Copying billionaires' trades is a tactic that's been used by retail investors for decades to build their portfolios. By tracking the buys and sells on quarterly 13-F filings from hedge fund managers and other deep-pocketed investors, investors can attempt to replicate the strategies used by the market veterans who have built their fortunes by picking critical winners across various market cycles.
Although this strategy may appear to be foolproof, timing is everything in the markets, and it's important to remember that these quarterly filings aren't real-time updates on what our favorite billionaire investors are doing with their stacks of capital. Plus, billionaires can also go wrong with their bets - whether it was Warren Buffett's heavy investment in Dexter Shoe in the nineties, or Carl Icahn's initial reluctance towards Apple (AAPL), even the most successful and celebrated investors have their personal portfolio horror stories.
