# Single-asset simplification

Single-asset simplification is how a strategy that holds exactly one instrument skips allocation altogether: with a single holding there is nothing to weight against, so all of the strategy's invested capital goes to that one instrument. Allocation only becomes a real choice once there are two or more things to split capital between.

**Also seen as:** trivial allocation, "nothing to allocate"

## Why does a one-instrument strategy skip allocation?

An [allocation method](/docs/strategies/allocation-and-allocation-method) answers "how much of each?", and with one instrument the answer is fixed before you start. The app says so directly: where the method picker would be, the Allocation surface shows "Nothing to allocate yet", explained as "With one instrument and no Risk-Off split, 100% of capital goes to that instrument. Add more instruments or enable a Risk-Off split to make allocation meaningful." The **Single instrument** strategy type takes the same shortcut in the walk-through, which runs only Asset selection and Review — see [choosing a strategy type](/docs/strategies/choosing-a-strategy-type).

## When does allocation matter again for one instrument?

Two things bring it back. Enabling a Risk-Off split makes allocation meaningful even with a single holding, because Risk-On and Risk-Off are separate profiles and the Risk-Off profile needs a method of its own — see [risk conditions](/docs/strategies/risk-conditions). Separately, **sizing** is never skipped: the **Leverage** control ("Multiplier on position sizes. 1.00 = no leverage. Range 0.00 – 2.00.") still applies, because how much exposure to take is a different question from how to split it.

## Defaults in Fincanva

- With exactly one instrument and no Risk-Off split, the allocation method picker and the per-method weighting controls are not shown — the weight is fixed at 100% of the invested capital — see [invested portion](/docs/backtesting/invested-portion) for what that share is and what stays in cash.
- Adding a second instrument, or enabling a Risk-Off split, restores the full allocation surface.
- Sizing stays available in the one-instrument case: leverage scales the position, it does not weight it against anything.

## Worked example

You build a **Single instrument** strategy on one equity ETP. The walk-through never asks for a weighting method, and the editor shows "Nothing to allocate yet" where the picker would be — the instrument holds 100% of the invested capital by construction, and [weight drift](/docs/backtesting/weight-drift) has nothing to drift against. You then add a second ETP: the method picker appears, and the strategy now needs a rule to decide the split. Nothing about the first version was incomplete — there was only ever one possible answer.
