Can I buy stock of a company that just IPO
"Yes, you could buy a stock on the day of its IPO. I'm a college student, and I wonder if I can buy stock from a company   right after it finishes its IPO? Yes, you can. However, unless you are friends or family of an employee, chances are you'll be paying a higher price than you think as there is generally a fair bit of hype on most  IPOs that allows some people to ""flip them"" which means someone is buying at a higher price. If I am not allowed to buy its stocks immediately after they go on   sell, how long do I have to wait? Generally I'd wait until the hype dies down as if you look at most historical IPOs the stock could be bought cheaper later but that's just my perspective. And also who are allowed to buy the stocks at the first minute they   are on sell? Anyone but keep in mind that while an IPO may be priced at $x, the initial trades may be a few times that value and the stock may come down over time. Facebook could be an example to consider of a company that had an IPO at one price and then came down for a little while on its chart over the past couple of years."
Two methods:  1: Become really close friend with Marky. Probably have to take a bullet for him or something.   2: Become a major client of the investment bank that will launch the IPO (most likely Goldman), and the bank will offer you some shares before the IPO. In order to become a major client you probably have to spend several millions per year in transaction fee. "Yes, this is possible with some companies. When you buy shares of stock through a stock broker, the shares are kept in ""street name.""  That means that the shares are registered to the broker, not to you.  That makes it easy to sell the stock later.  The stock broker keeps track of who actually owns which shares.  The system works well, and there are legal protections in place to protect the investors' assets. You can request that your broker change the stock to your name and request a certificate from the company.  However, companies are no longer required to do this, and some won't.  Your broker will charge you a fee for this service. Alternatively, if you really only want one share for decoration, there are companies that specialize in selling shares of stock with certificates.  Two of them are giveashare.com and uniquestockgift.com, which offer one real share of stock with a stock certificate in certain popular companies.  (Note: I have no experience with either one.)  Some companies no longer issue new stock certificates; for those, these services sell you a replica stock certificate along with a real share of electronic stock.  (This is now the case for Disney and Apple.) With your stock certificate, you are an actual official stockholder, entitled to dividends and a vote at the shareholder meeting. If this is strictly an investment for you, consider the advantages of street name shares: As to your question on buying stock directly from a company and bypassing a broker altogether, see Can I buy stocks directly from a public company?" Yes. Private companies have shares, they're just not liquid and there may be restrictions around selling them; founders get shares when they found a company (not options), as do VCs that invest. An options pool is oftentimes created as a result of a VC financing (when the cap table is being carved up and the existing owners are being diluted, anyway) for the purposes of attracting future employees. You can purchase stock immediately in the open market on the day of the IPO when market opens. Below link gives you more information. http://finance.zacks.com/buy-ipo-stock-3903.html "Hmm... Well there are several ways to do that: Go to any bank (or at the very least major ones). They can assist you with buying and/or selling stocks/shares of any company on the financial market. They keep your shares safe at the bank and take care of them. The downside is that they will calculate fees for every single thing they do with your money or shares or whatever. Go to any Financial broker/trader that deals with the stock market. Open an account and tell them to buy shares from company ""X"" and keep them. Meaning they won't trade with them if this is what you want. Do the same as point 2, but on your own. Find a suitable broker with decent transaction fees, open an account, find the company's stock code and purchase the stocks via the platform the broker uses." "Shares sold to private investors are sold using private contracts and do not adhere to the same level of strict regulations as publicly traded shares. You may have different classes of shares in the company with different strings attached to them, depending on the deals made with the investors at the time. Since public cannot negotiate, the IPO prospectus is in fact the investment contract between the company and the public, and the requirements to what the company can put there are much stricter than private sales. Bob may not be able to sell his ""special"" stocks on the public exchange, as the IPO specifies which class of stock is being listed for trading, and Bob's is not the same class. He can sell it on the OTC market, which is less regulated, and then the buyer has to do his due diligence. Yes, OTC-sold stocks may have strings attached to them (for example a buy back option at a preset time and price)." "In the US, a private company with less than 500 owners can dictate who can or can't become a shareholder (this is true in general, but I'm sure there are loopholes).   Prior to Google's IPO I could not buy shares in Google at any price.   The reason Google was ""forced"" to go public is the 500 shareholder rule.   At a high level, with 500 shareholders the company is forced to do some extra financial accounting and they no longer can control who owns a share of the company, allowing me to purchase shares of google at that point.  At that point, it typically becomes in the companies best interest to go public. See this article about Google approaching the 500 shareholder limit in 2003. Further, Sorkin is not quite correct that ""securities laws mandate that the company go public"" if by ""go public"" we mean list on a stock exchange, available for general purchase.   Securities laws mandate what has to be reported in financial reporting and when you have to report it. Securities laws also can dictate restrictions on ownership of stock and if a company can impose their own restrictions. A group of investors cannot force a company onto a stock exchange.   If shares of Facebook are already for sale to anyone, then having >500 shareholders will force Facebook to file more paperwork with the SEC, it won't force Facebook onto the NYSE or NASDAQ.   When that point is reached, it may be in Facebook's best interest to have an IPO, but they will not be required by law to do so. Update:  CNN article discusses likely Facebook IPO in 2012. When companies have more than 500   shareholders, they're required to make   significant financial disclosures --   though they can choose to remain   private and keep their stock from   trading publicly. However, most   companies facing mandatory disclosures   opt to go public. The Securities and Exchange Commission   gives businesses lots of time to   prepare for that milestone. Companies   have until 120 days after the end of   the fiscal year in which they cross   the 500-shareholder line to begin   making their disclosures. If Facebook   tips the scale this year, that gives   it until April 2012 to start filing   financial reports." "No, assuming by ""public company"" you mean a corporation.  The shareholder's individual liability is limited to their investment.  Your shares can go to zero value, but that's the limit. EDIT In regard to the follow-up question in the comments: ""Are all companies in the stock market corporations?"" the answer is definitely ""no.""  I cannot say much about other countries, but the US markets have some entities which are known as ""master limited partnerships.""  These trade shares on the market by the usual rules, but if you buy you become a partner in the company rather than a shareholder.  You still have limited liability in this case, but there will be differences, for example, in how you're are taxed." By definition, an IPO'd stock is publicly traded, and you can buy shares if you wish. There's often an excitement on the first day that doesn't carry over to the next days or weeks.  The opening price may be well above the IPO price, depending on that demand. Yes, all the shares of a publicly traded company can be purchased. This effectively takes the company private so that it's no longer traded on a stock market. Here are some examples: EDIT: to answer your edited question... the corporation can issue more stock.  However that would dilute the value of existing shares.  Thus, existing shareholders must vote to allow more shares to be issued. So... in your situation yes, you'd need to wait for someone else to sell. No, you shouldn't buy it. The advice here is to keep any existing holdings but not make new purchases of the stock. how do they turn shares into cash that they can then use to grow their business? Once a Company issues an IPO or Follow-On Public Offer, the company gets the Money. Going over the list of question tagged IPO would help you with basics. Specifically the below questions; How does a company get money by going public in an IPO? Why would a company care about the price of its own shares in the stock market? Why would a stock opening price differ from the offering price?  From what I've read so far, it seems that pre-IPO an investment bank essentially buys the companies public shares, and that bank then sells them on the open market. Is the investment bank buying 100% of the newly issued public shares? And then depositing the cash equivalent into the companies bank account? Additionally, as the stock price rises and falls over the lifetime of the company how does that actually impact the companies bank balance? Quite a bit on above is incorrect. Please read the answers to the question tagged IPO. Once an IPO is over, the company does not gain anything directly from the change in shareprice. There is indirect gain / loss. Call the CBOE, the Chicago Board of Options Exchange I've requested options on several IPOs in the past. You mainly have to convince them that there is a market for them (or they won't be inclined to provide liquidity). The CBOE could talk to the company in question to help convince them, or the CBOE will just tell you when the options will begin trading. Oh yeah, sometimes they'll ask you who you work for, just try to avoid that question, they don't like to talk to individual/retail investors. You'd likely be subject to a lock-up period before you could sell the shares along with possibly having other rules about how you could sell your shares as you'd likely be seen as an insider that may have information that gives you an unfair advantage for selling the stock possibly. Depending on how far in advance you hold the shares, you may or may not have adjustments in the valuation and number of shares as some companies may do a split or reverse split when preparing for an IPO. A company I worked for in the late 1990s had an IPO and my stock options had a revised strike price because of a reverse stock split that was done prior to the IPO. 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.
