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.
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 TD will only sell the stock for you if there's a buyer. There was a buyer, for at least one transaction of at least one stock at 96.66. But who said there were more? Obviously, the stocks later fell, i.e.: there were not that many buyers as there were sellers. What I'm saying is that once the stock passed/reached the limit, the order becomes an active order. But it doesn't become the only active order. It is added to the list, and to the bottom of that list. Obviously, in this case, there were not enough buyers to go through the whole list and get to your order, and since it was a limit order - it would only execute with the limit price you put. Once the price went down you got out of luck.  That said, there could of course be a possibility of a system failure. But given the story of the market behavior - it just looks like you miscalculated and lost on a bet. It may have some value!  Investopedia has a well-written quick article on how stock holders may still get some portion of the liquidated assets.  While there is generally little left for common shareholders if the price of those shares is tiny and some money does come back to shareholders there can still be significant profit to be made. As to why the trading volume is so high... there are many firms and hedge funds that specialize in calculating the value of and buying distressed debt and stock.  They often compete with each other to by the stock/debt that common shareholders are trying to get rid of.  In this particular case, there is a lot of popular interest, intellectual property at stake and pending lawsuits that probably boosts volume. The company may have put a trading halt due to many reasons, most of the time it is because the company is about to release some news to the market. To stop speculation driving the price up or down, it puts a halt on trading until it can get all the information together and release it to the market. This could be news about an earnings update, a purchase of other businesses, a merger with another business, or a takeover bid, just to name a few. First, I want to point out that your question contains an assumption. Does anyone make significant money trading low volume stocks?  I'm not sure this is the case - I've never heard of a hedge fund trading in the pink sheets, for example. Second, if your assumption is valid, here are a few ideas how it might work: Accumulate slowly, exit slowly.  This won't work for short-term swings, but if you feel like a low-volume stock will be a longer-term winner, you can accumulate a sizable portion in small enough chunks not to swing the price (and then slowly unwind your position when the price has increased sufficiently). Create additional buyers/sellers.  Your frustration may be one of the reasons low-volume stock is so full of scammers pumping and dumping (read any investing message board to see examples of this).  If you can scare holders of the stock into selling, you can buy significant portions without driving the stock price up.  Similarly, if you can convince people to buy the stock, you can unload without destroying the price.  This is (of course) morally and legally dubious, so I would not recommend this practice. people implicity agree to sell stocks when a company does bad But, remember, when you sell the stock of a company that, in your estimation, 'did bad', someone else had to buy; otherwise, there is no sale. The someone else who bought your shares evidently disagrees with your assessment. Did you sell because the company didn't earn a profit at all? Did it not earn a profit because it's in a dead-end business that is slowly but inevitably declining to zero? Something like Sears Holdings? Or did it not make a profit because it is in an emerging market that will possibly someday become hugely profitable? Something like Tesla, Inc.? Did you sell because the company made a profit, but it was lower than expected? Did they make a lower-than-expected profit because of lower sales? Why were the sales lower? Is the industry declining? Was the snow too heavy to send the construction crews out? Did the company make a big investment to build a new plant that will, in a few years, yield even higher sales and profits? What are the profits year-over-year? Increasing? Declining? Usually, investors are willing to pay a premium, that is more than expected, for a stock in a company with robust growth.  As you can see, the mere fact that a company reported a profit is only one of many factors that determine the price of the shares in the market. In the stock market many participants enter orders that are not necessarily set at the current market price of the stock (i.e. they are not market orders, they are limit orders). They can be lower than the market price (if they want to buy) or they can be higher than the market price (if they want to sell). The set of orders at each point of time for a security is called the order book. The lowest selling price of the order book is the offer or ask, the higher buying price is the bid. The more liquid is a security, the more orders will be in the order book, and the narrower will be the bid-ask spread. The depth of the order book is the number of units that the order book can absorb in any direction (buy or sell). As an example: imagine I want to buy 100 units at the lowest offer, but the size of the lowest offer is only 50 units, and there is not any further order, that means the stock has little depth. It's the buying and selling of the stock that causes the fluctuation in prices, not the news. People buy and sell all the time, and not just for newsworthy reasons.  They may have to send a child to college, or fix a roof, etc.  Or they may be technical traders looking for signals.  All kinds of reasons.

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." Because swing trading isn't the only reason to buy a stock, and it's not the only way to make money on a stock.  I do not have the expertise to make advice one way or the other, but I personally I feel swing trading is one of the worse ways to invest in the stock market. To answer your specific questions: In the previous post, I outlined a naive trade intended to make $1,000 off a $10k buy, but it was shown this would likely fail, even if the stock price would have increased by 10% had I not placed the trade. Another way to state this is that my trade would disrupt the stock price, and not in my favor at all. So, that means I'd have to settle for a smaller trade. If I bought $100 worth of the stock, that size of a buy wouldn't be too disruptive. I might succeed and get $10 out of the trade (10% of $100). But my trade fee was $8 or so... To summarize, you are completely correct that even hoping for gains of 10% on a consistent basis (in other words, after every single trade!) is totally unrealistic.  You already seem to understand that swing trading on low-volume stocks is pointless.  But your last question was... So how do people make any significant money trading low volume stocks--if they even do? I assume money is made, since the stocks are bought and sold. I have some guesses, but I'd like to hear from the experts. ... and in a comment: Then if no one does make significant money trading these stocks...what are they doing there on the market?  The answer is that the buying and selling is mostly likely not by swing traders.  It's by investors that believe in the company.  The company is on the market because the company believes public trading to be an advantageous position for them to receive capital investments, and there are people out there who think that transaction makes sense.  In other words, real investing. Depending on the structure of you're portfolio, it could be that your portfolio is delta neutral to take advantage of diminishing time value on options, short straddles/strangles would be an example. Here are some significant factors affect the company stock price performance: Usually, profitability is known to the public through the financial statements; it won't be 100% accurate and people would also trade the stock with the price not matching to the true value of the firm. Still there are dozens of other various reasons exist. People are just not behaving as rational as what the textbook describes when they are trading and investing. If you do this, you own a stock worth $1, with a basis of $2. The loss doesn't get realized until the shares are sold. Of course, we hope you see the stock increase above that price, else, why do this? "There are many reasons. Here are just some possibilities: The stock has a lot of negative sentiment and puts are being ""bid up"". The stock fell at the close and the options reflect that. The puts closed on the offer and the calls closed on the bid. The traders with big positions marked the puts up and the calls down because they are long puts and short calls. There isn't enough volume in the puts or calls to make any determination - what you are seeing is part of the randomness of a moment in time." "You probably bought the stock near the peak because ""it's been up a lot lately."" That's the easiest way to lose money. You need to go back and do some basic research. The stock appears to have been expensive around 75. Why is that? The stock seems to be in a ""comfortable"" level around 45. Why is THAT? Maybe it's too expensive around 45 (based on the P/E ratio, or other measures); maybe you should buy more at 45, where it is cheap, even though 75 is too expensive. The key is to study the stock where it is today (45-47). Ask yourself what you would do at TODAY's price, and today's ""fundamentals."" That will also save you from paying 75 for a stock worth 45, and should save you from paying 45 for a stock if it is only worth 35."
