T. Rowe Price New Horizons Fund 

This fund's primary objective is to achieve substantial capital appreciation over the long term. It predominantly allocates capital to a diverse array of smaller, developing companies, particularly those in their formative stages, well before they gain widespread attention from investors. Furthermore, the fund has the flexibility to acquire stakes in businesses exhibiting potential for accelerated profit expansion, driven by factors such as revitalized leadership, innovative product introductions, or significant shifts in the economic landscape.
