SME investments carry high risks such as companies disappearing or becoming worthless. When investing in SMEs, careful due diligence is important. Most SMEs may not survive beyond 10 years as their current value is close to zero. Predicting the future is difficult, but possible outcomes can be estimated based on understanding how industries and the universe works. Success requires both talent and luck. Regression to the mean is a powerful force, so exceptional performance should not be assumed to last forever.
