<i>Aims. <i/>We investigate and parameterize high proper motion red stars in the Torino Observatory Parallax Program.<i>Methods. <i/>Observations of 27 objects were made over the period 1994–2001 on the 1.05 m Torino telescope. The trigonometric parallaxes and proper motions were determined using standard techniques.<i>Results. <i/>We determine parallaxes and proper motions, and by comparison to models we infer masses, ages, and metallicities. Of the 27 objects, 22 are within 25 pc and 4 appear to be subdwarfs. There are published parallaxes for 18 objects, and all but 4 agree to within 2<i>σ<i/>. The discrepancies are discussed.
