# Portfolios and strategies

> A shared allocation model with separate holdings for every subscriber.

## The model and the holdings

A **strategy** describes the assets a manager chooses and their target weights.
A **user portfolio** is the set of assets held in that user's smart account.
A **subscription** connects the user portfolio to the manager's strategy.

Many users can follow the same model.
Their account balances and positions remain separate.
They do not receive a token representing a claim on a pooled MyStacks fund.

## Target allocations

Target weights express how the manager wants a portfolio to be distributed.

For example, a strategy might allocate 50% to Asset A, 30% to Asset B, and 20% to Asset C.
These names and weights are illustrative.
They are not a supported asset list or an investment recommendation.

Prices and portfolio activity can move actual weights away from the target.
A rebalance trades assets to move the portfolio toward the intended allocation.

## Rebalance decisions

Managers save target weights and a recurring schedule through the [Manager API](/api-reference/overview).
Saving an allocation change does not start an immediate rebalance.
The planned execution workflow uses it at the next applicable schedule boundary.
The [schedule contract](/api-reference/stack-configuration#schedules) defines the accepted UTC presets.
Automated scheduled trading is still being built.

Each subscriber needs execution based on their own holdings.
A shared strategy does not mean every account can execute an identical trade amount.
See [execution and rebalancing](/architecture/execution) for the transaction flow.

## Asset coverage

MyStacks is focused on portfolios for tokenised finance.
The supported assets depend on the selected networks and available swap routes.
The Manager API accepts the [supported trading assets](/api-reference/assets) on Robinhood Chain.

Fee schedules and portfolio analytics also need dedicated documentation as those product details settle.
