A new method to search for moving groups, specifically tailored for the HIPPARCOS database, is used to search for moving groups among the high velocity stars in this database. Although the sampled volume is small, the high quality of the astrometry makes this search interesting. No moving groups are detected, but limits in the velocity and number of members of possible non-detected groups are given.
