An investment Book is a living, parameterised portfolio: a declared policy — universe, selection, sizing, constraints, holding rules, rebalancing, execution and risk — applied continuously to fresh forecasts, with every position, outcome and change recorded against that policy.
Why it matters
A model portfolio shows what was held; a Book also shows why. Because every decision traces to a parameter, a result can be attributed to the forecast, the sizing rule or the risk limit that produced it — and changed on evidence rather than on mood.
How it works
A template carries the policy; a Book is an instance of it with its own mandate. Each day the Book reads the latest forecasts, applies its selection and sizing rules within its constraints, and records the positions and results.
How Opulence Alpha applies it
Opulence Alpha's reference Books (Growth, Moderate and Conservative) and the Golden Ticket benchmark baskets are all Books built from policies. The Golden Tickets differ from each other in one field only — the sizing method — so the gap between them measures that one decision.

Questions
Is a Book a fund?
- No. A Book is a portfolio run by software under a declared policy. Opulence Alpha is non-custodial and does not hold client assets.
What does a Book show that a portfolio does not?
- What it believes, why, how uncertain it is, the resulting positions and risks, the outcomes, and what changed afterwards.
Can two Books share the same forecasts?
- Yes, and that is the point: when they differ only in one policy field, the difference in their results measures that field.
Is a Book a systematic investment Book or a dynamic investment portfolio?
- Both. A Book is a quantitative portfolio system run by rules: quantitative portfolio construction from the forecasts, systematic portfolio construction under a declared policy, and quantitative portfolio management every trading day. It is a continuously tested investment strategy, measured in public on its own page.
How do Books allocate across horizons?
- Through multi-horizon portfolio allocation: positions blend the 5-, 21- and 63-day forecasts, each with its interval, and are sized by the model's conviction: probabilistic portfolio management rather than one point estimate. Quantitative asset allocation then stays inside the Book's position cap, gross exposure target and risk limits.
