How is initial stock price (IPO) of a stock determined
Who determines company value at IPO? The Owners based on the advice from Lead Bankers and other Independent auditors who would determine the value of the company at the time of listing. At times instead of determining a fixed price a range is given [lower side and higher side]. The Market participants [FI / Institutional Investor Segments] then decide the price by bidding at an amount. There are multiple aspects in play that help stabalize the IPO and roles of various parties. A quick read of question with IPO tag is recommended Edits: Generally at a very broad level, one of the key purpose of the IPO is to either encash Owner equity [Owner wants some profits immediately] or Raise additional Capital. More often it is a mix of both. If the price is too low, one loose out on getting the true value, this would go to someone else. If the price is too high, then it may not attract enough buyers or even there are buyers, there is substantial -ve sentiment. This is not good for the company. Read the question From Facebook's perspective, was the fall in price after IPO actually an indication that it went well?  This puts determining the price of IPO more in the realm of art than science. There are various mechanism [Lead bankers, Institutional Investors, Underwriters] the a company would put in place to ensure the IPO is success and that itself would moderate the price to realistic level. More often the price is kept slightly lower to create a positive buzz about the stock.
"SELL -10 VERTICAL $IYR 100 AUG 09 32/34 CALL @.80 LMT 1) we are talking about options, these are a derivative product whose price is based on 6 variables. 2) options allow you to create risk out of thin air, and those risks come with shapes, and the only limit is your imagination (and how much your margin/borrowing costs are). Whereas a simple asset like the shares for $IYR only has a linear risk profile. stock goes up, you make money, stock goes down, you lose money, and that risk graph looks linear. a ""vertical"" has a nonlinear risk profile 3) a vertical is a type of ""spread"" that requires holding options that expire at the same time, but at different strike prices. 3b) This particular KIND of vertical is called a bear call spread (BCS). Since you are bearish (this makes money if the stock goes down, or stays in a very specific range) but are using calls which are a bullish options product. 4) -10 means you are selling the vertical. +10 means you are buying the vertical. A ""long"" vertical is initiated by buying an option closer to the money, and selling an option at a higher strike price. This would be +X A ""short"" vertical is initiated by selling an option closer to the money and buying an option at a higher strike price. The quantity would be -X 5) 32/34 stands for the strike prices. so you would be selling 10 call options at the 32 strike price, and buying 10 call options at the 34 strike price, both options expire in August 6) LMT stands for limit order, and $.80 is the limit order price that is desired. OPENING a vertical spread requires knowledge of options as well as how to send orders. MANAGING a vertical requires even more finesse, as you can ""leg-in"" and ""leg-out"" of spreads, without sending the entire order to the exchange floor at once. There is much to learn." In short, thanks to the answers and comments posted so far.  No actual money is magically disappeared when the stock price goes down but the value is lost. The value changes of a stock is similar to the value changes of a house. The following is the long answer I came up with based on the previous answers and comments alone with my own understandings. Any experts who find any of the following is 200% out of place and wrong, feel free to edit it or make comments. Everything below only applies if the following are true: The stock price is only decreasing since the IPO because the company has been spending the money but not making profits after the IPO. The devaluation of the stock is not the result of any bad news related to the company but a direct translation of the money the company has lost by spending on whatever the company is doing. The actual money don’t just disappear into the thin air when the stock price goes down. All the money involved in trading this stock has already distributed to the sellers of this stock before the price went down.  There is no actual money that is literally disappeared, it was shifted from one hand to another, but again this already happened before the price went down.   For example, I bought some stocks for $100, then the price went down to $80. The $100 has already shifted from my hand to the seller before the price went down. I got the stock with less value, but the actual money $100 did not just go down to $80, it’s in the hand of the seller who sold the stock to me.  Now if I sell the stock to the same seller who sold the stock to me, then I lost $20, where did the $20 go? it went to the seller who sold the stock to me and then bought it back at a lower price. The seller ended up with the same amount of the stocks and the $20 from me. Did the seller made $20? Yes, but did the seller’s total assets increased? No, it’s still $100, $80 from the stocks, and $20 in cash. Did anyone made an extra $20? No. Although I did lost $20, but the total cash involved is still there, I have the $80 , the seller who sold the stock to me and then bought it back has the $20. The total cash value is still $100. Directly, I did lost $20 to the guy who sold me the stock when the stock has higher value and then bought it back at a lower price. But that guy did not increased his total assets by $20. The value of the stock is decreased, the total money $100 did not disappear, it ended up from one person holding it to 2 people holding it. I lost $20 and nobody gained $20, how is that possible? Assume the company of the stock never made any profit since it’s IPO, the company just keeps spending the money, to really track down where the $20 I lost is going, it is the company has indirectly spent that money. So who got that $20 I lost? It could be the company spent $20 for a birthday cake, the $20 went to the cake maker. The company never did anything to make that $20 back, so that $20 is lost. Again, assume the stock price only goes down after  its IPO, then buying this stock is similar to the buying a sport car example from JoeTaxpayer (in one of the answers), and buying an apple example from BrenBarn(in one of the comments from JoeTaxpayer’s answer).  Go back to the question, does the money disappears into the thin air when the value of the stock goes down? No, the money did not disappear, it switched hands. It went from the buyer of the stock to the company, and the company has spent that money. Then what happens when the stock price goes down because bad news about the company? I believe the actual money still did not just disappear. If the bad news turn out to be true that the company had indeed lost this much money, the money did not disappear, it’s been spent/lost by the company. If the bad news turn out to be false, the stock price will eventually go up again, the money is still in the hand of the company. As a summary, the money itself did not disappear no matter what happens, it just went from one wallet to another wallet in many different ways through the things people created that has a value. "Well, this sub is generally pretty darn good. Among us are investment bankers, private equity analysts, valuation analysts, portfolio managers, traders, brokers, bachelors, masters, and doctorate students, etc. We're helpful, though sometimes snarky, and have an exceedingly low tolerance for bullshit.  I love it here.  And while your logic is sound, we can actually explore private equity directly, as while private and public equity are related, they are different enough to study separately, in my opinion.  Private equity deals with private companies. By definition, these investments are illiquid (they cannot be easily sold like public stocks), and unmarketable (there is no ready market to trade these investments, like stock). They are generally held for longer time periods.  At its earliest stage, private equity is synonymous with ""initial investment"" or ""seed funding."" This includes (if we are maybe slightly liberal with our definition), the initial investment an entrepreneur makes into his business. At this stage, friends and family, angel investors and venture capital are present. At different points of a company lifecycle, different financiers become interested/applicable (mezzanine investors, etc.).  The investment made into a company allocates a certain percentage of the ownership of the company to the investor in exchange for cash (usually). This cash is used to cover expenses and take on capital projects. The goal of these investments is to directly make the company (and its value, and thus the investor's value) grow.   At some points in time, a new investor will show up and either invest directly in the company (same as before) or buy another investor's holding in the company (in which case, cash goes to *that specific investor* and *not* the company).   At every stage of investment leading up to IPO, the deals are negotiated between the parties. The results of a given negotiation determines the value of that company's equity. For example, if I pay you $100 for 50% of your company, the company's implied worth is $200. If two days later, Joe comes and offers to buy 33% of the company for $100, the Company is worth $300. (Special note: these percentages are assumed to be the allocation of equity **after** the deal. In this last case, the ownership of your company would be 33% you, 33% me, and 33% Joe. This illustrates something called *dilution,* which is very important to investors as it effects their eventual potential payoff later down the road, along with some other things).   At this point, do you have any questions?" "Yes it is possible, as long as the broker you use allows conditional orders. I use CMC Markets in Australia, and they allow free conditional orders either when initially placing a buy order or after already buying a stock. See the Place New Order box below:  Once you have selected a stock to buy, the number of shares you want to buy and at what price you can place up to 3 conditional orders. The first condition is a ""Place order if..."" conditional order. Here you can place a condition that your buy order will only be placed onto the market if that condition is met first.  Say the stock last traded at $9.80 and you only want to place your order the next day if the stock price moves above the current resistance at $10.00. So you would Place order if Price is at or above $10.00. So if the next day the price moves up to $10 or above your order will be placed onto the market. The second condition is a ""Stop loss"" conditional order. Here you place the price you want to sell at if the price drops to or past your stop loss price. It will only be placed on to the market if your buy order gets traded. So if you wanted to place your stop loss at $9.00, you would type in 9.00 in the box after ""If at or below ?"" and select if you want a limit or market order. The third condition is a ""Take profit"" conditional order. This allows you to take profits if the stock reaches a certain price. Say you wanted to take profits at 50%, that is if the price reached $15.00. So you would type in 15.00 in the box after ""If at or above ?"" and again select if you want a limit or market order. These conditional orders can all be placed at the time you enter your buy order and can be edited or deleted at any time. The broker you use may have a different process for entering conditional orders, and some brokers may have many more conditional orders than these three, so investigate what is out there and if you are confused in how to use the orders with your broker, simply ask them for a demonstration in how to use them." Let's say the company has a million shares valued at $10 each, so market caps is $10 million dollar = $10 per share. Actual value of the company is unknown, but should be close to that $10 million if the shares are not overvalued or undervalued.  If they issue 100,000 more shares at $10 each, the buyers pay a million dollar. Which goes into the bank account of the company. Which is now worth a million dollar more than before. Again, we don't know what it is worth, but the market caps should go up to $11 million dollar. And since you have now 1,100,000 shares, it's still $10 per share.  If the shares are sold below or above $10, then the share price should go down or up a bit. Worst case, if the company needs money, can't get a loan, and sells 200,000 shares for $5 each to raise a million dollars, there will be suspicion that the company is in trouble, and that will affect the share price negatively. And of course the share price should have dropped anyway because the new value is $11,000,000 for $1,200,000 shares or $9.17 per share. That's the problem with IPOs. Professionals are very bad at valuing companies, particularly prospectively. That's Daniel Kahneman's whole point about how no one beats the market. Yet, we expect the same types of professionals who can't beat the market to set the price for the market. Stock price = Earning per share * P/E Ratio. Most of the time you will see in a listing the Stock price and the P/E ration. The calculation of the EPS is left as an exercise for the student Investor. I think you're looking for the public float: Public float or the unqualified term may also refer to the number of   outstanding shares in the hands of public investors as opposed to   company officers, directors, or controlling-interest investors.   Assuming the insider held shares are not traded, these shares are the   publicly traded ones. The float is calculated by subtracting   restricted shares from outstanding shares. As mentioned, Treasury stock is probably the most narrow definition of restricted stock (not publicly traded), but shares held by corporate officers or majority investors are often included in the definition as well. In any case, the balance sheet is indeed a good place to start.
