General Growth Properties lost nearly 50% of its stock value and over $1 billion in market cap today. The reason? The Wall St. Journal confirmed the story that we were following ten days ago: that GGP’s CFO, Bernard Freibaum, was dumping $30 million worth of stock at the 52-week low. Well at least Bernard got to cash out at the old stock price while the rest of the sap shareholders have just had 50% of their money erased. The board should fire this guy.
