Stock Certificate In two names
The DOW is just an index, which is simply a group of stocks meeting the criteria for inclusion. In the case of the DOW, it's the 30 US stocks with the largest market capitalization, but other indices include many lesser stocks (such as the S&P500 or the Russell 2000). The fact that Holobeam is no longer a constituent of the DOW30 probably shouldn't be taken in and of itself as a signal to sell the stock. As far as I can tell, HOOB stock is still trading on the Nasdaq exchange. However, it is extremely ill-liquid, which means that there are very few people willing to buy or sell it. Whether or not this would work to your advantage is almost entirely down to luck - it depends whether there is a keen buyer out there at the time you try to sell. I'd call it pretty worrisome.  HOOB is trading over the counter, in fact, on the pink sheets, so it has been delisted from the major exchanges.  It appears that it lacks recent financial disclosures.  You'll have to investigate to see if you think it's worth keeping, but trading is thin. "The common way to frame the ""should I sell"" question is ask yourself ""would you buy it today at the current price"".  If you wouldn't,  sell it. Is sounds like this may be a paper certificate.  You will have to research how to present the certificate to a broker to trade it, or if the company has a direct shareholder program.  I have periodically been offered to sell ""odd lots"" to shareholder programs which, if one exists, may be less hassle than other options.  As a part of this, your mother's estate administrator should decide if the estate is selling it's interest, or giving it's interest to heirs before the sale."
Yes, depending on what you're trying to achieve. If its just a symbolic gift - you can use a service like this. There are several companies providing this service, look them up, but the prices are fairly the same. You'll end up getting a real stock certificate, but it will cost a lot of overhead (around $40 to get the certificate, and then another $40 to deposit it into a brokerage account if you want to sell it on a stock exchange). So although the certificate is real and the person whose name on it is a full-blown shareholder, it doesn't actually have much value (unless you buy a Google or Apple stock, where the price is much much higher than the fees). Take into account that it takes around 2 months for the certificate to be issued and mailed to you, so time accordingly. Otherwise, you can open a custodial brokerage account, and use it to buy stocks for the minor. Both ways are secure and legal, each for its own purpose and with its own fees. Possibles: stock offering, secondary placement, increase authorized number of shares, shelf registration. I found the following on a stock to mutual conversion for insurance firms for Ohio. Pulling from that link,  Any domestic stock life insurance corporation, incorporated under a general law, may become a mutual life insurance corporation, and to that end may carry out a plan for the acquisition of shares of its capital stock, provided such plan: (A) Has been adopted by a vote of a majority of the directors of such corporation; (B) Has been approved by a vote of stockholders representing a majority of the capital stock then outstanding at a meeting of stockholders called for the purpose; (C) Has been approved by a majority of the policyholders voting at a meeting of policyholders called for the purpose, each of whom is insured in a sum of at least one thousand dollars and whose insurance shall then be in force and shall have been in force for at least one year prior to such meeting.  and Any stockholder who has assented to the plan or who has been concluded by the vote of the assenting stockholders, and any stockholder who has objected and made demand in writing for the fair cash value of his shares subsequent to which an agreement has been reached fixing such fair cash value, but who fails to surrender his certificates for cancellation upon payment of the amount to which he is entitled, may be ordered to do so by a decree of the court of common pleas for the county in which the principal office of such corporation is located after notice and hearing in an action instituted by the corporation for that purpose, and such decree may provide that, upon the failure of the stockholder to surrender such certificates for cancellation, the decree shall stand in lieu of such surrender and cancellation.  Since they successfully became a mutual insurance company, I would guess that those stocks were acquired back by the company, and are leftover from the conversion. They would not represent an ownership in the company, but might have value to a collector. Initially, Each company has 10k shares. Company B has $500k money and possibly other assets. Every company has stated purpose. It can't randomly buy shares in some other firm.   Company A issued 5k new shares, which gives it $500k money. Listed companies can't make private placements without regulatory approvals. They have to put this in open market via Public issue or rights issue. Company B does the same thing, issuing 5k shares for $500k money. Company A bought those 5k shares using the $500k it just got There is no logical reason for shareholder of Company B to raise 5K from Company A for the said consideration. This would have to increase. On NASDAQ the ^ is used to denote other securities and / to denote warrents for the underlying company. Yahoo maybe using some other designators for same. Generally, when I run across this kind of situation, I look for the Investor Relations section of the corporate website for a 'Stock Information' (or similar) tab or link.   This usually contains information explaining the different shares classes, how they relate (if at all), voting and/or dividend rights, and taxation differences for the different classes. However, I have trouble finding such a page on a central BYD corporate investor relations page.   I did find this page detailing the HK1211 shares: http://www.byd.com/investor/base_information.html.  I don't know what or why, but something tells me this is an older page. Searching on, I also found this page which looks newer and clarifies that the difference you are seeing is between 'A' and 'H' shares. http://www.byd.cn/BYDEnglish/basic/article.jsp?articleId=1524676.  (I'm guessing but I'd think somewhere in the announcements on this byd.cn site, you may find more details of any structural differences between share classes -- I just didn't want to page through them all.) There isn't a single universal way to reference a stock, there are 4 major identifiers with many different flavours of exchange ticker (see xkcd:Standards) I believe CUSIPs and ISINs represent a specific security rather than a specific listed instrument. This means you can have two listed instruments with one ISIN but different SEDOLs because they are listed in different places. The difference is subtle but causes problems with settlement Specifically on your question (sorry I got sidetracked) take a look at  CQS Symbol convention to see what everything means "Yes you can. One additional ""advantage"" of getting the physical certificate is you can use it to transfer your account from one brokerage to another.  You get the certificates in the mail and then just send them to the new broker. Why anyone would want to go through this extra work (and usually added expense) rather than a direct transfer is beyond me but it is one additional ""advantage"" of physical certificates." Yes that is the case for the public company approach, but I was referring to the transaction approach:   Firm A and Firm B both have $100 in EBITDA. Firm A has $50 in cash, Firm B has $100 in cash.  Firm A sells for $500, Firm B sells for $600.  If we didn't subtract cash before calculating the multiple: Firm A: 5x Firm B: 6x  If we DO subtract cash before calculating the multiple: Firm A: 4.5x Firm B: 5x  So yea, subtracting cash does skew the multiple. Yes, this can and does certainly happen. When two companies each own stock in each other, it's called a cross holding. I learned about cross holdings in reference to Japanese companies (see Wikipedia - Keiretsu) but the phenomenon is certainly not exclusive to that jurisdiction.  Here are a few additional references: It seems like you want to compare the company's values not necessarily the stock price.  Why not get the total outstanding shares and the stock price, generate the market cap.  Then you could compare changes to market cap rather than just share price. "If I buy the one from NSY, is it the ""real"" Sinopec? No - you are buying an American Depository Receipt. Essentially some American bank or other entity holds a bunch of Sinopec stock and issues certificates to the American exchange that American investors can trade.  This insulates the American investors from the cost of international transactions.   The price of these ADRs should mimic the price of the underlying stock (including changes the currency exchange rate) otherwise an arbitrage opportunity would exist.  Other than that, the main difference between holding the ADR and the actual stock is that ADRs do not have voting rights. So if that is not important to you then for all intents and purposes trading the ADR would be the same as trading the underlying stock." authorized 100,000,000 shares They cannot issue shares more than that so 102M isn't possible. Common stock - $.01 par value, authorized 100,000,000 shares, issued 51,970,721 and 51,575,743 shares     If you look at the right 2 columns it become clear what it means. You missed the $ symbol and on the top (In thousands, except share amounts) ouststanding share 51,970,721 -> 520 On Sept 30, 2014 outstanding shares * 0.01 and rounded off to arrive at 520. ouststanding share 51,575,743 -> 516 On June 30, 2014 outstanding shares * 0.01 and rounded off to arrive at 516. There is a company that will sell you single paper shares of stock for many companies and handle framing. But you pay a large premium over the stock price. Disney stopped doing paper share certificates a while ago, but you should be able to buy some of the old ones on eBay if you want. I find the reg, at last. https://www.sec.gov/cgi-bin/browse-edgar?company=Cornerstone+Strategic+Value+Fund&owner=exclude&action=getcompany Yes, its a common stock.
