Each quarter, the largest US investment managers publish their "13F" on the SEC (Securities and Exchange Commission) website. These quarterly reports list the assets under management of investment managers with control over more than $100 million in assets and who hold so-called "long" US positions. Form 13F covers Registered Investment Advisers (RIAs), banks, insurance companies, hedge funds, trust companies, pension funds and mutual funds. This report is published no later than 45 days after the end of the quarter concerned. The cut-off date was 08/16/2021 for the second quarter (Q2 2021).

The only real new position is Organon & Co, a pharmaceutical company primarily engaged in the development and supply of women's health solutions and biosimilars. However, the size of this position should be put into perspective. It weighs only 0.02% of its portfolio.
