$1M with 50% interest

Warren Buffet claims there are ways to grow small sums of money (like $1M 😵) at 50% rate/yr:

• Find securities in your area of competence. Small companies you know a lot about.
• Find "wrinkles in the market", companies with great P/E ratios, that are over-looked by other investors.
• Look at smaller securities, that are ignored by larger hedge funds and with small competition.
