Raymond Dalio is an American businessman who founded Bridgewater Associates, the world's largest hedge fund firm, which manages $155 billion. Dalio was on Time magazine's list of the world's 100 most influential people in 2012. In 2014, Dalio made an estimated $1.2 billion, which put him in second place on Forbes' highest-earning hedge fund managers and traders list.

According to Forbes, as of Feb. 9, 2016, Dalio has a net worth of $15.6 billion. Since Dalio has over $100 million in qualifying assets, he is required to file the SEC Form 13F, which much be filed within 45 days after the end of each quarter. Dalio filed the SEC Form 13F-HR on Nov. 12, 2015 for the quarter ending Sept. 30, 2015. The top five positions in Dalio's portfolio for the third quarter consist of exchange-traded funds (ETFs), which make up nearly 75% of his portfolio.

Vanguard FTSE Emerging Markets ETF

The Vanguard FTSE Emerging Markets ETF (NYSEARCA: VWO) primarily invests in common stocks of companies within emerging-market countries such as China, Taiwan, India and South Africa. The fund carries a high degree of risk, but it has the potential for high growth rates. Therefore, it is best-suited for investors with long-term investment horizons.

Dalio's portfolio owns 67.36 million shares of this ETF, which had a market value of $2.23 billion on Sept. 30, 2015.

SPDR S&P 500 ETF

Dalio's second-largest holding is in the SPDR S&P 500 ETF (NYSEARCA: SPY), which is the most actively traded ETF tracking the S&P 500 Index. This ETF charges an exceptionally low annual net expense ratio of 0.09%, which helps to reduce Dalio's costs.
