Who’s right? It’s hard to tell based on what Trump has disclosed so far. In his statement on Wednesday, Trump said he had income of $362 million last year. That didn’t included dividends or other capital gains. After taxes, that’s $217 million. If Trump were a stock, for him to be worth $10 billion, he would have a price-to-earnings ratio of 46. Facebook FB 4.83% has a p/e that’s roughly equivalent to that. But the social network’s cash flow is rising by 40% a year. Trump’s, likely, is not.
