Abstract: The zeroth stable $\mathbb A^1$-homotopy group of a smooth projective variety is computed. This group is identified with the group of oriented zero-cycles on the variety. The proof heavily exploits properties of strictly homotopy invariant sheaves.

Key words and phrases: $\mathbb A^1$-homotopy, oriented cycles, motives.
