Why would people sell a stock below the current price?
"Say we have stock XYZ that costs $50 this second. It doesn't cost XYZ this second. The market price only reflects the last price at which the security traded. It doesn't mean that if you'll get that price when you place an order. The price you get if/when your order is filled is determined by the bid/ask spreads. Why would people sell below the current price, and not within the range of the bid/ask? Someone may be willing to sell at an ask price of $47 simply because that's the best price they think they can sell the security for. Keep in mind that the ""someone"" may be a computer that determined that $47 is a reasonable ask price. Remember that bid/ask spreads aren't fixed, and there can be multiple bid/ask prices in a market at any given time. Your buy order was filled because at the time, someone else in the market was willing to sell you the security for the same price as your bid price. Your respective buy/sell orders were matched based on their price (and volume, conditional orders, etc). These questions may be helpful to you as well: Can someone explain a stock's ""bid"" vs. ""ask"" price relative to ""current"" price? Bids and asks in case of market order Can a trade happen ""in between"" the bid and ask price? Also, you say you're a day trader. If that's so, I strongly recommend getting a better grasp on the basics of market mechanics before committing any more capital. Trading without understanding how markets work at the most fundamental levels is a recipe for disaster." "Firstly, if a stock costs $50 this second, the bid/ask would have to be 49/50.  If the bid/ask were 49/51, the stock would cost $51 this second.  What you're likely referring to is the last trade, not the cost.  The last trading price is history and doesn't apply to future transactions. To make it simple, let's define a simple order book.  Say there is a bid to buy 100 at $49, 200 at $48, 500 at $47.  If you place a market order to sell 100 shares, it should all get filled at $49.  If you had placed a market order to sell 200 shares instead, half should get filled at $49 and half at $48.  This is, of course, assuming no one else places an order before you get yours submitted.  If someone beats you to the 100 share lot, then your order could get filled at lower than what you thought you'd get.  If your internet connection is slow or there is a lot of latency in the data from the exchange, then things like this could happen.  Also, there are many ECNs in addition to the exchanges which may have different order books.  There are also trades which, for some reason, get delayed and show up later in the ""time and sales"" window. But to answer the question of why someone would want to sell low... the only reason I could think is they desire to drive the price down." "Why would people sell below the current price, and not within the range of the bid/ask? There are many scenarios where this is deliberate but all of them boil down to the fact that the top level's bid doesn't support the quantity you're trying to sell (or is otherwise bogus[1]). One scenario as an example: You're day-trading both sides but at the end of the day you accumulated a rather substantial long position in a stock.  You don't want to (or aren't allowed to[2]) be exposed overnight, however.  What do you do? You place an order that is highly likely to go through altogether.  There's several ways to achieve that but a very simple one is to look at the minimum bid level for which the bid side is willing to take all of your shares, then place a limit order for the total quantity at that price.  If your position doesn't fit into the top level bid that price will well be lower than the ""current"" bid. Footnotes: [1] Keyword: quote stuffing [2] Keyword: overnight margin (aka positional margin, as opposed to intraday margin), this is highly broker dependent, exchanges don't usually distinguish between intraday and overnight margins, instead they use the collective term maintenance margin" The person may just want to get out of that position in order to buy a different stock, he or she feels may go up faster. There is really a lot of reasons. "People in this case, are large institutional investors. The ""bid ask"" spread is for ""small traders"" like yourself. It is put out by the so-called specialists (or ""market makers"") and is typically good for hundreds or thousands of shares at a time. Normally, 2 points on a 50 stock is a wide spread, and the market maker will make quite a bit of money on it trading with people like yourself. It's different if a large institution, say Fidelity, wants to sell, say 1 million shares of the stock. Depending on market conditions, it may have trouble finding buyers willing to buy in those amounts anywhere near 50. To ""move"" such a large block of stock, they may have to put the equivalent of K-Mart's old ""Blue Light Special"" on, several points below." This happens on dark pools quite often. If I am a large institutional investor with tens of millions of shares, I may want to unload slowly and limit the adverse affects on the price of the stock. Dark pools offer anonymity and have buyers / sellers that can handle large volume.  In the case of a day trader, they often trade stocks with light volume (since they have large fluctuations that can be quite profitable throughout the session). At the end of the session, many traders are unwilling to hold positions on margin and want to unload fast. "Occassionaly a trader will make a blatant mistake. A customer calls to buy 100 shares at $10, and the trader by mistake enters ""10 shares at $100"". You get one very happy seller :-) In the USA, it doesn't happen often for sales, because if the trader offers to sell 10 shares at $100, there will be nobody accepting the other.  In Japan, with one dollar equal to 120 Yen, the same mistake would mean that someone wanted to sell 100 shares at 1200 Yen, and the trader enters 1200 shares for 100 Yen, then you will get a happy buyer, and a massive loss." 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.
"Yes there is, it is called a One-Cancels-the-Other Order (OCO). Investopedia defines a OCO order as: Definition of 'One-Cancels-the-Other Order - OCO' A pair of orders stipulating that if one order is executed, then the   other order is automatically canceled. A one-cancels-the-other order   (OCO) combines a stop order with a limit order on an automated trading   platform. When either the stop or limit level is reached and the order   executed, the other order will be automatically canceled. Seasoned   traders use OCO orders to mitigate risk. I use CMC Markets in Australia, and they allow free conditional and OCO orders either when initially placing a buy order or after already buying a stock. See the Place New Order box below:  Once you have selected a stock to buy, the number of shares you want to buy and at what price you can place up to 3 conditional orders. The first condition is a ""Place order if..."" conditional order. Here you can place a condition that your buy order will only be placed onto the market if that condition is met first.  Say the stock last traded at $9.80 and you only want to place your order the next day if the stock price moves above the current resistance at $10.00. So you would Place order if Price is at or above $10.00. So if the next day the price moves up to $10 or above your order will be placed onto the market. The next two conditional orders form part of the OCO Orders. The second condition is a ""Stop loss"" conditional order. Here you place the price you want to sell at if the price drops to or past your stop loss price. It will only be placed on to the market if your buy order gets traded. So if you wanted to place your stop loss at $9.00, you would type in 9.00 in the box after ""If at or below ?"" and select if you want a limit or market order. The third condition is a ""Take profit"" conditional order. This allows you to take profits if the stock reaches a certain price. Say you wanted to take profits at 30%, that is if the price reached $13.00. So you would type in 13.00 in the box after ""If at or above ?"" and again select if you want a limit or market order. Once you have bought the stock if the stop order gets triggered then the take profit order gets cancelled automatically. If on the other hand the take profit order gets triggered then the stop loss order gets cancelled automatically. These OCO conditional orders can be placed either at the time you enter your buy order or after you have already bought the stock, and they can be edited or deleted at any time. The broker you use may have a different process for entering conditional and OCO orders such as these." I can think of a few simple and quick techniques for timing the market over the long term, and they can be used individually or in combination with each other. There are also some additional techniques to give early warning of possible turns in the market. The first is using a Moving Average (MA) as an indication of when to sell. Simply if the price closes below the MA it is time to sell. Obviously if the period you are looking at is long term you would probably use a weekly or even monthly chart and use a relatively large period MA such as a 50 week or 100 week moving average. The longer the period the more the MA will lag behind the price but the less false signals and whipsawing there will be. As we are looking long term (5 years +) I would use a weekly chart with a 100 week Exponential MA. The second technique is using a Rate Of Change (ROC) Indicator, which is a momentum indicator. The idea for timing the markets in the long term is to buy when the indicator crosses above the zero line and sell when it crosses below the zero line. For long term investing I would use a 13 week EMA of the 52 week ROC (the EMA smooths out the ROC indicator to reduce the chance of false signals). The beauty of these two indicators is they can be used effectively together. Below are examples of using these two indicators in combination on the S&P500 and the Australian S&P ASX200 over the past 20 years.  S&P500 1995 to 2015  ASX200 1995 to 2015 If I was investing in an ETF tracking one of these indexes I would use these two indicators together by using the MA as an early warning system and maybe tighten any stop losses I have so that if the market takes a sudden turn downward the majority of my profits would be protected. I would then use the ROC Indicator to sell out completely out of the ETF when it crosses below zero or to buy back in when the ROC moves back above zero. As you can see in both charts the two indicators would have kept you out of the market during the worst of the downfalls in 2000 and 2008 for the S&P500 and 2008 for the ASX200. If there is a false signal that gets you out of the market you can quite easily get back in if the indicator goes back above zero. Using these indicators you would have gotten into the market 3 times and out of it twice for the S&P500 over a 20 year period. For the ASX200 you would have gone in 6 times and out 5 times, also over a 20 year period. For individual shares I would use the ROC indicator over the main index the shares belong to, to give an indication of when to be buying individual stocks and when to tighten stop losses and stay on the sidelines. My philosophy is to buy rising stocks in a rising market and sell falling stocks in a falling market. So if the ROC indicator is above zero I would be looking to buy fundamentally healthy stocks that are up-trending and place a 20% trailing stop loss on them. If I get stopped out of one stock then I would look to replace it with another as long as the ROC is still above zero. If the ROC indicator crosses below zero I would tighten my trailing stop losses to 5% and not buy any new stocks once I get stopped out. Some additional indicators I would use for individual stock would be trend lines and using the MACD as a momentum indicator. These two indicators can give you further early warning that the stock may be about to reverse from its current trend, so you can tighten your stop loss even if the ROC is still above zero. Here is an example chart to explain:  GEM.AX 3 Year Weekly Chart Basically if the price closes below the trend line it may be time to close out the position or at the very least tighten up your trailing stop loss to 5%. If the price breaks below an established uptrend line it may well be the end of the uptrend. The definition of an uptrend is higher highs and higher lows. As GEM has broken below the uptrend line and has maid a lower low, all that is needed to confirm the uptrend is over is a lower high. But months before the price broke below the uptrend line, the MACD momentum indicator was showing bearish divergence between it and the price. In early September 2014 the price made a higher high but the MACD made a lower high. This is called a bearish divergence and is an early warning signal that the momentum in the uptrend is weakening and the trend could be reversing soon. Notice I said could and not would. In this situation I would reduce my trailing stop to 10% and keep a watchful eye on this stock over the coming months. There are many other indicators that could be used as signals or as early warnings, but I thought I would talk about some of my favourites and ones I use on a daily and weekly basis. If you were to employ any of these techniques into your investing or trading it may take a little while to learn about them properly and to implement them into your trading plan, but once you have done that you would only need to spend 1 to 2 hours per week managing your portfolio if trading long-term or about 1 hour per nigh (after market close) if trading more medium term. "There are several reasons. First, if you sell your stock ""at any price"", you may be selling it for less than you originally bought it for.  Thus you will take a loss right at the beginning of your scheme.  If you ""rinse and repeat"", the problem only gets worse.  Every time you sell your stock, you will have to sell it at an even lower price in order to lower the price even more.  Then you buy it back and. . . just resell it an even lower price?  It should be clear that you are not making any money this way. Second, even if you don't sell it at an absolute loss, you must sell it at a relative loss in order to lower the price.  In other words, if someone will currently buy your shares for $X, and you want to lower the price, you must sell them for less than $X.  But you could have made more money by selling them for $X, since someone was already willing to buy them at that price.  In order to bring the price down significantly, you have to sell the stock for less than people currently believe it is worth, which means you're incurring a loss relative to just selling it at the market rate.  Of course, you can still make money if it goes back up again, but selling it at an extra loss this way just makes it harder to break even. Third, if you sell the stock at $X, whoever you sold it to is not going to sell it right back to you at $X, because then they would not make any money.  You could in theory buy it from someone else, but the same principle holds: if the stock price has just gone down, people who have it may be waiting for it to go back up.  This is doubly true if anyone suspects you have been trying to manipulate the stock price, because they will then suspect that the price drop is artificial and it will soon go back up. Fourth, even if someone did sell it right back to you at the price you sold it for, then what?  You now hold the stock at a lower price, but you don't gain unless it goes back up.  If it wasn't going up before until you took action, there is no reason to suppose it will go back up now.  In fact, if you had enough shares to significantly influence the price, other people may have been fooled into thinking the value is actually lower now. The basic problem is that, in order for you to buy it at a low price, someone else has to sell it at that low price.  It is easy to sell someone a stock for less than it's worth, but it will be hard to get people to sell it back to you for less than it's worth.  If you engage in deceptive practices to get people to do this, you may be guilty of securities fraud." "The correct answer to this question is:  the person who the short sells the stock to. Here's why this is the case.  Say we have A, who owns the stock and lends it to B, who then sells it short to C. After this the price drops and B buys the stock back from D and returns it to A. The outcome for A is neutral.  Typically stock that is sold short must be held in a margin account; the broker can borrow the shares from A, collect interest from B, and A has no idea this is going on, because the shares are held in a street name (the brokerage's name) and not A. If A decides during this period to sell, the transaction will occur immediately, and the brokerage must shuffle things around so the shares can be delivered.  If this is going to be difficult then the cost for borrowing shares becomes very high. The outcome for B is obviously a profit: they sold high first and bought (back) low afterwards. This leaves either C or D as having lost this money.  Why isn't it D? One way of looking at this is that the profit to B comes from the difference in the price from selling to C and buying from D.  D is sitting on the low end, and thus is not paying out the profit.  D bought low, compared to C and this did not lose any money, so C is the only remaining choice. Another way of looking at it is that C actually ""lost"" all the money when purchasing the stock.  After all, all the money went directly from C to B.  In return, C got some stock with the hope that in the future C could sell it for more than was paid for it.  But C literally gave the money to B, so how could anybody else ""pay"" the loss? Another way of looking at it is that C buys a stock which then decreases in value.  C is thus now sitting on a loss.  The fact that it is currently only a paper loss makes this less obvious; if the stock were to recover to the price C bought at, one might conclude that C did not lose the money to B.  However, in this same scenario, D also makes money that C could have made had C bought at D's price, proving that C really did lose the money to B. The final way of seeing that the answer is C is to consider what happens when somebody sells a stock which they already hold but the price goes up; who did they lose out on the gain to?  The person again is; who bought their stock.  The person would buys the stock is always the person who the gain goes to when the price appreciates, or the loss comes out of if the price falls." buy above the current price in the stock market You can do that, but what is the purpose to do so ? Brokers take the limit price of your order as the highest price you are going to pay. So if an order can be fulfilled below the limit they will do so.  can I sell below the current price  You can put in a order to do so. But what I have seen with my current broker is that the order never reached the market and wasn't executed at all. The broker might have some safeguards or process in place to stop me from doing so. Not sure how other brokers deal with it. You talk about an individual not being advised to sell (or purchase) in response to trends in the market in such a buy and hold strategy. But think of this for a moment: You buy stock ABC for $10 when both the market as a whole and stock ABC are near the bottom of a bear market as say part of a value buying strategy. You've now held stock ABC for a number of years and it is performing well hitting $50. There is all good news about stock ABC, profit increases year after year in double digits. Would you consider selling this stock just because it has increased 400%. It could start falling in a general market crash or it could keep going up to $100 or more. Maybe a better strategy to sell ABC would be to place a trailing stop of say 20% on the highest price reached by the stock. So if ABC falls, say in a general market correction, by less than 20% off its high and then rebounds and goes higher - you keep it. If ABC however falls by more than 20% off its high you automatically sell it with your stop loss order. You may give 20% back to the market if the market or the stock crashes, but if the stock continues going up you benefit from more upside in the price. Take AAPL as an example, if you bought AAPL in March 2009, after the GFC, for about $100, would you have sold it in December 2011 when it hit $400. If you did you would have left money on the table. If instead you placed a trailing stop loss on AAPL of 20% you would have been still in it when it hit its high of $702 in September 2012. You would have finally been stopped out in November 2012 for around the $560 mark, and made an extra $160 per share. And if your thinking, how about if I decided to sell AAPL at $700, well I don't think many would have picked $700 as the high in hindsight. The main benefit of using stop losses is that it takes your emotions out of your trading, especially your exits. Their reasoning is probably that by eliminating the option for company stock, employees now are exposed to less risk. That is, if the company goes bk, they're only exposed to the company through their paycheck and not their paycheck plus retirement savings.   In reality, it's probably a classic case of buy high and sell low. That is, your plan admin (HR or legal, probably) thinks that since the price went down, they should sell. The reason a company creates more stock is to generate more capital so that this can be utilized and more returns can be generated. It is commonly done as a follow on public offer. Typically the funds are used to retire high cost debts and fund future expansion. What stops the company from doing it?   Are Small investors cheated?   It's like you have joined a car pool with 4 people and you are beliving that you own 1/4th of the total seats ... so when most of them decide that we would be better of using Minivan with 4 more persons, you cannot complain that you now only own 1/8 of the total seats. Even before you were having just one seat, and even after you just have one seat ... overall it maybe better as the ride would be good ... :)
