Money managers who oversee more than $100 million in equities must file a Form 13F with the Securities and Exchange Commission within 45 days of each quarter’s end to list their U.S.-traded stocks, options and convertible bonds. The filings don’t show non-U.S. securities or how much cash the firms hold.
