What exactly changes following a stock split? Why doesn't “Shares” (on the following SEC balance sheet) change?
In theory*, if a company has 1m shares at $10 and does a 10 for 1 split, then the day after it has 10m shares at $1 (assuming no market move). So both the price and the number of share change, keeping the total value of the company unchanged. Regarding your BIS, I suspect that the new number of shares has not been reported yet because it's an ETF (the number of shares in issue changes everyday due to in/out flows). Your TWX example is not ideal either because there was a spin off on the same day as the stock split so you need to separate the two effects. * Some studies have documented a positive stock split effect - one of the suggested reasons is that the stock becomes more liquid after the split. But other studies have rejected that conclusion, so you can probably safely consider that on average it will not have a material effect.
Because the stock still has the same value as the money paid for it - you are just exchanging one asset for another (of course the stock value starts to change immediately, but for the accounting the fictional value is the buying price). For the accounting, it is similar to changing a 100$ bill in five 20$ bills - same value, still assets. Is it normal for such transactions to create new outstanding shares? Yes a company can create new shares or a Majority share holder can sell some of his stake or it can be a mix of both. how will this news affect the short-term and long-term price of the company's stock? This is opinion based and not apt for this site. It can be positive or negative depending on how the market reacts to the news. Well, if one share cost $100 and the company needs to raise $10000, then the company will issue 100 shares for that price.  Right? However, say there's 100 shares out there now, then each share holder owns 1/100th of the company. Now the company will remain the same, but it's shared between 200 shareholders after the issuing of new shares.  That means each share holder now owns 1/200th of the company.  And hence only gets 1/200th of their earnings etc. Yes, there is a delay between when you buy a stock and when you actually take ownership of it.  This is called the settlement period. The settlement period for US equities is T+2 (other markets have different settlement periods), meaning you don't actually become a shareholder of record until 2 business days after you buy.  Conversely, you don't stop being a shareholder of record until 2 business days after you sell. Presumably at some point in the (far) future all public markets will move to same-day changes of ownership, at which point companies will stop making announcements of the form all shareholders of record as of September 22nd and will switch to announcements of the form all shareholders of record as of September 22nd at 13:00 UTC 1) Explicitly, how a company's share price in the secondary market affects the company's operations. (Simply: How does it matter to a company that its share price drops?) I have a vague idea of the answer, but I'd like to see someone cover it in detail.  2) Negative yield curves, or bonds/bills with negative yields  Thanks! If the company went bankrupt, the issued public shares that were outstanding at the time most likely were voided, in which case your shares are most definitely gone.  The company might have done a new stock issuance coming out of bankruptcy with a different symbol, and while it could be substantially the same company, it doesn't mean much for you.  It's unfortunate this may be the case, but it is one of the risks of investing. "Note that these used to be a single ""common"" share that has ""split"" (actually a ""special dividend"" but effectively a split). If you owned one share of Google before the split, you had one share giving you X worth of equity in the company and 1 vote. After the split you have two shares giving you the same X worth of equity and 1 vote. In other words, zero change. Buy or sell either depending on how much you value the vote and how much you think others will pay (or not) for that vote in the future.  As Google issues new shares, it'll likely issue more of the new non-voting shares meaning dilution of equity but not dilution of voting power. For most of us, our few votes count for nothing so evaluate this as you will.  Google's founders believe they can do a better job running the company long-term when there are fewer pressures from outside holders who may have only short-term interests in mind. If you disagree, or if you are only interested in the short-term, you probably shouldn't be an owner of Google. As always, evaluate the facts for yourself, your situation, and your beliefs." "What benefit do I get from buying a share The value of any financial asset is its ability to generate cash in the future, and thus the ""value"" of a share is heavily influenced by the dividends it pays and the equity value.  The equity value can be calculated different ways. Two common ways are to just take ""book"" value, meaning assets - liabilities, or you can look at the projected free cash flows of the company discounted back to the present time. Voting rights don't typically influence a share price except in hostile takeover scenarios (meaning someone buys up a lot of shares to have more influence in company decisions)" In simplest terms, when a company creates new shares and sells them, it's true that existing shareholders now own a smaller percentage of the company.  However, as the company is now more valuable (since it made money by selling the new shares), the real dollar value of the previous shares is unchanged. That said, the decision to issue new shares can be interpreted by investors as a signal of the company's strategy and thereby alter the market price;  this may well affect the real dollar value of the previous shares.  But the simple act of creating new shares does not alter the value in and of itself. Most corporations have a limit on the number of shares that they can issue, which is written into their corporate charter.  They usually sell a number that is fewer than the maximum authorized number so that they have a reserve for secondary offerings, employee incentives, etc. In a scrip dividend, the company is distributing authorized shares that were not previously issued.  This reduces the number of shares that it has to sell in the future to raise capital, so it reduces the assets of the company. In a split, every share (including the authorized shares that haven't been distributed) are divided.  This results in more total shares (which then trade at a price that's roughly proportional to the split), but it does not reduce the assets of the company. Shares often come associated with a set of rights, such as ability to vote in the outcome of the company. Some shares do not have this right, however. With your ability to vote in the outcome of the company, you could help dictate that the company paid dividends at a point in time. Or many other varieties of outcomes. Also, if there were any liquidity events due to demand of the shares, this is typically at a much higher price than the shares are now when the company is private/closely held. It seems like you want to compare the company's values not necessarily the stock price.  Why not get the total outstanding shares and the stock price, generate the market cap.  Then you could compare changes to market cap rather than just share price. A stock dividend isn't exactly a split. Example: You have 100 shares of stock worth $5 a share (total value $500). The company wants to distribute a dividend worth 1%. You could expect a check for $5. But If they wanted to do a stock dividend they could send you 0.01 shares for every share you own, in your case you will be given a single share worth $5. Now you own 101 shares. Why a share dividend? It doesn't take cash to give the dividend. It keeps the money invested in the company. Some investors re-invest a cash dividend, some don't.  A cash dividend is generally taxable income for the investor; a stock dividend isn't. Some investors prefer one over the other, but it depends on their specific financial picture. Neither a stock dividend, a cash dividend or split changes anything.  The split changes the price to meet a goal. The cash dividend lowers the price by sending excess cash to the investors. The stock dividend lowers the price by creating new shares and retaining cash.  It company picks the message and the method. depending on their goals and situation. Remember that a company may want to give a dividend because they have a history of doing so, but not have the cash to do so. It is like a split because the number of shares you own will go up, and the price per share will go down. But a split is generally done to bring the price of a share to within a specific range. The company sees a benefit to having a stock mid priced, instead of very high or very low. Your question is missing information. The most probable reason is that the company made a split or a dividend paid in stock and that you might be confusing your historical price (which is relevant for tax purposes) with your actual market price. It is VERY important to understand this concepts before trading stocks. Firstly a stock split is easy, for example each unit of stock is converted into 10 units.  So if you owned 1% of the company before the stock split, you will still own 1% after the stock split, but have 10 times the number of shares.   The company does not pay out any money when doing this and there is no effect on tax for the company or the share holder. Now onto stock dividend… When a company make a profit, the company gives some of the profit to the share holders as a dividend; this is normally paid in cash.  An investor may then wish to buy more shares in the company using the money from the dividend.      However buying shares used to have a large cost in broker charges etc. Therefore some companies allowed share holders to choose to have the dividend paid as shares.   The company buys enough of their own shares to cover the payout, only having one set of broker charges and then sends the correct number of shares to each share holder that has opted for a stock dividend.  (Along with any cash that was not enough to buy a complete share.) This made since when you had paper shares and admin costs where high for stock brokers.   It does not make sense these days. A stock dividend is taxed as if you had been paid the dividend in cash and then brought the stock yourself.
