A new study sheds light on which companies hedge fund investors have been putting their faith in—as well as their $3 trillion in assets. WalletHub analyzed the second-quarter filings of over 400 of the largest hedge funds to identify their biggest holdings, new positions, recent exits and other relevant data. "It makes sense that people pay attention to what hedge fund managers are buying, selling and holding, especially during these times of economic uncertainty," WalletHub said in the report. "Hedge funds’ quarterly public disclosures, mandated by the Securities and Exchange Commission, give us a window into their recent activity."
