Fjarde AP-fonden (AP4) is a Swedish state-owned pension fund established in 1974. It manages part of Sweden's public pension capital, investing in listed shares, fixed income, and real assets to maximize long-term returns at low risk[1][3]. AP4's target audience includes the broader Swedish public pension system. Its unique selling proposition is its commitment to responsible and sustainable investments, working closely with the Council on Ethics to exclude companies involved in unethical activities[1][4]. AP4's services focus on asset management and ethical investment strategies.
