# BasketConcentrationCapExceeded (/docs/errors/chain/BasketConcentrationCapExceeded)

The `swap_basket` buy would leave the destination holding above the `BasketConcentrationCap` share of fund NAV (holdings marked at realizable value; the cap is u16-normalized, so 4096 means 1/16). Buy less, or spread the fund across more holdings — at the 1/16 cap a traded fund needs at least 16. Query `BasketConcentrationCap` for the live cap. Not enforced while the chain has fewer subnets than the cap demands.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`limit_exceeded`](/docs/errors/limit-exceeded).

Declared at [`pallets/subtensor/src/macros/errors.rs#L372`](/code/pallets/subtensor/src/macros/errors.rs#L372).
