Query: How come we can find stocks with a Price-to-Book ratio less than 1?

Relevant passages:
 <=SEP=> "The VDE fund is an energy fund so this is a function of recent price changes in oil (and gas, coal, &c).   For example. Lets say last year when oil was $100 per barrel a bunch of companies saw a good return and put $ 100 million into a bunch of leases, boreholes, pumps, &c to return $10 million per year, and the market says yeah, they're all together worth 100M. Now oil is less, maybe $40 per the link.  These exploration companies don't have a lot of labor or variable costs; they are operationally profitable, may have ""use it or lose it"" leases or minimum pumping requirements for contract or engineering reasons.  Lets say the cash flow is 7M so the market values them at 70M.  They still have about 100M book value so here we are at .7 and I believe the scenario in the question.  Nobody would invest in new capacity at this oil price.  The well equipment could be repurposed but not the borehole or lease, so the best use is to continue pumping and value it on cash flow.  If an individual well runs negative long enough and goes bust, either a different pumper will pay the minimum price that gives profitable cash flow, or that borehole that cost millions to dig is shut off and rendered valueless.  The CNBC article says some explorers are playing games with debt to maintain yield, so there is that too. In the ETF, your bet is that the market is wrong and oil will go up, increasing future cash flows (or you like the current yield, taking on the risk that some of these oil explorers could go bust)."

 <=SEP=> A lower Price/Book Value means company is undervalued. It could also mean something horribly wrong. While it may look like a good deal, remember;

 <=SEP=> Note that the formula for Price to Book ratio is:  Stock Price / {[Total Assets - (Intangible Assets + Liabilities)] / Stock Outstanding}  http://www.investopedia.com/terms/p/price-to-bookratio.asp  http://www.investopedia.com/articles/fundamental/03/112603.asp  There's a number of factors that could lead to a lower than 1. The primary reason, imho, could be the company is in a state of retiring stock with debt. The company is selling penny stocks (only to get people more interested in it's later development) which are inherently undervalued. There may be other reasons, but definitely check out both articles.

 <=SEP=> Book value = sell all assets and liquidate company . Then it's the value of company on book. Price = the value at which it's share gets bought or sold between investors.  If price to book value is less than one, it shows that an 100$ book value company is being traded at 99$ or below. At cheaper than actually theoretical price. Now say a company has a production plant . Situated at the most costliest real estate . Yet the company's valuation is based upon what it produces, how much orders it has etc while real estate value upon which plant is built stays in book while real investors don't take that into account (to an extend). A construction company might own a huge real estate inventory. However it might not be having enough cash flow to sustain monthly expense. In this scenario , for survival,i the company might have to sell its real estate at discount. And market investors are fox who  could smell trouble and bring price way below the book value  Hope it helps
