Mariposa Capital Management

Mariposa Capital Management

Edwin Choi founded Mariposa Capital after serving as a Director at Merrill Lynch, where he managed proprietary structured-credit portfolios. The Los Angeles-based firm operates as a fee-only investment advisor, earning its compensation directly from clients rather than from product commissions. Its stated mission is to deliver an evidence-based, institutional-caliber approach to individuals and families. Mariposa constructs portfolios across US and non-US equities, real estate, and commodities using only passive vehicles — index funds and ETFs — on the premise that active managers rarely beat benchmarks persistently. The firm layers tactical tilts based on value and momentum signals that it argues are supported by academic and industry research. It manages concentrated equity positions, restricted stock, and liquidity events such as business sales. The firm is structured as a boutique advisory without disclosed AUM, partnership structure, or co-investment vehicles. Edwin Choi holds both the CFA and CFP designations and runs the practice from a single office in downtown Los Angeles. The website provides a contact form and phone number for prospective clients but publishes no information about additional team members, external limited partners, or affiliated entities. Mariposa’s operational architecture distinguishes it from asset-gathering RIAs: the firm charges clients solely through transparent advisory fees and builds goal-specific glide paths that transition from aggressive to conservative allocations as financial needs approach. That structure aligns the firm’s incentives with portfolio durability rather than product distribution.
