Stocks: Where can I find a list of bankrupt/diluting stocks in the US?
The only recommendation I have is to try the stock screener from Google Finance : https://www.google.com/finance?ei=oJz9VenXD8OxmAHR263YBg#stockscreener
It's difficult to compile free information because the large providers are not yet permitted to provide bulk data downloads by their sources.  As better advertising revenue arrangements that mimic youtube become more prevalent, this will assuredly change, based upon the trend. The data is available at money.msn.com.  Here's an example for ASX:TSE.  You can compare that to shares outstanding here. They've been improving the site incrementally over time and have recently added extensive non-US data.  Non-US listings weren't available until about 5 years ago. I haven't used their screener for some years because I've built my own custom tools, but I will tell you that with a little PHP knowledge, you can build a custom screener with just a few pages of code; besides, it wouldn't surprise me if their screener has increased in power.  It may have the filter you seek already conveniently prepared. Based upon the trend, one day bulk data downloads will be available much like how they are for US equities on finviz.com.  To do your part to hasten that wonderful day, I recommend turning off your adblocker on money.msn and clicking on a worthy advertisement.  With enough revenue, a data provider may finally be seduced into entering into better arrangements.  I'd much rather prefer downloading in bulk unadulterated than maintain a custom screener. money.msn has been my go to site for mult-year financials for more than a decade.  They even provide limited 10-year data which also has been expanded slowly over the years. You could try asking Merrill Lynch, (general inquiries) :- http://www.ml.com/index.asp?id=7695_114042 So far I only found a few graphics :-    http://topics.nytimes.com/top/news/business/companies/merrill_lynch_and_company/ http://www.reuters.com/article/2008/01/17/us-merrilllynch-results-idUSWNAS674520080117 http://www.stocktradingtogo.com/2008/09/15/merrill-lynch-saved-by-bank-of-america-buyout/ There is no way to know anything about who has shorted stuff or how concentrated the positions are in a few investors.  Short positions are not even reported in 13(F) institutional filings. I'll take the bonus points, though, and point you to the US Equity Short Interest data source at quandl. I've seen this tool.  I'm just having a hard time finding where I can just get a list of all the companies.    For example, you can get up to 100 results at a time, if I just search latest filings for 10-K.  This isn't really an efficient way to go about what I want. "Considering the fact that you are so unaware of how to find such data, I find it very very hard to believe that you actually need it. ""All trade and finance data for as much tickers and markets as possible."" Wtf does that even mean. You could be referencing thousands of different types of data for any given ""ticker"" with a statement so vague. What are you looking for?" You can avoid companies that might go bankrupt by not buying the stock of companies with debt. Every quarter, a public company must file financials with the EDGAR system called a 10-Q. This filing includes unaudited financial statements and provides a continuing view of the company's financial position during the year. Any debt the company has acquired will appear on this filing and their annual report. If servicing the debt is costing the company a substantial fraction of their income, then the company is a bankruptcy risk. "There are several such ""lists."" The one that is maintained by the company is called the shareholder registry. That is a list that the company has given to it by the brokerage firms. It is a start, but not a full list, because many individual shareholders hold their stock with say Merrill Lynch, in ""street name"" or anonymously. A more useful list is the one of institutional ownership maintained by the SEC. Basically, ""large"" holders (of more than 5 percent of the stock) have to register their holdings with the SEC. More to the point, large holders of stocks, the Vanguards, Fidelitys, etc. over a certain size, have to file ALL their holdings of stock with the SEC. These are the people you want to contact if you want to start a proxy fight. The most comprehensive list is held by the Depositary Trust Company. People try to get that list only in rare instances." I was going to comment above, but I must have 50 reputation to comment. This is a question that vexes me, and I've given it some thought in the past. Morningstar is a good choice for simple, well-organized financial histories.   It has more info available for free than some may realize.  Enter the ticker symbol, and then click either the Financials or the Key Ratios tab, and you will get 5-10 years of some key financial stats.  (A premium subscription is $185 per year, which is not too outrageous.) The American Association of Individual Investors (AAII) provides some good histories, and a screener, for a $29 annual fee. Zacks allows you to chart a metric like EPS going back a long ways, and so you can then click the chart in order to get the specific number.  That is certainly easier than sorting through financial reports from the SEC.  (A message just popped up to say that I'm not allowed to provide more than 2 links, so my contribution to this topic will end here.  You can do a search to find the Zacks website.  I love StackExchange and usually consult it for coding advice.  It just happens to be an odd coincidence that this is my first answer.  I might even have added that aside in a comment, but again, I can't comment as of yet.) It's problem, however, that the universe of free financial information is a graveyard of good resources that no longer exist.  It seems that eventually everyone who provides this information wants to cash in on it.  littleadv, above, says that someone should be paid to organize all this information. However, think that some basic financial information, organized like normal data (and, hey, this is not rocket science, but Excel 101) should be readily available for free.  Maybe this is a project that needs to happen.  With a mission statement of not selling people out later on. The closest thing out there may be Quandl (can't link; do a search), which provides a lot of charts for free, and provides a beautiful and flexible API.  But its core US fundamental data, provided by Sharadar, costs $150 per quarter.  So, not even a basic EPS chart is available there for free. With all of the power that corporations have over our society, I think they could be tabulating this information for us, rather than providing it to us in a data-dumb format that is the equivalent of printing a SQL database as a PDF!  A company that is worth hundreds of billions on the stock market, and it can't be bothered to provide us with a basic Excel chart that summarizes its own historical earnings?  Or, with all that the government does to try to help us understand all of these investments, they cannot simply tabulate some basic financial information for us? This stuff matters a great deal to our lives, and I think that much of it could and should be available, for free, to all of us, rather than mainly to financial professionals and those creating glossy annual reports. So, I disagree that yet another entity needs to be making money off providing the BASIC transparency about something as simple as historical earnings. Thank you for indulging that tangent.  I know that SE prides itself on focused answers.  A wonderful resource that I greatly appreciate. Patrick Byrne (CEO of Overstock.com) ran a somewhat interesting website awhile back called 'Deep Capture' which focused heavily on naked short selling and bear raids. He was called all sorts of names and many 'serious' journalist types brushed his allegations off.   His basic argument was that a cabal of hedge funds would simultaneously naked short a specific equity and then a coordinated group of journalists and message board jockeys would disparage the company as loudly and publicly as possible, driving the price down. Naked shorting is supposed to be illegal since you can hold the types of positions like in the linked article about Citigroup where the number of shares sold short actually exceeds the number of shares in existence.  The group he named was essentially a who's who of hedge funds and fraudsters and included many names of prominent politically active 'reformed' criminals from the S&amp;L days on Wall St. I can't remember how the cards fell, but the scheme allegedly involved Michael Milliken, Sam Antar (from Crazy Eddie's Fraud), Gary Weiss, Jim Cramer, etc etc.   It was a fascinating story.   Byrne actually followed through with several lawsuits (one of which was settled after a Rocker Partners paid Byrne $5 million dollars to settle).   The 'Deep Capture' site is down, but I [found a decent article](http://www.theregister.co.uk/2008/10/01/wikipedia_and_naked_shorting/print.html) that sums up some of the shenanigans, including a journalist sock-puppeting to edit Wikipedia, repeatedly denying it, being IP-traced to inside the DTCC building (the Wall St. entity responsible for clearing trades, including naked shorts). "Google Finance certainly has data for Tokyo Stock Exchange (called TYO on Google) listings.  You could create a ""portfolio"" consisting of the stocks you care about and then visit it once per day (or write a script to do so)." In order to see whether you can buy or sell some given quantity of a stock at the current bid price, you need a counterparty (a buyer) who is willing to buy the number of stocks you are wishing to offload. To see whether such a counterparty exists, you can look at the stock's order book, or level two feed. The order book shows all the people who have placed buy or sell orders, the price they are willing to pay, and the quantity they demand at that price. Here is the order book from earlier this morning for the British pharmaceutical company, GlaxoSmithKline PLC.  Let's start by looking at the left-hand blue part of the book, beneath the yellow strip. This is called the Buy side. The book is sorted with the highest price at the top, because this is the best price that a seller can presently obtain. If several buyers bid at the same price, then the oldest entry on the book takes precedence. You can see we have five buyers each willing to pay 1543.0 p (that's 1543 British pence, or £15.43) per share. Therefore the current bid price for this instrument is 1543.0. The first buyer wants 175 shares, the next, 300, and so on. The total volume that is demanded at 1543.0p is 2435 shares. This information is summarized on the yellow strip: 5 buyers, total volume of 2435, at 1543.0. These are all buyers who want to buy right now and the exchange will make the trade happen immediately if you put in a sell order for 1543.0 p or less. If you want to sell 2435 shares or fewer, you are good to go. The important thing to note is that once you sell these bidders a total of 2435 shares, then their orders are fulfilled and they will be removed from the order book. At this point, the next bidder is promoted up the book; but his price is 1542.5, 0.5 p lower than before. Absent any further changes to the order book, the bid price will decrease to 1542.5 p. This makes sense because you are selling a lot of shares so you'd expect the market price to be depressed. This information will be disseminated to the level one feed and the level one graph of the stock price will be updated. Thus if you have more than 2435 shares to sell, you cannot expect to execute your order at the bid price in one go. Of course, the more shares you are trying to get rid of, the further down the buy side you will have to go. In reality for a highly liquid stock as this, the order book receives many amendments per second and it is unlikely that your trade would make much difference. On the right hand side of the display you can see the recent trades: these are the times the trades were done (or notified to the exchange), the price of the trade, the volume and the trade type (AT means automatic trade).  GlaxoSmithKline is a highly liquid stock with many willing buyers and sellers. But some stocks are less liquid. In order to enable traders to find a counterparty at short notice, exchanges often require less liquid stocks to have market makers. A market maker places buy and sell orders simultaneously, with a spread between the two prices so that they can profit from each transaction. For instance Diurnal Group PLC has had no trades today and no quotes. It has a more complicated order book, enabling both ordinary buyers and sellers to list if they wish, but market makers are separated out at the top. Here you can see that three market makers are providing liquidity on this stock, Peel Hunt (PEEL), Numis (NUMS) and Winterflood (WINS). They have a very unpalatable spread of over 5% between their bid and offer prices. Further in each case the sum total that they are willing to trade is 3000 shares. If you have more than three thousand Dirunal Group shares to sell, you would have to wait for the market makers to come back with a new quote after you'd sold the first 3000. I think Infochimps has what you are looking for: NYSE and NASDAQ. (yes, this should probably be a comment, not an answer ... but it's a bit long). I don't know what the laws are specifically about this, but my grandfather used to be on the board of a company that he helped to found ... and back in the 1980s, there was a period when the stock price suddenly quadrupled One of the officers in the company, knowing that the stock was over-valued, sold around a third of his shares ... and he got investigated for insider trading.  I don't recall if he was ever charged with anything, but there were some false rumors spreading about the company at the time (one was that they had something that you could sprinkle on meat to reduce the cholesterol).  I don't know where the rumors came from, but I've always assumed it was some sort of pump-and-dump stock manipulation, as this was decades before they were on the S&P 500 small cap. After that, the company had a policy where officers had to announce they were selling stock, and that it wouldn't execute for some time (1? 2 weeks? something like that).  I don't know if that was the SEC's doing, or something that the company came up with on their own. "You can see all the (millions) of trades per day for a US stock only if you purchase that data from the individual exchanges (NYSE, NASDAQ, ARCA, ...), from a commercial market data aggregator (Bloomberg, Axioma, ...), or from the Consolidated Tape Association.  In none of that data will you ever find identifying information for the traders. What you are recalling regarding the names of ""people from the company"" trading company stock is related to SEC regulations stating that people with significant ownership of company stock and/or controlling positions on the company board of directors must publicize (most of) their trades in that stock.  That information can usually be found on the company's investor relations website, or through the SEC website." Technically, of course. Almost any company can go bankrupt. One small note: a company goes bankrupt, not its stock. Its stock may become worthless in bankruptcy, but a stock disappearing or being delisted doesn't necessarily mean the company went bankrupt. Bankruptcy has implications for a company's debt as well, so it applies to more than just its stock. I don't know of any historical instances where this has happened, but presumably, the warning signs of bankruptcy would be evident enough that a few things could happen.  Another company, e.g. another exchange, holding firm, etc. could buy out the exchange that's facing financial difficulty, and the companies traded on it would transfer to the new company that's formed. If another exchange bought out the struggling exchange, the shares of the latter could transfer to the former. This is an attractive option because exchanges possess a great deal of infrastructure already in place. Depending on the country, this could face regulatory scrutiny however. Other firms or governments could bail out the exchange if no one presented a buyout offer. The likelihood of this occurring depends on several factors, e.g. political will, the government(s) in question, etc. For a smaller exchange, the exchange could close all open positions at a set price. This is exactly what happened with the Hong Kong Mercantile Exchange (HKMex) that MSalters mentioned. When the exchange collapsed in May 2013, it closed all open positions for their price on the Thursday before the shutdown date. I don't know if a stock exchange would simply close all open positions at a set price, since equity technically exists in perpetuity regardless of the shutdown of an exchange, while many derivatives have an expiration date. Furthermore, this might not be a feasible option for a large exchange. For example, the Chicago Mercantile Exchange lists thousands of products and manages hundreds of millions of transactions, so closing all open positions could be a significant undertaking.  If none of the above options were available, I presume companies listed on the exchange would actively move to other, more financially stable exchanges. These companies wouldn't simply go bankrupt. Contracts can always be listed on other exchanges as well. Considering the high level of mergers and acquisitions, both unsuccessful and successful,  in the market for exchanges in recent years, I would assume that option 1 would be the most likely (see the NYSE Euronext/Deutsche Börse merger talks and the NYSE Euronext/ICE merger that's currently in progress), but for smaller exchanges, there is the recent historical precedent of the HKMex that speaks to #3. Also, the above answer really only applies to publicly traded stock exchanges, and not all stock exchanges are publicly-held entities. For example, the Shanghai Stock Exchange is a quasi-governmental organization, so I presume option 2 would apply because it already receives government backing. Its bankruptcy would mean something occurred for the government to withdraw its backing or that it became public, and a discussion of those events occurring in the future is pure speculation.
