How Is the Price of a Stock Determined? [duplicate]
"The market price of a stock is based on nothing at all more than what two parties were last willing to transact for it. The stock has a ""bid"" and an ""ask"" each is the value placed by a counterparty. For the sale to occur, one party must meet the other. The stock transacts and that is the price. For a stock to ""go up"" people must be willing to pay more for it. Likewise, for it to ""go down"" people must be willing to accept less for it."
I stock is only worth what someone will pay for it.  If you want to sell it you will get market price which is the bid. "If there is a very sudden and large collapse in the exchange rate then because algorithmic trades will operate very fast it is possible to determine “x” immediately after the change in exchange rate. All you need to know is the order book. You also need to assume that the algorithmic bot operates faster than all other market participants so that the order book doesn’t change except for those trades executed by the bot. The temporarily cheaper price in the weakened currency market will rise and the temporarily dearer price in the strengthened currency market will fall until the prices are related by the new exchange rate. This price is determined by the condition that the total volume of buys in the cheaper market is equal to the total volume of sells in the dearer market.   Suppose initially gold is worth $1200 on NYSE or £720 on LSE. Then suppose the exchange rate falls from r=0.6 £/$ to s=0.4 £/$.  To illustrate the answer lets assume that before the currency collapse the order book for gold on the LSE and NYSE looks like: GOLD-NYSE   Sell (100 @ $1310) Sell (100 @ $1300) <——— Sell (100 @ $1280) Sell (200 @ $1260) Sell (300 @ $1220) Sell (100 @ $1200) ————————— buy (100 @ $1190) buy (100 @ $1180)   GOLD-LSE Sell (100 @ £750) Sell (100 @ £740) ————————— buy (200 @ £720) buy (200 @ £700) buy (100 @ £600) buy (100 @ £550) buy (100 @ £530) buy (100 @ £520) <——— buy (100 @ £500)   From this hypothetical example, the automatic traders will buy up the NYSE gold and sell the LSE gold in equal volume until the price ratio ""s"" is attained. By summing up the sell volumes on the NYSE and the buy volumes on the LSE, we see that the conditions are met when the price is $1300 and £520. Note 800 units were bought and sold.   So “x” depends on the available orders in the order book. Immediately after this, however, the price of the asset will be subject to the new changes of preference by the market participants. However, the price calculated above must be the initial price, since otherwise an arbitrage opportunity would exist." There is no direct relationship between volume and stock price. High volume indicates how much stock is changing hands. That can be because people are enthusiastically buying OR enthusiastically selling... and their reasons for doing so may not agree with your own sense of the future value of the stock. Higher volume may mean that the price is more likely to change during the day, but it can be in either direction -- or in no direction at all if there isn't a general agreement on how to react to some piece of news. It's a possibly interesting datum, but it means nothing in isolation. "Here is how I would approach that problem: 1) Find the average ratios of the competitors: 2) Find the earnings and book value per share of Hawaiian 3) Multiply the EPB and BVPS by the average ratios. Note that you get two very different numbers.  This illustrates why pricing from ratios is inexact.  How you use those answers to estimate a ""price"" is up to you.  You can take the higher of the two, the average, the P/E result since you have more data points, or whatever other method you feel you can justify.   There is no ""right"" answer since no one can accurately predict the future price of any stock." The same as when you are buying a car. If a dealer quotes 10k and you quote 8k. 8k is the buy price and 10k is the sell price.  Somebody might quote 8.5k and another dealer might quote 9.5k. The the new price that you see on your screen is 8.5k(Best buy price) and 9.5k(Best sell price). When the buyer and seller agree to an amount, the car(In your case stock) is traded. "Stock prices are set by bidding. In principle, a seller will say, ""I want $80."" If he can't find anyone willing to buy at that price, he'll either decide not to sell after all, or he'll lower his price. Likewise, a buyer will say, ""I'll pay $70."" If he can't find anyone willing to pay that price, he'll either decide not to buy or he'll increase his price. For most stocks there are many buyers and many sellers all the time, so there's a constant interplay. The typical small investor has VERY little control of the price. You say, ""I want to buy 10 shares of XYZ Corporation and my maximum price is $20."" If the current trending price is below $20, your broker will buy it for you. If not, he won't. You normally have some time limit on the order, so if the price falls within your range within that time period, your broker will buy. That is, your choice is basically to buy or not buy, or sell or not sell, at the current price. You have little opportunity to really negotiate a better price. If you have a significant percentage of a company's total stock, different story. In real life, most stocks are being traded constantly, so buyers and sellers both have a pretty good idea of the current price. If the last sale was ten minutes ago for $20, it's unlikely anyone's going to now bid $100. They're going to bid $20.50 or $19.25 or some such. If the last sale was for $20 and your broker really came to the floor and offered to buy for $100, I suppose someone would sell to him very quickly before he realized what an outrageous price this was. I use TD Ameritrade, and on their web site, if I give a price limit on a buy that's more than a small percentage above the last sale, they reject it as an error. I forget the exact number but they won't even accept a bid of $80 if the stock is going for $40. They might accept $41 or $42, something like that." The literal answer to your question 'what determines the price of an ETF' is 'the market'; it is whatever price a buyer is willing to pay and a seller is willing to accept. But if the market price of an ETF share deviates significantly from its NAV, the per-share market value of the securities in its portfolio, then an Authorized Participant can make an arbitrage profit by a transaction (creation or redemption) that pushes the market price toward NAV. Thus as long as the markets are operating and the APs don't vanish in a puff of smoke we can expect price will track NAV. That reduces your question to: why does NAV = market value of the holdings underlying a bond ETF share decrease when the market interest rate rises?  Let's consider an example. I'll use US Treasuries because they have very active markets, are treated as risk-free (although that can be debated), and excluding special cases like TIPS and strips are almost perfectly fungible. And I use round numbers for convenience. Let's assume the current market interest rate is 2% and 'Spindoctor 10-year Treasury Fund' opens for business with $100m invested (via APs) in 10-year T-notes with 2% coupon at par and 1m shares issued that are worth $100 each. Now assume the interest rate goes up to 3% (this is an example NOT A PREDICTION); no one wants to pay par for a 2% bond when they can get 3% elsewhere, so its value goes down to about 0.9 of par (not exactly due to the way the arithmetic works but close enough) and Spindoctor shares similarly slide to $90. At this price an investor gets slightly over 2% (coupon*face/basis) plus approximately 1% amortized capital gain (slightly less due to time value) per year so it's competitive with a 3% coupon at par.  As you say new bonds are available that pay 3%. But our fund doesn't hold them; we hold old bonds with a face value of $100m but a market value of only $90m. If we sell those bonds now and buy 3% bonds to (try to) replace them, we only get $90m par value of 3% bonds, so now our fund is paying a competitive 3% but NAV is still only $90.  At the other extreme, say we hold the 2% bonds to maturity, paying out only 2% interest but letting our NAV increase as the remaining term (duration) and thus discount of the bonds decreases -- assuming the market interest rate doesn't change again, which for 10 years is probably unrealistic (ignoring 2009-2016!). At the end of 10 years the 2% bonds are redeemed at par and our NAV is back to $100 -- but from the investor's point of view they've forgone $10 in interest they could have received from an alternative investment over those 10 years, which is effectively an additional investment, so the original share price of $90 was correct. The indication is based on the average Buy-Hold-Sell rating of a group of fundamental analysts. The individual analysts provide a Buy, Hold or Sell recommendation based on where the current price of the stock is compared to the perceived value of the stock by the analyst.  Note that this perceived value is based on many assumptions by the analyst and their biased view of the stock. That is why different fundamental analysts provide different values and different recommendations on the same stock. So basically if the stock's price is below the analyst's perceived value it will be given a Buy recommendation, if the price is equal with the perceived value it will be given a Hold recommendation and if the price is more than the perceived value it will be given a Sell recommendation. As the others have said this information IMHO is useless. "Stock price is determined by the buyers and sellers, correct? Correct! ""Everything is worth what its purchaser will pay for it""-Publius Syrus What causes people to buy or sell? Is it news? earnings? stock analysis and techniques? All of these things influence investors' perception of how much a stock is worth. If AMZN makes a lot of money one quarter, then the price might go up. But maybe public perception of AMZN changes because of a large scandal. This could cause the share price to decline even with the favorable earnings report. Why do these 'good' or 'bad' news make people want to buy/sell a stock? People invest to make money. If it looks like a company is going to take a turn for the worst, people will sell. If it looks like the company has a bright, cash-laden future in front of them, people will buy. News is one of the many factors people use to determine how well a company will do. Theoretically could a bunch of people short AMZN and drive down the price regardless of how well it is doing? Say investors wanted to boycott AMZN in order to drive down the cost and get some cheap shares. This is pretty silly, but say for the sake of the argument that everyone who owned AMZN decided to sell their shares and no other investor was willing to buy the shares for less than $0.01, then AMZN shares would be ""worth"" $0.01 in that aspect. That is extremely unlikely to happen, though, for two reasons:" "Stocks prices are determined whenever a buyer and seller agree to trade at a given price. The company (you use AAPL as an example) doesn't set its own stock price. Rather, the investors set the price every time it trades. There's no ""official"" price -- just the last trade. Likewise, you can offer to trade a stock at whatever price you want: that's the definition of a limit order. You might not find a willing buyer or seller at that price, but you can certainly open an order. Stock quotes that you get from your broker or a finance web site reflect the price as last traded. These quotes are updated throughout the trading day and the frequency and delay varies amongst quote providers. Like Knuckle-Dragger suggests in the comments, there are ways to get real-time quotes. It's often more helpful to think in terms of bid/ask instead of ""official price"". See this question for details." I was thinking that the value of the stock is the value of the stock...the actual number of shares really doesn't matter, but I'm not sure. You're correct.  Share price is meaningless.   Google is $700 per share, Apple is $100 per share, that doesn't say anything about either company and/or whether or not one is a better investment over the other. You should not evaluate an investment decision on price of a share.  Look at the books decide if the company is worth owning, then decide if it's worth owning at it's current price. "The fallacy in your question is in this statement: ""The formulas must exist, because prices can be followed real time."" What you see are snapshots of the current status of the stock, what was the last price a stock was traded at, what is the volume, is the price going up or down.  People who buy and hold their stock look at the status every few days or even every few months. Day traders look at the status every second of the trading day.  The math/formula comes in when people try to predict where the stock is going based on the squiggles in the line. These squiggles move based on how other people react to the squiggles.  The big movements occur when big pieces of news make large movements in the price. Company X announces the release of the key product will be delayed by a year; the founder is stepping down; the government just doubled the order for a new weapon system; the insiders are selling all the shares they can. There are no formulas to determine the correct price, only formulas that try to predict where the price may go." As yet another explanation of why it does not really matter, you can look at this from the valuation point of view. Stock price is the present value of its future cash flows (be it free cash flow of the firm or dividends, depending on the model). Let's have a look at the dividends case. Imagine, the price of the stock is based on only three dividends streams $5 dollars each: dividend to be paid today, in year 1, and in year 2. Each should be discounted back to today (say, at 10%), except today's dividend, since today is now.  Once that dividend is paid, it is no longer in the stream of cash flows. So if we just delete that first $5 from the formula, the price will adjust itself down by the amount of the dividend to $8.68. NOTE that this is a very simple example, since in reality cash flows streams are arguably infinite and because there are many other factors affecting stock price. But simply for your understanding, this example should provide you with the reason simply from the valuation perspective. It's still the purchase price or the price at which the shares are purchased or granted. This Investopedia article describes how the price is used for tax purposes: The amount that must be declared [for tax purposes] is determined by subtracting the original purchase or exercise price of the stock (which may be zero) from the fair market value of the stock as of the date that the stock becomes fully vested. Restricted stock awards are similar to stock options. The employer promises to grant the employee a certain number of shares upon the completion of the vesting schedule. The price at which the shares are purchased (or granted, if the price is zero) is the exercise price. The RDFI (Receiving Depository Institution) is the place where you keep your money and where the Debit is going to be made. Unfortunately the Debit did not go through for some kind of regulatory reason that I don't understand. You could ask them why people are not allowed to make ACH Debits there or you can try to pay through a different bank.
