George Soros (Trades, Portfolio) recently submitted the 13F filing for the third quarter of 2025, providing insights into his investment moves during this period. Born in Budapest in 1930, George Soros (Trades, Portfolio) is chair of Soros Fund Management LLC. As one of historys most successful financiers, his views on investing and economic issues are widely followed. Soros established the Quantum Group of Funds hedge fund in 1973; the lead Quantum Fund famously shorted the British Pound in 1992. Soros converted his hedge fund into a family investment office in 2011; Soros Fund Management is advisor to the fund. His basic theory of investing is that financial markets are chaotic. The prices of stocks, bonds and currencies depend on the human beings who buy and sell them, and those traders often act out of highly emotional reactions rather than coolly logical calculations. Opportunities can be found by carefully studying the value and the market prices of assets. He focuses on a theory of “reflexivity,” which is based on the premise that individual investor biases affect market transactions and the economy.
