Problem
Retail investors who want to own high‑priced stocks or ETFs often cannot afford to purchase whole shares, limiting their ability to diversify or invest with small capital. Traditional brokerages may also require higher minimum balances or lack a streamlined mobile experience for fractional trading.
Solution
Adelphi operates a self‑clearing brokerage platform that lets users buy and sell fractional portions of individual stocks and exchange‑traded funds through a mobile app. The platform handles trade execution, settlement, and custody internally, eliminating the need for a third‑party clearing firm. Users can create and manage small‑scale positions without receiving investment advice, and all accounts are protected by SIPC coverage up to $500,000 (including $250,000 in cash). The service emphasizes an educational, informational approach, placing full decision‑making responsibility on the investor.
Target Audience
Adelphi targets individual U.S. investors who prefer to allocate modest funds across a diversified set of stocks and ETFs, particularly those seeking a mobile solution for fractional ownership.
