Each quarter, hedge funds must disclose their holdings of publicly traded companies.

WalletHub, a personal finance site, analyzes the filings of top 400 hedge funds each quarter to see what stocks they were buying up and which they were selling.

Their monitoring includes famous investors and funds like Warren Buffett's Berkshire Hathaway; Ray Dalio's Bridgewater Associates, the world's largest hedge fund; David Tepper's Appaloosa Management; and Daniel Loeb's Third Point Capital.

"It makes sense that people pay attention to what hedge fund managers are buying, selling and holding," the firm said. "We want to replicate their success. Hedge funds' quarterly public disclosures, mandated by the Securities and Exchange Commission, give us a window into their recent activity."
