What could cause a stock to trade below book value?
A company's stock value is indicative of the market's collective belief of the future of the company. The relationship of between price and book value will vary according to the quality of the company, the category of stock, etc. In extreme cases, say Bank of America, the stock trades at a fraction of book, because BOA's books are a fantasy by most people's reckoning. Discrepancies between what the book value is reported as and what they'd fetch if sold on the open market. Legal disputes in court. "The key to evaluating book value is return on equity (ROE). That's net profit divided by book value.  The ""value"" of book value is measured by the company's ROE (the higher the better). If the stock is selling below book value, the company's assets aren't earning enough to satisfy most investors. Would you buy a CD that was paying, say two percentage points below the going rate for 100 cents on the dollar? Probably not. You might be willing to buy it only by paying 2% less per year, say 98 cents on the dollar for a one year CD. The two cent discount from ""book value"" is your compensation for a low ""interest"" rate." all of these examples are great if you actually believe in fundamentals, but who believes in fundamentals alone any more? Stock prices are driven by earnings, news, and public perception. For instance, a pharma company named Eyetech has their new macular degeneration drug approved by the FDA, and yet their stock price plummeted. Typically when a small pharma company gets a drug approved, it's off to the races. But, Genetech came out said their macular degeneration drug was going to be far more effective, and that they were well on track for approval.
Reading financial statements is important, in the sense that it gives you a picture of whether revenues and profits are growing or shrinking, and what management thinks the future will look like. The challenge is, there are firms that make computers read filings for them and inform their trading strategy. If the computer thinks the stock price is below the growth model, it's likely to bid the stock up. And since it's automated it's moving it faster than you can open your web browser. Does this mean you shouldn't read them? In a sense, no. The only sensible trading strategy is to assume you hold things for as long as their fundamentals exceed market value. Financial statements are where you find those fundamentals. So you should read them. But your question is, is it worth it for investors? My answer is no; the market generally factors information in quickly and efficiently. You're better off sticking to passive mutual funds than trying to trade. The better reason to learn to read these filings is to get a better sense of your employer, potential employers, competitors and even suppliers. Knowing what your margins are, what your suppliers margins and acquisitions are, and what they're planning can inform your own decision making. Look at Price/book value and there are more than a few stocks that may have a P/B under 1 so this does happen. There are at least a couple of other factors you aren't considering here: Current liabilities - How much money is the company losing each quarter that may cause it to sell repeatedly. If the company is burning through $100 million/quarter that asset is only going to keep the lights on for another 2.5 years so consider what assumptions you make about the company's cash flow here. The asset itself - Is the price really fixed or could it be flexible? Could the asset seen as being worth $1 billion today be worth much less in another year or two? As an example, suppose the asset was a building and then real estate values drop by 40% in that area. Now, what was worth $1 billion may now be worth only $600 million. As something of a final note, you don't state where the $100 million went that the company received as if that was burned for operations, now the company's position on the asset is $900 million as it only holds a 90% stake though I'd argue my 2 previous points are really worth noting. The Following 6 Stocks Are Trading At or Below 0.5 x Book Value–Sep 2013 has a half dozen examples of how this is possible. If the $100 million was used to pay off debt, then the company doesn't have that cash and thus its assets are reduced by the cash that is gone. Depending on what the plant is producing the value may or may not stay where it is. If you want an example to consider, how would you price automobile plants these days? If the company experiences a reduction in demand, the plant may have to be sold off at a reduced price for a cynic's view here. It looks more like someone is trying to pocket the spread.  The trades are going off at the bid then the ask (from what I can tell without any L1 and L2 data, but the spread could be bigger than what the prices show, since the stock looks pretty volatile given the difference between current price and VWAP...).  Looking through the JSE rule books I didn't find any special provisions on how they handle odd lots in their Central Order Book, but the usual practice in other markets is to display only round lot orders. So these 4 share orders would remain hidden from book participants and could be set there to trigger executions from those who are probing for limit orders. Or to make a market with very limited risk. "An answer can be found in my book, ""A Modern Approach to Graham and Dodd Investing,"" p. 89 http://www.amazon.com/Modern-Approach-Graham-Investing-Finance/dp/0471584150/ref=sr_1_1?s=books&ie=UTF8&qid=1321628992&sr=1-1 ""If a company has no sustained cash flow over time, it has no value...If a company has positive cash flow but economic earnings are zero or less, it has a value less than book value and is a wasting asset. There is enough cash to pay interim dividends, bu the net present value of the dividend stream is less than book value."" A company with a stock trading below book value is believed to be ""impaired,"" perhaps because assets are overstated. Depending on the situation, it may or may not be a bankruptcy candidate." This can arise with very thinly traded stocks for large blocks of shares. If the market only has a few thousand dollars available at between 8.37 and 12.5 the price is largely meaningless for people who want to invest in hundreds of thousands/millions of dollars worth, as the quoted price can't get them anywhere near the number of shares they want. How liquid is the stock in question? The prices dropped because the scandal could mean: This some people estimated that the company could lose money, or have smaller profit. Thus each share was worth less money going forward. The mechanism is that in order to sell their shares the current share owners had to settle for lower prices. "There's an expression, ""stock prices have no memory."" Apple trades at about $115. Why would I carry my shares at anything but $115 even though I paid say $75 a share, while you just bought it at $115?  The only difference, perhaps, is that if I hold them in a non retirement account, I might track the net I'd have, post tax." "Yes, there are situations where a stock is a bad buy in spite of a low PE. PE ratio tells you the current share price divided by the prior 4 quarters earnings per share. It does not consider: Imagine someone walked up to you and said, ""Do you want to buy a piece of my business? I'll sell you 1% of it for $1000. Last year the business earned $25000."" A quick calculation shows a PE of 4 [$1000/($25000 *.01)]. Even though this PE is comparatively low, you wouldn't buy in without a lot more info. What kinds of things might you ask? PE is one tiny component of an informed investment decision."
