Question on buying selling and buying again
Firstly 795 is not even. Secondly - generally you would pay tax on the sale of the 122 shares, whether you buy them back or not, even one minute later, has nothing to do with it. The only reason this would not create a capital gains event is if your country (which you haven't specified) has some odd rules or laws about this that I, and most others, have never heard of before.
"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." 1) Don't trade individual stocks. You expose yourself to unnecessary risk. 2) Pick a fund with low expenses that pays a dividend. Reinvest the dividend back into the fund.  To quote Einstein: The greatest power on earth is compound interest.  Something is wrong with the software of the site. It will not allow me to answer mark with another comment. So I have to edit this answer to be able to answer him.  @mark No, I am not hoping the price will go up. The price is only relevant in comparison to the dividend. It is the dividend that is important, not the price. The price is irrelevant if you never sell. Dividend paying securities are what you buy and hold. Then you reinvest the dividend and buy more of the security. As I am buying the security with the dividend I am actually pleasantly surprised when the price goes down. When the price goes down, but the dividend remains the same, I am able to buy more shares of the security withwith that dividend. So if the price goes down, and the dividend remains the same, it is a good thing.  Again, the site will not allow me to add another comment. @mark I profit from my investment, without selling, by receiving the dividend. I used to be a speculator, trying to get ahead of the market by 'buy low, sell high' but all that did was make money for the broker. I lost as much as I gained trying to do that. The broker made money on each transaction, regardless if I did or not. It took me decades to learn the lesson that 'buy and hold' of dividend paying securities is the way to go. Don't make my mistake. I now get, at least, 5.5% yeald on my investment (look at PGF, which forms the backbone of my investments). That is almost 0.5% per month. Each month that dividend is reinvested into PGF, with no commission. You can't beat that with a stick. "You have a good thing going. One of the luxuries of being invested in an index fund for the long term is that you don't have to sweat the inevitable short term dips in the market. Instead, look at the opportunity that presents itself on market dips: now your monthly investment is getting in at a lower price. ""Buy low, sell high."" ""Don't lose money."" These are common mantras for long term investment mentality. 5-8 years is plenty of time -- I'd call it ""medium-term"". As you get closer to your goals (~2-3 years out) you should start slowly moving money out of your index fund and start dollar cost averaging out into cash or short-term bonds (but that's another question). Keep putting money in, wait, and sell high. If it's not high, wait another year or two to buy the house. A lot of people do the opposite for their entire lives: buying high, panic selling on the dips, then buying again when it goes up. That's bad! I recommend a search on ""dollar cost averaging"", which is exactly what you are doing right now with your monthly investments." "Alrighty.  So your question is, how confident are people that FB stock will close above a certain price at a certain time.  A ""call"" option contract allows you to buy shares in the future at a certain price.  FB calls are available for March of 2013.  The number in the ""strike"" column is the price you can buy FB stock at on the given date. Let's take the ""33.00"" strike.  This allows you to buy FB shares at $33 each next March.  If at that time it turns out they're worth $50 each, you can buy them at $33, then immediately sell them on the open market for $50, making money.  The person selling you the option knows that there's a chance the price will be above $33 in March, so he's going to charge you a few bucks to cover that possibility.  In this case, he's charging you $5.30 (as of me writing this).  So, you can have the option to buy FB shares at $33 each for $5.30.  This means the guy selling you the option is reasonably confident that in March, FB stock will be at or under $38.50, otherwise he'd lose money when you exercised the option.    Therefore, $38.50 is the option market's best guess as to the highest FB stock will be going for in March." Okay...yes. However, it's the same issue. Who's going to start offering options first? Who is that person going to be? How are they going to get a hold of the stock? They're going to have to buy it first. That takes us back to the original problem. "In other words, does the market have control over sale numbers or do I? You both do, just like for the bike.  You have control over the price you ask, and the buyer has control over the price they pay.  If the two do not align, no sale takes place. Your question uses the words ""sell"" and ""sale"" ambiguously.  You can decide to ask for any price you want.  You cannot actually sell anything until someone agrees to buy what you are offering." From your question, I am guessing that you are intending to have stoploss buy order. is the stoploss order is also a buy order ?  As you also said, you seems to limit your losses, I am again guessing that you have short position of the stock, to which you are intending to place a buy limit order and buy stoploss order (stoploss helps when when the price tanks). And also I sense that you intend to place buy limit order at the price below the market price. is that the situation?  If you place two independent orders (one limit buy and one stoploss buy). Please remember that there will be situation where two orders also get executed due to market movements. Add more details to the questions. it helps to understand the situation and others can provide a strategic solution. Will there be a scenario in which I want to sell, but nobody wants to buy from me and I'm stuck at the brokerage website? Similarly, if nobody wants to sell their stocks, I will not be able to buy at all? You're thinking of this as a normal purchase, but that's not really how US stock markets operate. First, just because there are shares of stock purchased, it doesn't mean that there was real investor buyer and seller demand for that instrument (at that point in time).  Markets have dedicated middlemen called Market Makers (NASDAQ) or Specialists (NYSE), who are responsible to make sure that there is always someone to buy or sell; this ensures that all instruments have sufficient liquidity.  Market Makers and specialists may decide to lower their bid on a stock based on a high number of sellers, or raise their ask for a high number of buyers. During an investor rush to buy or sell an instrument (perhaps in response to a news release), it's possible for the Market Maker / specialist to accumulate or distribute a large number of shares, without end-investors like you or I being involved on both sides of the same transaction.
