The Stock Advisors has an article on Loews the holding company (L) as opposed to Lowe's the hardware store (LOW). The author of the article estimates that shares of the company are trading at a 40% discount, based on the value of its holdings:
"We don’t see any rational reason for Loews to be so undervalued. So let’s buy some great assets, top management, a proven track record, and a pile of cash, all at a 40% discount to its value: buy Loews Corp."
The company reports earnings on Monday, so Mr. Market may discount the stock even further, depending what comes out in the earnings report.
