’s answer on balancing the CEO and CIO roles, we can see that he has split the roles into very specific tasks to take care of with different periodicity. This detailed division of roles allows for better planning and execution of your weekly calendar, more concentration and efficiency;
