How does the purchase of shares on the secondary market benefit the issuing company?
Stock trading (as opposed to IPO) doesn't directly benefit the company. But it affects their ability to raise additional funds; if they're valued higher, they don't need to sell as many shares to raise a given amount of money.  And the stockholders are part owners of the company; their votes in annual corporate meetings and the like can add up to a substantial influence on the company's policies, so the company has an interest in keeping them (reasonably) happy. Dividends (distributing part of the company's profits to the stockholders) are one way of doing so. You're still investing in the company. The fact that you're buying someone else's share just means you're doing so indirectly, and they're dis-investing at the same time. First, the stock does represent a share of ownership and if you have a different interpretation I'd like to see proof of that. Secondly, when the IPO or secondary offering happened that put those shares into the market int he first place, the company did receive proceeds from selling those shares. While others may profit afterward, it is worth noting that more than a few companies will have secondary offerings, convertible debt, incentive stock options and restricted stock that may be used down the road that are all dependent upon the current trading share price in terms of how useful these can be used to fund operations, pay executives and so forth. Third, if someone buys up enough shares of the company then they gain control of the company which while you aren't mentioning this case, it is something to note as some individuals buy stock so that they can take over the company which happens. Usually this has more of an overall plan but the idea here is that getting that 50%+1 control of the company's voting shares are an important piece to things here.
"When there is a trade the shares were both bought and sold. In any trade on the secondary market there has to be both a buyer and a seller for the trade to take place. So in ""lasttradesize"" a buyer has bought the shares from a seller." "With regards to ""the stock market,"" there are actually two markets involved here: PRIMARY MARKET Value is created in the primary market where capital is exchanged for a residual interest in an opportunity.  As a theoretical example, if a person operating solo (or with a small team) were to discover or create a breakthrough product, such as an retro-aging pill, that person likely wouldn't have the financial means to fully capitalize on his new-found idea.  Others with more capital may also soon discover his idea or improve upon it and exploit it before he has a chance to. For a real life example, a person studying at a California university during the 1990s discovered a method to index internet webpages and was approached by some students after a talk on the subject.  He returned to his native southern Europe country seeking funds to develop the web-indexing business and failed to do so.  Two of the students that approached him found capital readily available from investors in their campus sphere; their business is today one of the biggest in the world.  They had exchanged part of their residual interest for capital to develop their business. The primary market of the stock market works mostly same in creating value.  It is also dependent upon the secondary market. SECONDARY MARKET The secondary market indicates the day-to-day value of an enterprise.  That market allows shareholders to manage their risk appetites and the enterprise's operators to execute their shareholders' interest for gains.  In most cases, a secondary market reference will be used for pricing a primary market issuance.  Without that reference, capital would be allocated less efficiently creating additional costs for all involved, issuers and investors. Consider what would happen if you sought to purchase a house and the mortgage lenders had no indication what the property was worth.  This would make capital very expensive or possibly deny you access to credit.  By having an indication, all involved are better off.  That is value creating. There are some large developed economies' equity markets, such as that in Germany, where many large enterprises stay privately held and credit financing, mostly from banks, is used.  The approach has proven successful as well. So why do some nations' financial markets still rely on capricious stock markets when private credit financing may do just fine in many cases?  It's largely a matter of national culture.  Countries such as the Netherlands, the UK and the US have long had active equity markets in continuous use that investors have trusted for centuries. CONCLUSION When leaders of an enterprise wish to grow the business to a large size with investment from the stock market, they aren't limited by the size of their banks' capital.  Those leaders and their prospective investors will rely on the secondary market to determine values.  In addition, if the leaders raise equity instead of debt capital, they are usually accorded more flexibility to take risks since shareholders usually have their own flexibility to transfer those risks to other investors if for any number of reasons they choose to do so. Stock markets create value in many other ways.  The above are the main ways." $38 was the IPO price. This was price per share for those investors who bought directly from the underwriters (Morgan Stanley, etc.)  $42.06 was the first secondary market price, the price at which two private parties first exchanged the shares on an exchange, in this case NASDAQ. In the case you mentioned, where a private company owners will take debt with the purpose of  buying out other owners, is this done through a share repurchases program (I understand private companies issue them, even though it's rare)? Thank you for the insights. "Any shares you buy when a company is listed on one market will remain yours if the company moves to another market. Markets and exchanges like AIM are just venues for dealing in shares - indeed you can deal in those shares anywhere else that will allow you as well as on the AIM. The benefit of being listed in a market is that trade in the shares will be more ""liquid"" - there's more likely to be people who want to buy and sell them at any given time. The bigger concern would be what happens if the company does badly and drops out of the AIM entirely. You'd still be able to sell your shares to any willing buyer, but finding that buyer might get harder." Day traders see a dip, buy stocks, then sell them 4 mins later when the value climbed to a small peak. What value is created? Is the company better off from that trade? The stocks were already outside of company hands, so the trade doesn't affect them at all. You've just received money from others for no contribution to society. A common scenario is a younger business having a great idea but not enough capital funds to actually get the business going. So, investors buy shares which they can sell later on at a higher value. The investor gets value from the shares increasing over time, but the business also gets value of receiving money to build the business. Another benefit of holding shares longer was just pointed out in another question: donating appreciated shares to a nonprofit may avoid the capital gains tax on those shares, which is a bigger savings the more those shares have gone up since purchase. What prevents a company from doing secondary public stock offerings on regular basis? The primary goal of a company doing secondary public offering is to raise more funds, that can be utilized for funding the business. If no funding is needed [i.e. company has sufficient funds, or no expansion plans], this funding creates a drag and existing shareholder including promoters loose value. For example with the current 100 invested, the company is able to generate say 125 [25 as profit]. If additional 100 is taken as secondary public offering, then with 200, the company should mark around 250, else it looses value. So if the company took additional 100 and did not / is not able to deploy in market, on 200 they still make 25 as profit, its bad. There are other reasons, i.e. to fight off hostile acquisition or dilute some of promoters shares etc. Thus the reasons for company to do a secondary PO are few and doing it often reduces the value for primary share holders as well as minority share holders. I once bought both preferred and common shares in a bankrupt company.  It is true that those preferred shares had less potential for appreciation than the common shares.  The reason is because the preferred shares were trading around $50 and had a face value of $1000.  This means that if the bankruptcy proceedings ended up finding enough assets to make the preferred shares whole, then the preferred shareholders would be paid $1000 per share and no more than that.  So if you bought the preferred shares at $50 and received $1000 per share for them, then you made a 1900% gain. But if the bankruptcy proceedings found enough assets to pay not just the preferred shareholders but also the common shareholders, then the common shareholders had the potential for a greater gain than the preferred shareholders.  The common stock was trading around 20 cents at the time, and if enough assets were found to pay $10 per share to the common shareholders, then that would have been a 4900% gain.  The preferred shares were capped by their face value, but the common shares had no limit on how high they could go. from what i understand, which is not much, some companies use some of their own company shares as securitisation for loans. If the share price decreases, the security in the loan decreases, which means the company would need to find new capital. It can create a vicious cycle if the fall in share price is the result of operational concerns. "listed simultaneously in New York, London, and maybe even some Asian markets - is this correct? If the exchanges are not connected, then in primary market the shares are listed. On other exchanges, the ""Depository Receipts"" are listed. i.e. the Company will keep say 100,000 shares with the primary stock exchange / depository. Based on this it would create new instruments ""Depository Receipts"". They can be 1:1 or whatever ratio. hypothetically, if I want to buy all of the company's stock Even if it is on one exchange, buying all stocks would trigger various regulatory aspects of Companies Act, or Stock Exchange rules. This is not simple or easy like clicking some buttons and buying everything. That is, let's say that in New York the company has listed 1000 shares, and in London only 10 shares, each worth 10 USD Market capitalization is sum of all outstanding shares into value." Your impression about banks and bankers is very wrong.  Wall street banks can and often do lose in transactions.  In fact, banks go bankrupt and/or require massive bailouts to survive because they sometimes lose a ton of money.  The business of investment banking often involves bearing risk for customers, which, by definition, means they lose some of the time.  Generally the risks they take on individual transactions are not large enough to bring the whole bank down, but sometimes they are.  Banking is a job like any other, except that it has more risk than most. Anyway, to your point, how do underwriters make money on shares that fall in value before the sale?  On the commission.  The issuing company will normally pay the investment bank a percentage of the funds raised in the offering, regardless of the price.  Of course, it's possible for the bank to still lose money if their contract stipulates a minimum price and they are not able to meet it.  In that case, the bank may lose on that offering, contradicting your preconceived notion. By the way, one other question implicit in your post: Why was the secondary offering considered bad news?  If the CEO and other insiders have private information that indicates that the stock is overvalued, then doing a secondary offering at the inflated price will greatly enrich them.  Because this happens some times, investors are wary about secondary offerings.  This makes companies that would otherwise do a secondary offering shy away from it, even if shares are not overpriced.  Therefore if a company is doing a secondary offering, the market is likely to worry that the stock is overvalued even at a reduced price. After a company goes public, if it wants to raise more money, then it does this by secondary public offering or rights issue. In subscription rights issue gives the right to existing share holders to buy new shares at equal proportion. So if every one buys, they maintain the same percentage of ownership. Generally the pricing is at discount to current market price. Not sure why the price is high, unless the price for this stock fell sharply recently. the implications are that the company's earnings per share may seem greater, (after the company buys them there will be less shares outstanding), giving wall street the impression that there is more growth potential than there really is. its an accounting gimmick that can work for a few quarters while the company evaluates how else to impress wall street On NYSE it isn't the equity which is listed but is an ADR(American Depositary Receipt). Source A negotiable certificate issued by a U.S. bank representing a specified number of shares (or one share) in a foreign stock that is traded on a U.S. exchange. ADRs are denominated in U.S. dollars, with the underlying security held by a U.S. financial institution overseas. ADRs help to reduce administration and duty costs that would otherwise be levied on each transaction. Else people would make a killing on the arbitrage opportunity. Frankly speaking arbitrage opportunities are more or less non existent. They occur for maybe seconds or milliseconds and the HFT firms and banks trade on it to remove the arbitrage.
