Portfolio management · Family offices

Multiply your returns with convex portfolios

Same market, different payoff shape. Carry when nothing moves, a floored downside, and an upside that accelerates: constructed, executed and stress-tested by the same engine.

Illustrative payoff shapes at the horizon shown. Not a forecast and not a record of results.

Earns flat

Carry comes from structure, not direction.

Floored downside

Worst case is capped by structure, priced before you own it.

Upside accelerates

Convexity compounds as the move extends.

The gap

You have the exposure. You do not have the desk.

Family offices carry the risk derivatives are built to solve, and rarely carry anyone who can price the solution. Open a card for what we do about it.

The stack

Three agent layers, in that order

The alpha is generated first. Execution and risk exist to protect it, not to substitute for it.

Generate the alpha. Price the universe against our own surface and rank what is genuinely mispriced.

Execution

Alpha leaks at the fill

Taking mid on a multi-leg structure costs you on entry and again on exit. Set the structure below and watch what working every leg is worth.

Broker quotes

Bid, ask, size behind each level, and how stale.

Underlying

Live movement between quote and fill.

Our fair value

An independent price, not the counterparty mark.

Decision

Work, reprice, or wait. Never chase.

Illustrative arithmetic on the structure set above: spread cost paid on entry and exit against the share our worked orders keep. Not a record of fills.

Risk

You see the downside before you own it

Every proposed book ships with a stress table: losses at the same weight as gains, on the same page. Set the size and the volatility regime.

Traceability

No black box

Deterministic models score, rank and size. Language models classify and explain. That boundary is why it survives your compliance review.

Authority

Who decides what, in writing

Your money never leaves your account, and you approve every position and every execution.

Capital stays with your own custodian. Permissions are trade-only, scoped to one dedicated account, and revocable by you at any moment. Flip the switch to read either side of the line.

You retain

Custody, approval and the right to stop everything at any moment stay with you.

What we can show you today

Two things, both labeled for what they are. Neither is an audited composite of managed client accounts.

Principal’s own capital

Existing options book

~25% gross · trailing 12 months

A multi-ticker book run on personal capital using the same engine, before fees and financing.

Proprietary capital, not managed client assets. Not audited or independently verified. Broker statements available under NDA on request.

Published, append only

Forward Test

WINS and LOSSES at equal weight

Every idea timestamped and published before the outcome is known. Nothing removed, nothing revised.

A hypothetical record of engine output. Does not reflect actual trading and does not account for execution costs or slippage.

Disclosure

What we are not

Stated up front, because your counsel will ask.

StockAgents is a technology provider. We are not registered as an investment adviser, portfolio manager or dealer in any jurisdiction, and nothing on this page is investment, legal or tax advice. Engagements are software and research services under written agreement.

Capital never moves to us. Your account stays at your own custodian, in your name, and any trade permission you grant is scoped to that account and revocable by you at any moment.

Figures on this page are illustrative model outputs or clearly labeled proprietary results. Options involve substantial risk, including losses greater than the capital committed, and past performance does not predict future results.

Bring us a position and we will show you the book

One holding or one constraint. You get a proposed structure, the pricing behind it, and the full stress table.
