Contrarian Positioning
Thiel famously advises investors to "find secrets" - ideas that are undervalued or misunderstood by the market. His investments often go against conventional wisdom, focusing on areas where he believes the consensus view is wrong.
Long-Term Horizon
Unlike many investors who seek quick returns, Thiel takes a long-term view, often holding investments for a decade or more. This patience has allowed him to capture extraordinary returns from companies like Facebook and Palantir.
Monopoly Theory
Thiel advocates for creating "monopolies" through technological innovation. He believes that truly valuable businesses create new markets rather than competing in existing ones, a philosophy outlined in his book "Zero to One."
"Competition is for losers. If you want to create and capture lasting value, look to build a monopoly." - Peter Thiel, Zero to One
