Is there a list of OTC stocks being added to the major exchanges?
"Check your broker's IPO list. Adding a new stock to a stock exchange is called ""Initial Public Offering"" (IPO), and most brokers have a list of upcoming IPO's in which their clients can participate." Reuters has a service you can subscribe to that will give you lots of Financial information that is not readily available in common feeds.  One of the things you can find is the listing/delist dates of stocks.  There are tools to build custom reports.  That would be a report you could write.  You can probably get the data for free through their rss feeds and on their website, but the custom reports is a paid feature. FWIW re-listing(listings that have been delisted but return to a status that they can be listed again) is pretty rare.  And I can not think of too many(any actually) penny stocks that have grown to be listed on a major exchange.
Thanks to the other answers, I now know what to google for. Frankfurt Stock Exchange: http://en.boerse-frankfurt.de/equities/newissues London Stock Exchange: http://www.londonstockexchange.com/statistics/new-issues-further-issues/new-issues-further-issues.htm I don't see it in any of the exchange feeds I've gone through, including the SIPs. Not sure if there's something wrong with Nasdaq Last Sale (I don't have that feed) but it should be putting out the exact same data as ITCH. You haven't looked very far if you didn't find index tracking exchange-traded funds (ETFs) on the Toronto Stock Exchange. There are at least a half dozen major exchange-traded fund families that I'm aware of, including Canadian-listed offerings from some of the larger ETF providers from the U.S. The Toronto Stock Exchange (TSX) maintains a list of ETF providers that have products listed on the TSX. I wouldn't think so.  If you read the list of features listed on the page you referred to, notice: Track Stocks It looks like it is restricted to the major U.S. stock markets.  No mention of India's NSE. The easiest route for you to go down will be to consult wikipedia, which will provide a comprehensive list of all US stock exchanges (there are plenty more than the ones you list!). Then visit the websites for those that are of interest to you, where you will find a list of holiday dates along with the trading schedule for specific products and the settlement dates where relevant. In answer to the other part of your question, yes, a stock can trade on multiple exchanges. Typically (unless you instruct otherwise), your broker will route your order to the exchange where it can be matched at the most favorable price to you at that time. "It's easy to own many of the larger UK stocks. Companies like British Petroleum, Glaxo, and Royal Dutch Shell, list what they call ADRs (American Depositary Receipts) on the U.S. stock exchanges. That is, they will deposit local shares with Bank of NY Mellon, JP Morgan Chase, or Citicorp (the three banks that do this type of business), and the banks will turn around and issue ADRs equivalent to the number of shares on deposit. This is not true with ""small cap"" companies. In those cases, a broker like Schwab may occasionally help you, usually not. But you might have difficulty trading U.S. small cap companies as well." If you have an account with a major bank they may trade an over the counter option with you. Just depends how much work you need to go through and how much you are planning on buying. I don't think that you will be able to find a list of every owner for a given stock. There are probably very few people who would know this. One source would be whoever sends out the shareholder meeting mailers.  I suspect that the company itself would know this, the exchange to a lesser extent, and possibly the brokerage houses to a even lesser extent. Consider these resources: Something to consider is that in the case of the company you chose, on the OTC market, that stock is thinly traded and with such low volume, it can be easy for it to fluctuate greatly to have trades occur.  This is why volume can matter for some people when it comes to buying shares. Some OTC stocks may have really low volume and thus may have bigger swings than other stocks that have higher volume. As Chris pointed out in his comment, smaller stock exchanges may use open outcry. There are several exchanges that use open outcry/floor trading in the US, however, although they aren't necessarily stock exchanges.  Having visited the three Chicago exchanges I mentioned, I can personally vouch for their continued use of a trading floor, although its use is declining in all three. "I think that any ETF is ""open source"" -- the company issues a prospectus and publishes the basket of stocks that make up the index. The stuff that is proprietary are trading strategies and securities or deriviatives that aren't traded on the open market. Swaps, venture funds, hedge funds and other, more ""exotic"" derivatives are the things that are closed. What do you mean by ""open source"" in this context?" "Edgar Online has this information for companies under SEC regulations and they are reported in ""Form 4"" so that should help guide your search" "To other users save yourselves time, do not test any of the alternatives mentioned in this post. I have, to no avail. At the moment (nov/2013) Saxobank unfortunately seems to be the only broker who offers OTC (over-the counter) FX options trading to Retail Investors. In other words, it is the only alternative for those who are interested in trading non-exchange options (ie, only alternative to those interested in trading FX options with any date or strike, rather than only one date per month and strikes every 50 pips only). I say ""unfortunately"" because competition is good, Saxo options spreads are a rip off, and their platform extremely clunky. But it is what it is." "If by ""most public companies"" you mean ALL public companies. Heck, even some non-public companies have to file 10-Ks.  OP, I'd avoid any exchange-based list (a public company may be de-listed, for example) and go right to the source: Edgar." OTC markets group definitely has a lot of foreign and startup issuer is the tech field. Also you have to define technology. Do you want computer technology, engineering, hardware manufacturing, software companies, biotech, or something else? Technology can mean many things and what you specifically want may end up shaping your portfolio. Also technology is a volatile sector I'd diversify with something more stable like utilities or basic materials if I were you.
