The renaming of the fund follows a recent review of the fund holdings and a reshuffle of several of its underlying investments, although investment objective will remain the same.
The fund will typically hold 50-70 stocks. The manager will focus on mid-sized firms and smaller companies within the FTSE 100 index, UBS said.
Since November 2010, Edward Peter-Hoblyn has been managing the fund.
Peter-Hoblyn took over the fund from Brian Gallagher and Frank Manduca. They ran the fund for seven months on an interim basis after Matthew Cox, its previous manager, left the group. Cox had run the fund from March 2006 to February 2010.
