Can I buy IPO stock during the pre-market trading on the day of IPO?
The first moment of trading usually occurs even later than that. It may take a few hours to balance the current buy/sell orders and open the stock. Watch CNBC when a hot IPO is about to open and you'll see the process in real time. If you miss it, look at a one day Yahoo chart to see when the open occurred.
The best thing to do is not worry about what time is best to buy but put in a conditional order before the market opens. If your conditions are met during the trading day your order will go through and you will buy the shares. This keeps your emotions out of your trading and will stop you from either chasing the market or buying when you consider the wrong time. As you have already done your analysis and made your decision before market open, thus you should place your conditional orders and stop losses before market opens as well. "In a sense, yes. There's a view in Yahoo Finance that looks like this   For this particular stock, a market order for 3000 shares (not even $4000, this is a reasonably small figure) will move the stock past $1.34, more than a 3% move.  Say, on the Ask side there are 100,000 shares, all with $10 ask. It would take a lot of orders to purchase all these shares, so for a while, the price may stay right at $10, or a bit lower if there are those willing to sell lower.  But, say that side showed $10 1000, $10.25 500, $10.50 1000. Now, the volume is so low that if I decided I wanted shares at any price, my order, a market order will actually drive the market price right up to $10.50 if I buy 2500 shares ""market"".  You see, however, even though I'm a small trader, I drove the price up. But now that the price is $10.50 when I go to sell all 2500 at $10.50, there are no bids to pay that much, so the price the next trade will occur at isn't known yet. There may be bids at $10, with asking (me) at $10.50. No trades will happen until a seller takes the $10 bid or other buyers and sellers come in." Yes, an investment can be made in a company before IPO. The valuation process is similar as that done for arriving at IPO or for a normal listed company. The difference may be the premium perceived for the idea in question. This would differ from one investor to other. For example, whether Facebook will be able to grow at the rate and generate enough revenues and win against competition is all a mathematical model based on projections. There are quite a few times the projection would go wrong, and quite a few times it would go correct. An individual investor cannot generally borrow from banks to invest into a company (listed or otherwise) (or for any other purpose) if he does not have any collateral that can be kept as security by the bank. An individual can get a loan only if he has sufficient collateral. The exceptions being small personal loans depending on one's credit history. The Private Equity placement arm of banks or firms in the business of private equity invest in start-up and most of the time make an educated guess based on their experience. More than half of their investments into start-ups end up as wiped out. An occasional one or two companies are ones that they make a windfall gain on. "IPO's are priced so that there's a pop"" on the opening day."" If I were IPOing my company and the price ""popped"" on the open, I would think the underwriter priced it too low. In fact if I were to IPO, I'd seek an underwriter whose offerings consistently traded on the first day pretty unchanged. That means they priced it correctly. In the 90's IPO boom, there were stocks that opened up 3X and more. The original owners must have been pretty upset as the poor pricing guidance the underwriter offered." Not that I am aware. There are times that an option is available, but none have traded yet, and it takes a request to get a bid/ask, or you can make an offer and see if it's accepted. But the option chain itself has to be open. The stock tends to drop by the amount of the dividend -- or if you prefer to think of it this way, the stock price has been pushed up by the amount of the dividend before it was paid out. Really, all this shift does is factor out the impending dividend's effect on the real purchase cost of the stock. As such it's pretty much irrelevant except that, of course, the dividend is short-term gain that you have to pay taxes on almost immediately. Which also tends to get figured into the price folks are willing to pay for the stock. Conclusion: no, there's no real opportunity here. There's a slight tax reason to avoid buying right before dividends are paid, but that's about it. Basic principle: If it's simple and obvious,the market has already accounted for it. "You are probably going to hate my answer, but... If there was an easy way to ID stocks like FB that were going to do what FB did, then those stocks wouldn't exist and do that because they would be priced higher at the IPO. The fact is there is always some doubt, no one knows the future, and sometimes value only becomes clear with time. Everyone wants to buy a stock before it rises right? It will only be worth a rise if it makes more profit though, and once it is established as making more profit the price will be already up, because why wouldn't it be? That means to buy a real winner you have to buy before it is completely obvious to everyone that it is going to make more profit in the future, and that means stock prices trade at speculative prices, based on expected future performance, not current or past performance. Now I'm not saying past and future performance has nothing in common, but there is a reason that a thousand financially oriented websites quote a disclaimer like ""past performance is not necessarily a guide to future performance"". Now maybe this is sort of obvious, but looking at your image, excluding things like market capital that you've not restricted, the PE ratio is based on CURRENT price and PAST earnings, the dividend yield is based on PAST publications of what the dividend will be and CURRENT price, the price to book is based on PAST publication of the company balance sheet and CURRENT price, the EPS is based on PAST earnings and the published number of shares, and the ROI and net profit margin in based on published PAST profits and earnings and costs and number of shares. So it must be understood that every criteria chosen is PAST data that analysts have been looking at for a lot longer than you have with a lot more additional information and experience with it. The only information that is even CURRENT is the price. Thus, my ultimate conclusive point is, you can't based your stock picks on criteria like this because it's based on past information and current stock price, and the current stock price is based on the markets opinion of relative future performance. The only way to make a good stock pick is understand the business, understand its market, and possibly understand world economics as it pertains to that market and business. You can use various criteria as an initial filter to find companies and investigate them, but which criteria you use is entirely your preference. You might invest only in profitable companies (ones that make money and probably pay regular dividends), thus excluding something like an oil exploration company, which will just lose money, and lose it, and lose some more, forever... unless it hits the jackpot, in which case you might suddenly find yourself sitting on a huge profit. It's a question of risk and preference. Regarding your concern for false data. Google defines the Return on investment (TTM) (%) as: Trailing twelve month Income after taxes divided by the average (Total Long-Term Debt + Long-Term Liabilities + Shareholders Equity), expressed as a percentage. If you really think they have it wrong you could contact them, but it's probably correct for whatever past data or last annual financial results it's based on." Publicly traded companies perform dilution via an FPO (Follow-up Public Offer). It is a process similar to IPO, with announcements, prospectus, etc. You will know ahead of time when that happen. Stocks traded OTC are not required to file a lot of regulatory documents that publicly traded stocks are required to file, and may not disclose dilutions or additional issues. By buying OTC you agree to these terms. You will probably get a notice and a chance to vote on that in your proxy statement, but that happens when you already own the stock. "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." You can check whether the company whose stock you want to buy is present on an european market. For instance this is the case for Apple at Frankfurt. "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?" "There are no ""rules"" about how the price should act after an IPO, so there are no guarantee that a ""pop"" would appear at the opening day. But when an IPO is done, it's typically underpriced. On average, the shares are 10% up at the end of the first day after the IPO (I don't have the source that, I just remember that from some finance course). Also, after the IPO, the underwriter can be asked to support the trading of the share for a certain period of time. That is the so called stabilizing agent. They have few obligations like: This price support in often done by a repurchase of some of the shares of poorly performing IPO. EDIT: Informations about the overallotment pool. When the IPO is done, a certain number of client buy the shares issued by the company. The underwriter, with the clients, can decide to create an overallotment pool, where the clients would get a little more shares (hence ""overallotment""), but this time the shares are not issued by the company but by the underwriter. To put it another way, the underwriter oversell and becomes short by a certain number of shares (limited to 15% of the IPO). In exchange for the risk taken by this overallotment, the underwriter gets a greenshoe option from the clients, that will allows the underwriter to buy back the oversold shares, at the price of the IPO, from the clients. The idea behind this option is to avoid a market exposure for the underwriter. So, after the IPO: If the price goes down, the underwriter buys back on the market the overshorted shares and makes a profits. If the price goes up, the company exercise the greenshoe option buy the shares at the IPO prices (throught the overallotment pool, that is, the additional shares that the clients wanted ) to avoid suffering a loss." "I have an account with ETrade. Earlier this week I got an offer to participate in the IPO proper (at the IPO price). If Charles Schwab doesn't give you the opportunity, that's a shortcoming of them as a brokerage firm; there are definitely ways for retail investors to invest in it, wise investment or no. (Okay, technically it wasn't an offer to participate, it was a notice that participation was possibly available, various securities-law disclaimers etc withstanding. ""This Web site is neither an offer to sell nor a solicitation to buy these securities. The offer is by prospectus only. This Web site contains a preliminary prospectus for each offering."" etc etc)." I didn't say only the IPO I just said public offerings. Trades between secondary investors would be taxed at a higher level. I also understand the difference between loaning money to a company and investing in equity.  Personally I think that loans are underused in today's investment world because people are too focused on getting the most out of the few big winners. Investment banks don't have to buy anything. If they don't think the stock is worth buying - they won't. If they think it is - others on the secondary market will probably think so too. Initial public offering is offering to the public - i.e.: theoretically anyone can participate and purchase stocks. The major investment firms are not buying the stocks for themselves - but for their clients who are participating in this IPO. I, for example, receive email notifications from my brokerage firm each time there's another IPO that they have access to, and I can ask the brokerage to buy stocks from the IPO on my behalf. When that happens - they don't buy the stocks themselves and then sell to me. No, what happens is that I buy a stock, through them, and they charge me a commission for the service. Usually IPO participation commissions are higher than regular trading commissions. Most of the time those who purchase stocks at IPO are institutional investors - i.e.: mutual funds, pension plans, investment banks for their managed accounts, etc. Retail investors would probably not participate in the IPO because of the costs, limited access (not all the brokerage firms have access to all the IPOs), and the uncertainty, and rather purchase the stocks later on a secondary market.
