Principal Capital Appreciation Fund 

This fund primarily invests in the stock of companies across all market capitalizations, though it demonstrates a notable inclination towards larger capitalization businesses rather than small or medium-sized ones. The portfolio managers look for companies whose shares they believe are undervalued compared to their intrinsic private market worth (the theoretical sale price of the entire business). Additionally, they favor businesses that boast a strong competitive edge or operate in sectors with significant hurdles for new entrants.
