When a stock price rises, does the company get more money?
Not directly. But companies benefit in various ways from a higher stock price. One way a high stock price can hurt a company is that many companies do share buybacks when the price is too high. Economically speaking, a company should only buy back shares when those shares are undervalued. But, management may have incentives to do buybacks at irrationally high prices. No. Not directly. A company issues stock in order to raise capital for building its business. Once the initial shares are sold to the public, the company doesn't receive additional funds from future transactions of those shares of stock between the public.  However, the company could issue more shares at the new higher price to raise more capital. "Seems like no one in this thread has heard of ""treasury stocks"", which indeed allow a company to own and sell its own stock. Think about it. When there is a stock buy-back funded by excess profits, where does that stock go?" When a stock price rises, the company's assets are worth more. This doesn't mean it gets more cash directly, but it can liquidate (= sell) some of its stocks for a higher return than before.
Fully Paid up Partly Paid up: A company may issue stock to you which is only partly paid up, for example, a company may issue a stock of face value 10 to you and ask you to pay 5 now and other 5 will be adjusted later by some other mechanism. This stock shall be partly paid up. Usually, these stocks are issued in different circumstances, for example as part payment for debentures, preference shares or other capital structuring. On the other hand for a fully paid up share no more money needs to be paid by you or no other adjustments need to be made. So, above, the company is issuing you with stocks for which you will need to pay no further money, they are fully paid for. Authorized Capital: Authorized capital of a company is the amount of money a company can raise by selling stock (not debt, equity). This number is registered when the company is incorporated, subsequently, this number can be revised upward by applying to the registrar of companies. Now, this means that at max. the company is authorized to raise this much capital and no more. However, a company may raise less than this, which is called Issued Capital. In your case, the company is raising its authorized capital by applying to the registrar of companies, though in this case they are looking at their full authorized capital to be issued capital, it was not necessary to do so. Increase of Authorized capital: The main benefit is that the company can get more money in form of equity and utilize the same, perhaps, for expansion of business etc., that is the primary benefit. Bonus Share: Usually, companies keep some surplus as reserve, this money comes out of the profit the company makes and is essentially money of the shareholders. This reserve surplus is maintained for situations, when the money may be required for exigencies. However, this surplus grows over a few years and the company usually the company plans for an expansion of business. However, this money cannot be just taken, as it belongs to the shareholder, so shareholders are issued extra equity in proportion to their current holding and this surplus is capitalized i.e. used as part of the company's equity capital. Bonus declaration does not add t o the value of the company and the share prices fall in proportion (but not quite) to the bonus. "The difference is in the interrelation between the varied investments you make. Hedging is about specifically offsetting a possible loss in an investment by making another related investment that will increase in value for the same reasons that the original investment would lose value. Gold, for instance, is often regarded as the ultimate hedge. Its value is typically inversely correlated to the rest of the market as a whole, because its status as a material, durable store of value makes it a preferred ""safe haven"" to move money into in times of economic downturn, when stock prices, bond yields and similar investments are losing value. That specific behavior makes investing in gold alongside stocks and bonds a ""hedge""; the increase in value of gold as stock prices and bond yields fall limits losses in those other areas. Investment of cash in gold is also specifically a hedge against currency inflation; paper money, account balances, and even debt instruments like bonds and CDs can lose real value over time in a ""hot"" economy where there's more money than things to buy with it. By keeping a store of value in something other than currency, the price of that good will rise as the currencies used to buy it decrease in real value, maintaining your level of real wealth. Other hedges are more localized. One might, for example, trade oil futures as a hedge on a position in transportation stocks; when oil prices rise, trucking and airline companies suffer in the short term as their margins get squeezed due to fuel costs. Currency futures are another popular hedge; a company in international business will often trade options on the currencies of the companies it does business in, to limit the ""jitters"" seen in the FOREX spot market caused by speculation and other transient changes in market demand. Diversification, by contrast, is about choosing multiple unrelated investments, the idea being to limit losses due to a localized change in the market. Companies' stocks gain and lose value every day, and those companies can also go out of business without bringing the entire economy to its knees. By spreading your wealth among investments in multiple industries and companies of various sizes and global locations, you insulate yourself against the risk that any one of them will fail.  If, tomorrow, Kroger grocery stores went bankrupt and shuttered all its stores, people in the regions it serves might be inconvenienced, but the market as a whole will move on. You, however, would have lost everything if you'd bet your retirement on that one stock. Nobody does that in the real world; instead, you put some of your money in Kroger, some in Microsoft, some in Home Depot, some in ALCOA, some in PG&E, etc etc. By investing in stocks that would be more or less unaffected by a downturn in another, if Kroger went bankrupt tomorrow you would still have, say, 95% of your investment next egg still alive, well and continuing to pay you dividends. The flip side is that if tomorrow, Kroger announced an exclusive deal with the Girl Scouts to sell their cookies, making them the only place in the country you can get them, you would miss out on the full possible amount of gains you'd get from the price spike if you had bet everything on Kroger.  Hindsight's always 20/20; I could have spent some beer money to buy Bitcoins when they were changing hands for pennies apiece, and I'd be a multi-millionaire right now. You can't think that way when investing, because it's ""survivor bias""; you see the successes topping the index charts, not the failures. You could just as easily have invested in any of the hundreds of Internet startups that don't last a year." "not sure if I will help or just spread more gibberish but maybe the first concept I'd look at is risk tolerance.  Risk tolerance is discerning your ability to risk losing money to get better results.  So you know the saying ""the higher the risk the higher the reward""?  The way most people are going to operate is somewhere on the midpoint of behavior - not doing the riskiest thing, but not doing the very most cautious thing either.  So given that concept, some investments will be more appealing given different economic scenarios.  Typically stocks are going to reward your investment a little more aggressively than a treasury bond if the economy is humming along.  This drives prices of treasuries lower, stock yields higher.  In a crappy economy, people want to move their money into conservative investments like a treasury bond. Bond prices rise while stock prices dip.    If you google 'correlations between the market prices of stocks and the market prices of Treasury bonds' you will find plenty of helpful and hopefully not too convoluted articles a la http://finance.zacks.com/correlation-treasuries-stocks-10871.html Don't get freaked out by graphs, the graphs are just a way to put into a picture that correlation." A stock is an ownership interest in a company.  There can be multiple classes of shares, but to simplify, assuming only one class of shares, a company issues some number of shares, let's say 1,000,000 shares and you can buy shares of the company. If you own 1,000 shares in this example, you would own one one-thousandth of the company.  Public companies have their shares traded on the open market and the price varies as demand for the stock comes and goes relative to people willing to sell their shares. You typically buy stock in a company because you believe the company is going to prosper into the future and thus the value of its stock should rise in the open market. A bond is an indebted interest in a company.  A company issues bonds to borrow money at an interest rate specified in the bond issuance and makes periodic payments of principal and interest.  You buy bonds in a company to lend the company money at an interest rate specified in the bond because you believe the company will be able to repay the debt per the terms of the bond.  The value of a bond as traded on the open exchange varies as the prevailing interest rates vary.  If you buy a bond for $1,000 yielding 5% interest and interest rates go up to 10%, the value of your bond in the open market goes down so that the payment terms of 5% on $1,000 matches hypothetical terms of 10% on a lesser principal amount.  Whatever lesser principal amount at the new rate would lead to the same payment terms determines the new market value.   Alternatively, if interest rates go down, the current value of your bond increases on the open market to make it appear as if it is yielding a lower rate. Regardless of the market value, the company continues to pay interest on the original debt per its terms, so you can always hold onto a bond and get the original promised interest as long as the company does not go bankrupt. So in summary, bonds tend to be a safer investment that offers less potential return.  However, this is not always the case, since if interest rates skyrocket, your bond's value will plummet, although you could just hold onto them and get the low rate originally promised. "I don't have anything definitive, but in general positions in a company are not affected materially by what is called a corporate action. ""Corp Actions"" can really be anything that affects the details of a stock. Common examples are a ticker change, or exchange change, IPO (ie a new ticker), doing a split, or merging with another ticker. All of these events do not change the total value of people's positions. If a stock splits, you might have more shares, but they are worth less per share. A merger is quite similar to a split. The old company's stock is converted two the new companies stock at some ratio (ie 10 shares become 1 share) and then converted 1-to-1 to the new symbol. Shorting a stock that splits is no different. You shorted 10 shares, but after the split those are now 100 shares, when you exit the position you have to deliver back 100 ""new"" shares, though dollar-for-dollar they are the same total value. I don't see why a merger would affect your short position. The only difference is you are now shorting a different company, so when you exit the position you'll have to deliver shares of the new company back to the brokerage where you ""borrowed"" the shares you shorted." When stocks have a change in price it is because of a TRADE. To have a trade you have to have both a buyer and a seller.  When the price of a security is going up there are an equal amount of shares being sold as being bought. When the price of a security is going down there are an equal amount of shares being bought as being sold.  There almost always is an unequal amount of shares waiting to be sold compared to the amount waiting to be bought. But waiting shares do not move the price, only when the purchase price and the sale price agree, and a trade occurs, does the price move.  So the price does not go down because more shares are being sold. Neither does the price go up because more shares are being bought. I believe that capital gains do affect AGI, but if she sells $40k of stock, then the AGI doesn't go up by $40k, it only goes up by the gains (gross proceeds of the sale minus cost basis). So if she paid $30k for that stock, then the AGI goes up by $10k not $40k. The check is written to BigCo. Jack is being diluted, corporation issues more shares. There's no gain, no change in Jack's equity value. Jack didn't lose or win anything. BigCo was worth $1M before the additional money, it is worth $1.25M after the additional money, with Jack owning the same $1M, but the cake is now bigger (obviously the numbers are wrong in your example, but you get the point).
