Selling stocks as LIFO or FIFO
"According to the IRS, you must have written confirmation from your broker ""or other agent"" whenever you sell shares using a method other than FIFO: Specific share identification.   If you adequately identify the shares   you sold, you can use the adjusted basis of those particular shares to   figure your gain or loss. You will adequately identify your mutual fund shares, even if you   bought the shares in different lots at various prices and times, if   you: Specify to your broker or other agent the particular shares to be sold or transferred at the time of the sale or transfer, and Receive confirmation in writing from your broker or other agent within a reasonable time of your specification of the particular   shares sold or transferred. If you don't have a stockbroker, I'm not sure how you even got the shares. If you have an actual stock certificate, then you are selling very specific shares and the purchase date corresponds to the purchase date of those shares represented on the certificate."
Rebalance is across asset-classes which are mutually independent [like stocks and bonds; they may be inversely correlated at times as when stocks go down, bonds go up] 80%-20% (stock-bond) split is good for a young investor [say in 30s, some suggest 110-age as a good stock allocation percentage]. Here rebalance is done when say the asset-allocation(AA) strays away more than say 3 to 5% (again just a rule of thumb). E.g. if due to a recent run-up in stocks, AA could become 85%-15%. Then you sell stocks to buy bonds to make the AA 80%-20% And since this method always sells the winner -- you automatically make gains [selling high and buying low] S&P 500 index gives decent diversification within stocks; you want a total-bond-fund to take care of the bond side of your AA. "Of the two, an option is a more reliable but more expensive means to get rid of a stock. As sdg said, a put option is basically an insurance policy on the stock; you pay a certain price for the contract itself, which locks in a sale price up to a particular future date. If the stock depreciates significantly, you exercise the option and get the contract price; otherwise you let the contract expire and keep the stock. Long-term, these are bad bets as each expired contract will offset earnings, but if you foresee a near-term steep drop in the stock price but aren't quite sure, a put option is good peace of mind. A sell stop order is generally cheaper, but less reliable. You set a trigger price, say a loss of 10% of the stock's current value. If that threshold is reached, the stop order becomes a sell order and the broker will sell the stock on the market, take his commission (or a fixed price depending on your broker) and you get the rest. However, there has to be a buyer willing to buy at that price at the moment the trigger fires; if a stock has lost 10% rapidly, it's probably on the way down hard, and the order might not complete until you realize a 12% loss, or a 15%, or even 20%. A sell stop limit (a combination stop order and limit order) allows you to say that you want to sell if the stock drops to $X, but not sell if it drops below $X-Y. This allows you to limit realized losses by determining a band within which it should be sold, and not to sell above or below that price. These are cheaper because you only pay for the order if it is executed successfully; if you never need it, it's free (or very cheap; some brokers will charge a token service fee to maintain a stop or stop limit). However, if the price drops very quickly or you specify too narrow a band, the stock can drop through that band too quickly to execute the sell order and you end up with a severely depreciated stock and an unexercised order. This can happen if the company whose stock you own buys another company; VERY quickly, both stocks will adjust, the buying company will often plummet inside a few seconds after news of the merger is announced, based on the steep drop in working capital and/or the infusion of a large amount of new stock in the buying company to cover the equity of the purchased company. You end up with devalued stock and a worthless option (but one company buying another is not usually reason to sell; if the purchase is a good idea, their stock will recover). Another option which may be useful to you is a swaption; this basically amounts to buying a put option on one financial instrument and a call on another, rolled into one option contract specifying a swap. This allows you to pick something you think would rise if your stock fell and exchange your stock for it at your option. For example, say the stock on which you buy this swaption is an airline stock, and you contract the option to swap for oil. If oil surges, the airline's stock will tank sharply, and you win both ways (avoiding loss and realizing a gain). You'd also win if either half of this option realized a gain over the option price; oil could surge or the airline could tank and you could win. You could even do this ""naked"" since its your option; if the airline's stock tanks, you buy it at the crashed price to exercise the option and then do so. The downside is a higher option cost; the seller will be no fool, so if your position appears to be likely, anyone who'd bet against you by selling you this option will want a pretty high return." This is rather simple if you understand a trailing limit order but to be sure I am going to explain a limit, trailing limit, and trailing LIT order. I am going to use an example assuming that you already own a stock and want to sell it. Limit Order I place an order to sell 100 PG @ 65.00. This order will only be executed if the bid price of PG is at $65.0000 or greater. Trailing Limit Order I place an order to sell 100 CAT @ 85.25 with a trailing 5%. This order will be executed when CAT drops 5% below the highest point it reaches after you place this order. So if you place this order at 85.25 and the stock drops 5% to $80.9875, your order will be executed. However, if the stock jumps to $98, the order will not be executed until the stock falls to $93.10. The sell point will go up with the stock and will always remain at the specified % or $ amount behind the high point. Trailing Limit If Touched Order I place an order to sell 100 INTC @ 24.75 with a trailing 5% if the stock touches $25.00. Essentially, this is the same as the trailing limit except that it doesn't take effect until the stock first gets $25.00.  I think the page they provide to explain this is confusing because I think they are explaining it from the shorting a stock perspective instead of the selling a stock you want to profit from. I could also be wrong in how I understand it. My advice would be to either call their customer support and ask for a better explanation or what I do in my finances, avoid things I don't understand. "Selling short is simply by definition the selling, then later re-buying of stock you don't initially own. Say you tally your entire portfolio balance: the quantity of each stock you own, and your cash assets. Let's call this your ""initial position"". We define ""profit"" as any increase in assets, relative to this initial position. If you know a particular stock will go down, you can realize a profit by selling some of that stock, waiting for the price to go down, then buying it back. In the end you will have returned to your initial position, except you will have more cash. If you sell 10 shares of a stock valued at £1.50, then buy them back at £1.00, you will make a £5.00 profit while having otherwise returned to your previous position. If you do the same, but you initially owned 1000 shares, sold just 10 of those, then bought 10 back, that's still a profit of £5.00. Selling short is doing the same thing, but with an initial and ending balance of 0 shares. If you initially own 0 shares, sell 10, then buy 10 back, you return to your initial position (0 shares) plus a profit of £5.00. (And in practice you must also pay a borrowing fee to do this.) The advantage of selling short is it can be done with any stock, not just those currently owned." "When we say ""stock market,"" we are usually thinking of the publicly traded stocks, such as the New York Stock Exchange or the NASDAQ. Shares of individual products do not go on these exchanges, only large corporations.  You won't see a stock ticker symbol for The Force Awakens or for the iPhone 6s Plus.  The reason for this is that when investors buy a stock, they are looking for something that will grow in value theoretically forever. Individual products usually have a limited lifespan. Your movie will (hopefully) generate revenue when it comes out, but after a while sales will slow down after people have seen it. If someone bought a share of stock in a movie on the stock market, they have to realize that eventually the movie will stop making money, and their share of stock won't be worth anything anymore. Instead, people invest in companies that have the potential to make new products, such as Disney or Apple.  So if you were envisioning seeing the ticker symbol of your movie going across the screen on CNBC, sorry, that's not going to happen.  However, you could theoretically sell shares to individual investors for a percentage of the profit. You figure out how much money you need to create the movie, and estimate how much profit you think the movie will earn. Then you find an investor (or group of investors) that is willing to give you the money you need in exchange for a percentage of the profit. Unlike a stock market investor, these investors won't be looking for the long-term growth potential of the resale value of the stock, but simply a share of the profit." "(Note: out of my depth here, but in case this helps...) While not a direct answer to your question, I'll point out that in the inverse situation - a U.S. investor who wants to buy individual stocks of companies headquartered outside US - you would buy ADRs, which are $-denominated ""wrapper"" stocks.  They can be listed with one or multiple brokerages. One alternative I'd offer the person in my example would be, ""Are you really sure you want to directly buy individual stocks?""  One less targeted approach available in the US is to buy ETFs targeted for a given country (or region).   Maybe there's something similar there in Asia that would eliminate the (somewhat) higher fees associated with trading foreign stocks." In order to see whether you can buy or sell some given quantity of a stock at the current bid price, you need a counterparty (a buyer) who is willing to buy the number of stocks you are wishing to offload. To see whether such a counterparty exists, you can look at the stock's order book, or level two feed. The order book shows all the people who have placed buy or sell orders, the price they are willing to pay, and the quantity they demand at that price. Here is the order book from earlier this morning for the British pharmaceutical company, GlaxoSmithKline PLC.  Let's start by looking at the left-hand blue part of the book, beneath the yellow strip. This is called the Buy side. The book is sorted with the highest price at the top, because this is the best price that a seller can presently obtain. If several buyers bid at the same price, then the oldest entry on the book takes precedence. You can see we have five buyers each willing to pay 1543.0 p (that's 1543 British pence, or £15.43) per share. Therefore the current bid price for this instrument is 1543.0. The first buyer wants 175 shares, the next, 300, and so on. The total volume that is demanded at 1543.0p is 2435 shares. This information is summarized on the yellow strip: 5 buyers, total volume of 2435, at 1543.0. These are all buyers who want to buy right now and the exchange will make the trade happen immediately if you put in a sell order for 1543.0 p or less. If you want to sell 2435 shares or fewer, you are good to go. The important thing to note is that once you sell these bidders a total of 2435 shares, then their orders are fulfilled and they will be removed from the order book. At this point, the next bidder is promoted up the book; but his price is 1542.5, 0.5 p lower than before. Absent any further changes to the order book, the bid price will decrease to 1542.5 p. This makes sense because you are selling a lot of shares so you'd expect the market price to be depressed. This information will be disseminated to the level one feed and the level one graph of the stock price will be updated. Thus if you have more than 2435 shares to sell, you cannot expect to execute your order at the bid price in one go. Of course, the more shares you are trying to get rid of, the further down the buy side you will have to go. In reality for a highly liquid stock as this, the order book receives many amendments per second and it is unlikely that your trade would make much difference. On the right hand side of the display you can see the recent trades: these are the times the trades were done (or notified to the exchange), the price of the trade, the volume and the trade type (AT means automatic trade).  GlaxoSmithKline is a highly liquid stock with many willing buyers and sellers. But some stocks are less liquid. In order to enable traders to find a counterparty at short notice, exchanges often require less liquid stocks to have market makers. A market maker places buy and sell orders simultaneously, with a spread between the two prices so that they can profit from each transaction. For instance Diurnal Group PLC has had no trades today and no quotes. It has a more complicated order book, enabling both ordinary buyers and sellers to list if they wish, but market makers are separated out at the top. Here you can see that three market makers are providing liquidity on this stock, Peel Hunt (PEEL), Numis (NUMS) and Winterflood (WINS). They have a very unpalatable spread of over 5% between their bid and offer prices. Further in each case the sum total that they are willing to trade is 3000 shares. If you have more than three thousand Dirunal Group shares to sell, you would have to wait for the market makers to come back with a new quote after you'd sold the first 3000. "You can certainly try to do this, but it's risky and very expensive. Consider a simplified example. You buy 1000 shares of ABC at $1.00 each, with the intention of selling them all when the price reaches $1.01. Rinse and repeat, right? You might think the example above will net you a tidy $10 profit. But you have to factor in trade commissions. Most brokerages are going to charge you per trade. Fidelity for example, want $4.95 per trade; that's for both the buying and the selling. So your 1000 shares actually cost you $1004.95, and then when you sell them for $1.01 each, they take their $4.95 fee again, leaving you with a measly $1.10 in profit. Meanwhile, your entire $1000 stake was at risk of never making ANY profit - you may have been unlucky enough to buy at the stock's peak price before a slow (or even fast) decline towards eventual bankruptcy.  The other problem with this is that you need a stock that is both stable and volatile at the same time. You need the volatility to ensure the price keeps swinging between your buy and sell thresholds, over and over again. You need stability to ensure it doesn't move well away from those thresholds altogether. If it doesn't have this weird stable-volatility thing, then you are shooting yourself in the foot by not holding the stock for longer: why sell for $1.01 if it goes up to $1.10 ten minutes later? Why buy for $1.00 when it keeps dropping to $0.95 ten minutes later? Your strategy means you are always taking the smallest possible profit, for the same amount of risk. Another method might be to only trade each stock once, and hope that you never pick a loser. Perhaps look for something that has been steadily climbing in price, buy, make your tiny profit, then move on to the next company. However you still have the risk of buying something at it's peak price and being in for an awfully long wait before you can cash out (if ever). And if all that wasn't enough to put you off, brokerages have special rules for ""frequent traders"" that just make it all the more complicated. Not worth the hassle IMO."
