Not Your Father’s Broker
Mariposa Capital Management is an investment advisor to individuals looking for a different kind of advisor. Our approach to investing is to use simple yet effective strategies that are based on research and empirical data.
Why Our Clients Choose Us
Fee Only, No Commissions. Our compensation is fee only, paid directly and transparently by clients. Unlike most, we do not earn commissions or have any hidden financial incentives. Commissions can give advisors an incentive to recommend the very strategies you should be avoiding: trading frequently and buying investments with high expenses.
Emphasis on Research and Empirical Data. Anyone can come up with investment strategies that sound great at first but fail the test of evidence. We only recommend strategies that are actually supported by research and empirical data, not what happens to be popular on CNBC. In fact, we use these same strategies in our personal portfolios.

Mariposa was founded by Edwin Choi, who, after many years as a portfolio manager with Merrill Lynch in New York, decided to bring institutional-level investing to individual investors. Edwin is a CFA (Chartered Financial Analyst) charterholder and has passed the CFP (Certified Financial Planner) exam.
