After strong performance throughout the year, Bill Ackman's activist hedge fund Pershing Square Holdings ended 2019 with a net performance of 58.1%, the company said in its December portfolio update.

Some of the outperformance - the S&P 500 returned 29% in the same time frame - was credited to none other than the Oracle of Omaha, Warren Buffett. In 2019, Ackman bet big on Berkshire Hathaway, run by Buffett; in August, Berkshire Hathaway shares accounted for roughly 11% of the fund's net asset value, Ackman told investors.

But Ackman had other bets in 2019 that also fueled the outsized returns for the fund.

Those other bets included fast-food companies Starbucks and Chipotle, home-improvement retailer Lowe's, and hospitality company Hilton Worldwide Holdings. In December, the fund announced it had purchased a stake in life-sciences equipment maker Agilent Technologies.

Here are the top eight publicly disclosed positions in Ackman's hedge fund, as of September 30, according to SEC filings. The holdings are ranked from lowest to highest value.
