Is it possible to lower the price of a stock while buying?
"You can choose to place successively lower buy limit orders, but whether they get filled or not is not a given; it depends on whether sellers care to accept your bid. In your example of a 49.98 / 50.01 spread, if you place a buy with limit of 49.99, it won't get filled (if the order reaches the market while still at 49.98 / 50.01) immediately, but will be added to the order book.  By being added to the order book, the markets bid and ask become 49.99 / 50.01.  Your order won't get filled until some seller places a market order or a sell limit order of 49.99 or less.  No guarantee that that will happen, and even if it does, there's nothing to say that your follow-up buy at 49.98 will ever be filled.  In fact, your 49.98 buy order queues up at the ""end of the line"" behind all previously pending 49.98 bids, since your order arrived after those other bids.  Since the initial conditions you supposed had a 49.98 bid, such an order exists (or at least did exist; it might have been cancelled in the intervening moment. Basically, your first buy at 49.99, if it happens, has essentially no influence on whether your second buy at 49.98 will happen.  You can't expect to move the market lower by making a bid that is higher (49.99) than the existing best bid (49.98).  Whatever influence your 49.99 order has is to raise the market's price, not lower it." The strategy could conceivably work if you had sufficient quantity of shares to fill all of the outstanding buy orders and fill your lower buy orders.  But in this case you are forcing the market down by selling and reinforcing the notion that there is a sell off by filling ever lower buy orders.  There is the potential to trigger some stop loss orders if you can pressure it low enough.  There is a lot of risk here that someone sees what you are doing and decides to jump in and buy forcing the price back up.  Could this work sure.  But it is very risky and if you fail to create the panic selling then you risk losing big.  I also suspect that this would violate SEC Rules and several laws.  And if the price drops too far then trading on the stock would be halted and is likely to return at the appropriate price. Bottom line I can not see a scenario where you do not trigger the stop, net a profit and end up with as many or more stock that you had in the first place.
In the US, it is perfectly legal to execute what you've described. However, since you seem to be bullish on the stock, why sell? How do you KNOW the price will continue downwards? Aside from the philosophical reasoning, there can be significant downside to selling shares when you're expecting to repurchase them in the near future, i.e. you will lose your cost basis date which determines whether or not your trade is short-term (less than 1 year) or long-term. This cost basis term will begin anew once you repurchase the shares. IF you are trying to tax harvest and match against some short-term gains, tax loss harvesting prior to long-term treatment may be suitable. Otherwise, reexamine your reasoning and reconsider the sale at all, since you are bullish. Remember: if you could pick where stock prices are headed in the short term with any degree of certainty you are literally one of a kind on this planet ;-).  In addition, do remember that in a tax deferred account (e.g. IRA) the term of your trade is typically meaningless but your philosophical reasoning for selling should still be examined. "Yes it is possible, as long as the broker you use allows conditional orders. I use CMC Markets in Australia, and they allow free conditional 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 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 50%, that is if the price reached $15.00. So you would type in 15.00 in the box after ""If at or above ?"" and again select if you want a limit or market order. These conditional orders can all be placed at the time you enter your buy order and can be edited or deleted at any time. The broker you use may have a different process for entering conditional orders, and some brokers may have many more conditional orders than these three, so investigate what is out there and if you are confused in how to use the orders with your broker, simply ask them for a demonstration in how to use them." You can execute block trades on the options market and get exercised for shares to create a very large position in Energy Transfer Partners LP without moving the stock market. You can then place limit sell orders, after selling directly into the market and keep an overhang of low priced shares (the technical analysis traders won't know what you specifically are doing, and will call this 'resistance'). If you hit nice even numbers (multiples of 5, multiples of 10) with your sell orders, you can exacerbate selling as many market participants will have their own stop loss orders at those numbers, causing other people to sell at lower and lower prices automatically, and simultaneously keep your massive ask in effect. If your position is bigger than the demand then you can keep a stock lower. The secondary market doesn't inherently affect a company in any way. But many companies have borrowed against the price of their shares, and if you get the share price low enough they can get suddenly margin called and be unable to service their existing debt. You will also lose a lot of money doing this, so you can also buy puts along the way or attempt to execute a collar to lower your own losses. The collar strategy is nice because it is unlikely that other traders and analysts will notice what you are doing, since there are calls, puts and share orders involved in creating it. One person may notice the block trade for the calls initially, but nobody will notice it is part of a larger strategy with multiple legs. With the share position, you may also be able to vote on some things, but that solely depends on the conditions of the shares. "If the price used to be 2.50 but by the time you get in an order it's 2.80, you're going to have to pay 2.80. You can't say, ""I want to buy it at the price from an hour ago"". If you could, everybody would wait for the price to go up, then buy at the old price and have an instant guaranteed profit. Well, except that when you tried to sell, I suppose the buyer could say, ""I want to pay the lower price from last July"". So no, you always buy or sell at the current price. If you submit an order after the markets close, your broker should buy the stock for you as soon as possible the next morning. There's no strict queue. There are thousands of brokers out there, they don't take turns. So if your broker has 1000 orders and you are number 1000 on his list, while some other broker has 2 orders and number 1 is someone else wanting to buy the same stock, then even if you got your order in first, the other guy will probably get the first buy. LIFO and FIFO refer to any sort of list or queue, but don't really make sense here. When the market opens a broker has a list of orders he received overnight, which he might think of as a queue. He presumably works his way down the list. But whether he follows a strict and simple first-in-first-out, or does biggest orders first, or does buys for stocks he expects to go up today and sells for stocks he expects to go down today first, or what, I don't know. Does anybody on this forum know, are there rules that say brokers have to go through the overnight orders FIFO, or what is the common practice?" Ignoring brokerage fees and the wash-sale rule (both of which are hazardous to your health), and since the 15% LTCG tax is only on the gain, the stock would have to drop 15% of the gain in price since you originally purchased it. No, this isn't possible, especially not when you're trading a highly liquid stock like Apple. When you put in your buy order at $210, any other traders that have open limit sell orders with the correct parameters, e.g. price and volume, will have their order(s) filled. This will occur before you can put in your own sell order and purchase your own shares because the other orders are listed on the order book first. In the US, many tax-sheltered accounts like IRA's have specific rules against self-dealing, which includes buying and selling assets with yourself, so such a transaction would be prohibited by definition. Although I'm not entirely sure if this applies to stocks, the limitation described in the first paragraph still applies regardless. If this were possible, rest assured that high-frequency traders would take advantage of this tactic to manipulate share prices. (I've heard critics say that this does occur, but I haven't researched it myself or seen any data about it) In order: A seller of the stock (duh!). You don't know who or why this stock was sold. It could be any reason, and is of no concern of yours. It doesn't matter. Investors (pension funds, hedge funds, individual investors, employees, management) sell stock for many reasons: need cash, litigation, differing objectives, sector rotation, etc. To you, this does not matter. Yes, it does affect stock market prices: If you were not willing to buy that amount of shares, and there were no other buyers at that price, the seller would likely choose to lower the price offered. By your purchase, you are supporting the price. The 'normal' series of events when trading a stock is to buy it, time passes, then you sell it. If you believe the stock will drop in price, you can reverse the order, selling shares, waiting for the price drop, then buying them back. During that time you own say, -100 shares, and are 'short' those shares. "If you're asking this question, you probably aren't ready to be buying individual stock shares, and may not be ready to be investing in the market at all.  Short-term in the stock market is GAMBLING, pure and simple, and gambling against professionals at that. You can reduce your risk if you spend the amount of time and effort the pros do on it, but if you aren't ready to accept losses you shouldn't be playing and if you aren't willing to bet it all on a single throw of the dice you should diversify and accept lower potential gain in exchange for lower risk. (Standard advice: Index funds.)  The way an investor, as opposed to a gambler, deals with a stock price dropping -- or surging upward, or not doing anything! -- is to say ""That's interesting. Given where it is NOW, do I expect it to go up or down from here, and do I think I have someplace to put the money that will do better?"" If you believe the stock will gain value from here, holding it may make more sense than taking your losses.  Specific example: the mortgage-crisis market crash of a few years ago. People who sold because stock prices were dropping and they were scared -- or whose finances forced them to sell during the down period -- were hurt badly. Those of us who were invested for the long term and could afford to leave the money in the market -- or who were brave/contrarian enough to see it as an opportunity to buy at a better price -- came out relatively unscathed; all I have ""lost"" was two years of growth. So: You made your bet. Now you have to decide: Do you really want to ""buy high, sell low"" and take the loss as a learning experience, or do you want to wait and see whether you can sell not-so-low. If you don't know enough about the company to make a fairly rational decision on that front, you probably shouldn't have bought its stock." It depends completely on the current order book for that security.  There is literally no telling how that buy order would move the price of a stock in general. There are 2 approaches. One of them is already mentioned by @Afforess. If the approach by @Afforess is not feasible, and you can not see yourself making an unbiased decision, close the position.  By closing the position you will not get the best price. But by removing a distraction you will reduce amount of mistakes you make in the other stocks. How would this trade behave IRL? I don't know how the simulation handles limit orders and bid/ask spreads to know it's feasible, but buying at 4.04 when the current ask is 8.00 seems unlikely.  That would mean that all other sell orders between 8.00 and 4.04 were fulfilled, which means that there were very few sellers or that sell pressure spiked, both of which seem unlikely. In reality, it seems more likely that your order would have sat there until the ask dropped to $4.04 (if it ever did), and then you'd have to wait until the bid rose to $7.89 in order to sell them at that price. However, that kind of swing in option prices in not unrealistic.  Options near at-the-money tend to move in price at about 50% of the change in the underlying, so if amazon suddenly dropped by $5, the option price could drop by $2.60 (from 6.66 to $4.04), and then rise back to $7.89 if the price rose $8 (which would be 1% swing and not unheard of intra-day). But it sounds like you got very lucky (or the simulation doesn't handle option trading realistically) - I've traded options in the past and have had some breaks similar to yours.  I've also had bad breaks where I lost my entire investment (the options expire out-of-the money). So it should be a very limited part of your portfolio, and probably only used for risk management (e.g. buying put options to lock in some gains but keeping some upside potential). "Stock prices are set by bidding. In principle, a seller will say, ""I want $80."" If he can't find anyone willing to buy at that price, he'll either decide not to sell after all, or he'll lower his price. Likewise, a buyer will say, ""I'll pay $70."" If he can't find anyone willing to pay that price, he'll either decide not to buy or he'll increase his price. For most stocks there are many buyers and many sellers all the time, so there's a constant interplay. The typical small investor has VERY little control of the price. You say, ""I want to buy 10 shares of XYZ Corporation and my maximum price is $20."" If the current trending price is below $20, your broker will buy it for you. If not, he won't. You normally have some time limit on the order, so if the price falls within your range within that time period, your broker will buy. That is, your choice is basically to buy or not buy, or sell or not sell, at the current price. You have little opportunity to really negotiate a better price. If you have a significant percentage of a company's total stock, different story. In real life, most stocks are being traded constantly, so buyers and sellers both have a pretty good idea of the current price. If the last sale was ten minutes ago for $20, it's unlikely anyone's going to now bid $100. They're going to bid $20.50 or $19.25 or some such. If the last sale was for $20 and your broker really came to the floor and offered to buy for $100, I suppose someone would sell to him very quickly before he realized what an outrageous price this was. I use TD Ameritrade, and on their web site, if I give a price limit on a buy that's more than a small percentage above the last sale, they reject it as an error. I forget the exact number but they won't even accept a bid of $80 if the stock is going for $40. They might accept $41 or $42, something like that." "In a way yes but I doubt you'd want that. A ""Stop-Limit"" order has both stop and limit components to it but I doubt this gives you what you want. In your example, if the stock falls to $1/share then the limit order of $3/share would be triggered but this isn't quite what I'd think you'd want to see. I'd suggest considering having 2 orders: A stop order to limit losses and a limit order to sell that are separate rather than fusing them together that likely isn't going to work." A stop-loss does not guarantee a sale at the given price; it just automatically triggers an unlimited sale as soon as the market reaches the limit. Depending on the development, your sale could be right at, slightly under, or deeply under the stop-loss limit you gave - it could even be it is never executed, if there are no further deals. The point is that each sell needs a partner that buys for that price, and if nobody is buying, no sale happens, no matter what you do (automated or manually) - your stop loss cannot 'force' a sale. Stop-loss works well for minor corrections in liquid shares; it becomes less useful the less liquid a share is, and it will not be helpfull for seldomly traded shares.
