  We use the Landauer-B\"uttiker scattering theory for electronic transport to
calculate the current cross-correlations in a voltage-biased three-terminal
junction with all superconducting leads. At low bias voltage, when charge
transport is due to coherent multiple Andreev reflections, we find large
cross-correlations compared with their normal-state value. Furthermore,
depending on the parameters that characterize the properties of the scattering
region between the leads, the cross-correlations can reverse their sign with
respect to the case of non-interacting fermionic systems.
