Maybe you can judge a book by its cover. Or better maybe you can judge a company's stock performance by the size of its CEO's house.
That appears to be the conclusion of a study by professors at Arizona State University and New York University. As Bertha Coombs reports, the bigger the house, the more likely the stock under-performed the average..
The study covers most of the CEOs of S&P 500 companies. If the CEO's house was larger than the average -- about 6,000 square feet -- then the company's stock underperfomed by about 3.35%. In the case of mega homes -- 10,000 square feet or more -- those stocks underrperfomred by 6.9%.
Here's how the authors, Crocker H. Liu and David Yermack put it in their study "Where are the Shareholders' Mansions? CEOs' Home Purchases, Stock Sales, and Subsequent Company Performance":
"When a CEO buys real estate, future company performance is inversely related to the CEO's liquidation of company shares and options for financing the transaction. We also find that, regardless of the source of finance, future company performance deteriorates when CEOs acquire extremely large or costly mansions and estates. We therefore interpret large home acquisitions as signals of CEO entrenchment." (Full study)
