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."
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 The stock market is just like any other market, but stocks are bought and sold here. Just like you buy and sell your electronics at the electronics market, this is a place where buyers and sellers come together to buy and sell shares or stocks or equity, no matter what you call it. What are these shares?  A share is nothing but a portion of ownership of a company. Suppose a company has 100 shares issued to it, and you were sold 10 out of those, it literally means you are a 10% owner of the company. Why do companies sell shares? Companies sell shares to grow or expand. Suppose a business is manufacturing or producing and selling goods or services that are high in demand, the owners would want to take advantage of it and increase the production of his goods or services. And in order to increase production he would need money to buy land or equipment or labor, etc. Now either he could go get a loan by pledging something, or he could partner with someone who could give him money in exchange for some portion of the ownership of the company. This way, the owner gets the money to expand his business and make more profit, and the lender gets a portion of profit every time the company makes some. Now if the owner decides to sell shares rather than getting a loan, that's when the stock market comes into the picture. Why would a person want to trade stocks? First of all, please remember that stocks were never meant to be traded. You always invest in stocks. What's the difference? Trading is short term and investing is long term, in very simple language. It's the greed of humans which led to this concept of trading stocks. A person should only buy stocks if he believes in the business the company is doing and sees the potential of growth. Back to the question: a person would want to buy stocks of the company because: How does a stock market help society? Look around you for the answer to this question. Let me give you a start and I wish everyone reading this post to add at least one point to the answer. Corporations in general allow many people come together and invest in a business without fear that their investment will cause them undue liability - because shareholders are ultimately not liable for the actions of a corporation. The cornerstone North American case of how corporations add value is by allowing many investors to have put money towards the railroads that were built across America and Canada. For The stock market in particular, by making it easier to trade shares of a company once the company sells them, the number of people able to conveniently invest grows exponentially. This means that someone can buy shares in a company without needing to knock door to door in 5 years trying to find someone to sell to. Participating in the stock market creates 'liquidity', which is essentially the ease with which stocks are converted into cash. High liquidity reduces risk overall, and it means that those who want risk [because high risk often creates high reward] can buy shares, and those who want low risk [because say they are retiring and don't have a risk appetite anymore] can sell shares. Some brokers have a number of shares they can offer their customers, but the small guy will get 100, not as many as they'd like. In the Tech bubble of the late 90's I was able to buy in to many IPOs, but the written deal from the broker is that you could not sell for 30 days or you'd be restricted from IPO purchases for the next 90. No matter what the stock opened at, there were a fair number of stocks thay were below IPO issue price after 30 days had passed. I haven't started looking at IPOs since the tech flameout, but had I gotten in to LinkedIn it would have been at that $45 price. Let's see if it stays at these levels after 30 days.  Edit - This is the exact cut/paste from my broker's site :  Selling IPO Shares: While XXX customers are always free to sell shares purchased in a public offering at any time, short holding periods of less than 31 calendar days will be a factor in determining whether XXX allocates you shares in future public offerings. Accordingly, if you sell IPO shares purchased in a public offering within 30 calendar days of such purchase, you will be restricted from participating in initial and secondary public offerings through XXX for a period of 3 months.  (I deleted the broker name) I honestly don't know if I'd have gotten any LI shares. Next interesting one is Pandora. Is it correct that there is no limit on the length of the time that the company can keep the money raised from IPO of its stocks, unlike for the debt of the company where there is a limit? Yes that is correct, there is no limit. But a company can buy back its shares any time it wants. Anyone else can also buy shares on the market whenever they want. how does the trading company know which one I want to sell? It doesn't need to know. You just sell one. From taxation point of view depending on the country / tax jurisdiction, it can be only be FIFO or specific stock. In principle I agree with you. However the allegation is that the people managing the IPO withheld crucial information and informed insiders against investing. Maybe the allegations are false, but it should still be looked into. If the IPO shared crucial details with insider traders while keeping it from the public at large that would affect the investor's risk-assessment of a stock, that's insider trading and should be punished accordingly. "If so, then if company A never pays dividends to its shareholders, then what is the point of owning company A's stock? The stock itself can go up in price. This is not necessarily pure speculation either, the company could just reinvest the profits and grow. Since you own part of a company, your share would also increase in value. The company could also decide to start paying dividend. I think one rule of thumb is that growing companies won't pay out, since they reinvest all profit to grow even more, but very large companies like McDonalds or Microsoft who don't really have much room left to grow will pay dividends more. Surely the right to one vote for company A's Board can't be that valuable.  Actually, Google for instance neither pays dividend nor do you get to vote. Basically all you get for your money is partial ownership of the company. This still gives you the right to seize Google assets if you go bankrupt, if there's any asset left once the creditors are done (credit gets priority over equity). What is it that I'm missing? What you are missing is that the entire concept of the dividend is an illusion. There's little qualitative difference between a stock that pays dividend, and a stock that doesn't. If you were going to buy the stock, then hold it forever and collect dividend, you could get the same thing with a dividend-less stock by simply waiting for it to gain say 5% value, then sell 4.76% of your stock and call the cash your dividend. ""But wait,"" you say, ""that's not the same - my net worth has decreased!"" Guess what, stocks that do pay dividend usually do drop in value right after the pay out, and they drop by about the relative value of the dividend as well. Likewise, you could take a stock that does pay dividend, and make it look exactly like a non-paying stock by simply taking every dividend you get and buying more of the same stock with it. So from this simplistic point of view, it is irrelevant whether the stock itself pays dividend or not. There is always the same decision of whether to cut the goose or let it lay a few more eggs that every shareholder has to make it. Paying a dividend is essentially providing a different default choice, but makes little difference with regards to your choices. There is however more to it than simple return on investment arithmetic: As I said, the alternative to paying dividend is reinvesting profits back into the enterprise. If the company decided to pay out dividend, that means they think all the best investing is done, and they don't really have a particularly good idea for what to do with the extra money. Conversely, not paying is like management telling the shareholders, ""no we're not done, we're still building our business!"". So it can be a way of judging whether the company is concentrating on generating profit or growing itself. Needless to say the, the market is wild and unpredictable and not everyone obeys such assumptions. Furthermore, as I said, you can effectively overrule the decision by increasing or decreasing your position, regardless of whether they have decided to pay dividend to begin with. Lastly, there may be some subtle differences with regards to things like how the income is taxed and so on. These don't really have much to do with the market itself, but the bureaucracy tacked onto the market." "Not necessarily.  The abbreviation ""ESOP"" is ambiguous.  There are at least 8 variations I know of: You'll find references on Google to each of those, some more than others.  For fun you can even substitute the word ""Executive"" for ""Employee"" and I'm sure you'll find more.  Really. So you may be mistaken about the ""O"" referring to ""options"" and thereby implying it must be about options.  Or, you may be right.  If you participate in such a plan (or program) then check the documentation and then you'll know what it stands for, and how it works.  That being said: companies can have either kind of incentive plan: one that issues stock, or one that issues options, with the intent to eventually issue stock in exchange for the option exercise price. When options are issued, they usually do have an expiration date by which you need to exercise if you want to buy the shares. There may be other conditions attached. For instance, whether the plan is about stocks or options, often there is a vesting schedule that determines when you become eligible to buy or exercise. When you buy the shares, they may be registered directly in your name (you might get a fancy certificate), or they may be deposited in an account in your name. If the company is small and private, the former may be the case, and if public, the latter may be the case. Details vary. Check the plan's documentation and/or with its administrators."
