Donald Trump would have been twice as rich if he switched from real estate to stocks.
An interesting article ( http://www.moneytalksnews.com/why-youre-probably-better-investing-than-donald-trump/
) shows that Trump would have had $10 billion more if he had switched to a simple S&P 500 fund about 30 years ago.
For his value today, Trump estimates it at $10 billion, while Forbes has him at $4.1 billion. They give him the benefit of the doubt and used $10 billion.
For the value in 1982, Forbes had him at over $200 million but said that Trump claimed $500 million. Again, they used Trump's claim.
So, starting with $500 million in 1982, if he had put it in an S&P 500 fund, he would have made (from 1982 to 12/14) an annualized 11.86%, and his $500 million would have become $20 billion.
This shows that simple investments like stocks, which are available to anyone, are powerful.
It also shows that he isn't that great of a business man.
