Solutions
Two ways to work with Libra. Two complementary investment components. Clients may choose a managed account held in their own name or, when eligible, an investment note issued by an independent third party. Depending on the mandate and legal structure, Libra may combine a strategic public-markets component with a systematic futures component.
Segregated managed accounts
A brokerage account opened in the client's name at an approved third-party custodian. The custodian holds the assets, processes deposits and withdrawals, and provides account statements. Under a written advisory agreement, Libra receives limited authority to trade only within the agreed mandate; the client retains ownership and control of the account.
Third-party-issued investment notes
A security issued by an independent third party that gives an eligible investor exposure to a Libra-managed strategy. Where permitted and supported by the investor's financial institution, the note may be purchased and held through an existing bank or investment account. The investor owns the note, not the issuer's underlying portfolio account, and is exposed to the issuer and the risks stated in the offering documents. Libra acts as portfolio manager and is not the issuer, custodian or guarantor.
Strategic public markets
The portfolio's long-term core is built primarily with U.S.-listed ETFs and selected U.S. equities, with fixed-income instruments and cash used where appropriate. Public filings and manager holdings may inform the research, but Libra evaluates every position independently. Selection considers the position's intended role, liquidity, cost and contribution to total portfolio risk.
Systematic futures
Rules-based models may take long or short positions in highly liquid, exchange-traded futures, focused primarily on U.S. equity indices, U.S. Treasury and interest-rate markets, and selected currencies. Entry, exit, position sizing, leverage, concentration, margin and drawdown limits follow documented controls. The strategy may also reduce exposure when conditions do not support a position.
Securities and futures advisory
Libra's investment-adviser registration covers securities advisory services. Its commodity trading advisor registration covers advice involving commodity interests, including futures. The applicable agreement determines which services and instruments a client receives.
Risk defined before implementation
Objectives, risk tolerance, liquidity needs, eligible instruments, restrictions and reporting expectations are documented before the portfolio is implemented.
Independent custody
In a segregated account, assets remain in the client's name at a qualified third-party custodian. The custodian maintains the account, handles cash movements and sends statements directly to the client; Libra's authority is limited to the written mandate and account permissions.
Systematic infrastructure
Technology supports data collection, quantitative research, statistical validation, portfolio construction, implementation monitoring and risk controls through a documented, repeatable process. Technology does not eliminate investment risk.
