buying a stock while the price is going down, and buy it at a lower price
"If you bought them, you can sell them.  That does not preclude you from buying again later. You might get yourself into a situation where you need to account for a so-called ""wash sale"" on your taxes, but your broker should calculate that and report it on your 1099-B at the end of the year.  There's nothing illegal about this though - It's just a required step in the accounting of capital gains for tax purposes." 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.
"For new shares to be successfully sold, the price has to be below market price. If you currently own shares of that company, you should always get an option to buy those newly sold shares at that discounted price. The number of options depends on the relative number of shares you hold. Lets say you own 100 out of 1000 shares, currently priced at $10. 100 new shares are to be sold at $9. Since you are holding 10% of all shares, you have the option (i.e. the right) to buy 10 new (cheaper) shares (10% of 100) before anybody else can buy them. Theoretically, the money you save by getting the shares at a discounted price is equal to the money you lose by the share's value being diluted. So, if you're a shareholder and the company is increasing it's capital, you're given the right to ""go with it""." "If the stock is below its purchase price, there is no way to exit the position immediately without taking losses. Since presumably you had Good Reasons for buying that stock that haven't changed overnight, what you should probably do is just hold it and wait for the stock to come back up. Otherwise you're putting yourself into an ongoing pattern of ""buy high, sell low"", which is precisely what you don't want to do. If you actually agree with the market that you made a mistake and believe that the stock will not recover any part of the loss quickly (and indeed will continue going down), you could sell immediately and take your losses rather than waiting and possibly taking more losses. Of course if the stock DOES recover you've made the wrong bet. There are conditions under which the pros will use futures to buffer a swing. But that's essentially a side bet, and what it saves you has to be balanced against what it costs you and how certain you are that you NOW can predict the stock's motion. This whole thing is one of many reasons individuals are encouraged to work with index funds, and to buy-and-hold, rather than playing with individual stocks. It is essentially impossible to reliably ""time the market"", so all you can do is research a stock to death before making a bet on it. Much easier, and safer, to have your money riding on the market as a whole so the behavior of any one stock doesn't throw you into a panic. If you can't deal with the fact that stocks go down as well as up, you probably shouldn't be in the market." "You have heard the old adage ""Buy low, sell high"", right? That sounds so obvious that you'd have to wonder why they would ever bother coining such an expression. It should rank up there with ""Don't walk in front of a moving car"" on the Duh scale of advice. Well, your question demonstrates exactly why it isn't quite so obvious in the real world and that people need to be reminded of it.  So, in your example, the stock prices are currently low (relative to what they have been). So per that adage, do you sell or buy when prices are low? Hint: It isn't sell. Yes. Your gut is going to tell you the exact opposite thanks to the fact that our brains are unfortunately wired to make us susceptible to the loss aversion fallacy. When the market has undergone a big drop is the WORST time to stop contributing (buying stocks).  This example might help get your brain and gut to agree a little more easily: If you were talking about any other non-investment commodity, cars for instance.  Your question equates to.. I really need a car, but the prices have been dropping like crazy lately.    Maybe I should wait until the car dealers start raising their prices again before I buy one. Dollar Cost Averaging As littleadv suggested, if you have an automatic payroll deduction for your retirement account, you are getting the benefit of Dollar Cost Averaging. Because you are investing the same amount on a scheduled interval, you are buying more shares when they are cheap and fewer when they are expensive. It is like an automatic buy low strategy is built into the account. The alternative, which you are implying, is a market timing strategy. Under this strategy, instead of investing regularly you try to get in and out of investments right before they go up/drop. There are two MAJOR flaws with this approach:   1) Your brain will work against you (see above) and encourage you to do the exact opposite of what you should be doing.   2) Unless you are clairvoyant, this strategy isn't much better than gambling. If you are lucky it can work, but because of #1, the odds are stacked against you." What it means is that the stock has already moved down. Options and other derivatives follow the price of the underlying they are not a precursor to what the underlying is going to do. In other words, the price of a derivative is derived from the underlying. "In a sense, yes. There's a view in Yahoo Finance that looks like this   For this particular stock, a market order for 3000 shares (not even $4000, this is a reasonably small figure) will move the stock past $1.34, more than a 3% move.  Say, on the Ask side there are 100,000 shares, all with $10 ask. It would take a lot of orders to purchase all these shares, so for a while, the price may stay right at $10, or a bit lower if there are those willing to sell lower.  But, say that side showed $10 1000, $10.25 500, $10.50 1000. Now, the volume is so low that if I decided I wanted shares at any price, my order, a market order will actually drive the market price right up to $10.50 if I buy 2500 shares ""market"".  You see, however, even though I'm a small trader, I drove the price up. But now that the price is $10.50 when I go to sell all 2500 at $10.50, there are no bids to pay that much, so the price the next trade will occur at isn't known yet. There may be bids at $10, with asking (me) at $10.50. No trades will happen until a seller takes the $10 bid or other buyers and sellers come in." Energy Transfer Partners, LP (stock symbol ETP) is the parent company of Dakota Access LLC, the developer of the Dakota Access Pipeline.  Since ETP is a publicly traded company, it is certainly possible to purchase the stock. To answer your questions: Would it not be possible to buy their stocks, bring down the price of the stocks and keep it there until investors pull out because it is financially unwise to these investors? You cannot artificially bring the price of a stock down by buying the stock.  Purchasing large enough amounts would theoretically cause the price to go up, not down. You could theoretically cause the stock to go down by shorting the stock (borrowing shares and then selling them), but it would take a lot of shares to do this, and may not be successful.  If not successful, your losses are potentially unlimited. Would it alternatively be possible to buy enough stock to have a voice in the operations of the company? Yes, you could theoretically purchase enough of the stock to control the company.  The market capitalization of ETP is currently $17.9 Billion; if you owned half of the stock, you would have complete control of the company.  But buying that much stock would certainly influence the price of the stock, so it would cost you more than half of that amount to buy that much stock. You could get yourself a voice at the table for less without owning a full half of the stock, but you would not have full control, and would need support from others to get the outcome you want. Alternatively, someone determined to exert their influence could theoretically make an offer to purchase the Dakota Access subsidiary from ETP, which might be less costly than purchasing half of the entire corporation. Even if an extremely wealthy person were to try one of these options and destroy this company, it wouldn't necessarily stop another company from building something similar.  The investors you purchased the company from would have billions of dollars to do so with. "A simple way to ask the question might be to say ""why can't I just use the same trick with my own shares to make money on the way down? Why is borrowing someone else's shares necessary to make the concept a viable one? Why isn't it just the inverse of 'going long'?"" A simple way to think about it is this: to make money by trading something, you must buy it for less than you sell it for.  This applies to stocks like anything else.  If you believe the price will go up, then you can buy them first and sell them later for a higher price.  But if you believe the price will go down, the only way to buy low and sell high is to sell first and buy later.  If you buy the stock and it goes down, any sale you make will lose you money. I'm still not sure I fully understand the point of your example, but one thing to note is that in both cases (i.e., whether you buy the share back at the end or not), you lost money.  You say that you ""made $5 on the share price dropping"", but that isn't true at all: you can see in your example that your final account balance is negative in both cases.  You paid $20 for the shares but only got $15 back; you lost $5 (or, in the other version of your example, paid $20 and got back $5 plus the depreciated shares). If you had bought the shares for $20 and sold them for, say, $25, then your account would end up with a positive $5 balance; that is what a gain would look like.  But you can't achieve that if you buy the shares for $20 and later sell them for less. At a guess, you seem to be confusing the concept of making a profit with the concept of cutting your losses.  It is true that if you buy the shares for $20 and sell them for $15, you lose only $5, whereas if you buy them for $20 and sell for $10, you lose the larger amount of $10.  But those are both losses.  Selling ""early"" as the price goes down doesn't make you any money; it just stops you from losing more money than you would if you sold later." Yes, you can do this buy placing a conditional order to buy at market if the price moves to 106 or above. Once the price hits 106 your market order will hit the market and you will purchase the stock at 106 or above. You can also place a tack profit order at 107 linked to your initial conditional buy order, so that once you buy order is executed and you buy at 106, a take profit order will be executed only if the price reaches 107 or above.  If the price never reaches 106, neither your market buy order or take profit order will hit the market and you won't buy or sell anything. The market doesn't know or care why you bought.  What you are asking is effectively 'this share went down in price after I bought. Is there anything I can do?'. Consider what you are asking for - if there were anything you could do, then no one would ever make a loss. How do you suppose that would work? You want to buy when the stock market is at an all-time low for that day. Unfortunately, you don't know the lowest time until the end of the day, and then you, uh can't buy the stock... Now the stock market is not random, but for your case, we can say that effectively, it is. So, when should you buy the stock to hopefully get the lowest price for the day? You should wait for 37% of the day, and then buy when it is lower than it has been for all of that day. Here is a quick example (with fake data): We have 18 points, and 37% of 18 is close to 7. So we discard the first 7 points - and just remember the lowest of those 7. We bear in mind that the lowest for the first 37% was 5. Now we wait until we find a stock which is lower than 5, and we buy at that point: This system is optimal for buying the stock at the lowest price for the day. Why? We want to find the  best position to stop automatically ignoring. Why 37%? We know the answer to P(Being in position n) - it's 1/N as there are N toilets, and we can select just 1. Now, what is the chance we select them, given we're in position n? The chance of selecting any of the toilets from 0 to K is 0 - remember we're never going to buy then. So let's move on to the toilets from K+1 and onwards. If K+1 is better than all before it, we have this: But, K+1 might not be the best price from all past and future prices. Maybe K+2 is better. Let's look at K+2 For K+2 we have K/K+1, for K+3 we have K/K+2... So we have: This is a close approximation of the area under 1/x - especially as x → ∞   So 0 + 0 + ... + (K/N) x (1/K + 1/K+1 + 1/K+2 ... + 1/N-1) ≈ (K/N) x ln(N/K) and so P(K) ≈ (K/N) x ln(N/K) Now to simplify, say that x = K/N We can graph this, and find the maximum point so we know the maximum P(K) - or we can use calculus. Here's the graph:  Here's the calculus: To apply this back to your situation with the stocks, if your stock updates every 30 seconds, and is open between 09:30 and 16:00, we have 6.5 hours = 390 minutes = 780 refreshes. You should keep track of the lowest price for the first 289 refreshes, and then buy your stock on the next best price. Because x = K/N, the chance of you choosing the best price is 37%. However, the chance of you choosing better than the average stock is above 50% for the day. Remember, this method just tries to mean you don't loose money within the day - if you want to try to minimise losses within the whole trading period, you should scale this up, so you wait 37% of the trading period (e.g. 37% of 3 months) and then select. The maths is taken from Numberphile - Mathematical Way to Choose a Toilet. Finally, one way to lose money a little slower and do some good is with Kiva.org - giving loans to people is developing countries. It's like a bank account with a -1% interest - which is only 1% lower than a lot of banks, and you do some good. I have no affiliation with them. If you believe the stock market will be down 20-30% in the next few months, sell your stock holdings, buy a protective put option for the value of the holdings that you want to keep. That would be hedging against it. Anything more is speculating that the market will fall. "It works if after the price has halved and you buy more the price then rises, however if you are attempting to do this you are basing you ""doubling down"" on hope, and if you are basing a purchase on hope you are gambling. In many cases if the price has halved it could be because there is something very wrong with the company, so the price could easly half again. In that case it hasn't worked. You are better off waiting to see if the company makes a turn around and starts improving. Wait for confirmation that the stock price is heading back up before buying." "The process of borrowing shares and selling them is called shorting a stock, or ""going short.""  When you use money to buy shares, it is called ""going long."" In general, your strategy of going long and short in the same stock in the same amounts does not gain you anything.  Let's look at your two scenarios to see why. When you start, LOOT is trading at $20 per share.  You purchased 100 shares for $2000, and you borrowed and sold 100 shares for $2000.  You are both long and short in the stock for $2000.  At this point, you have invested $2000, and you got your $2000 back from the short proceeds.  You own and owe 100 shares. Under scenario A, the price goes up to $30 per share.  Your long shares have gone up in value by $1000.  However, you have lost $1000 on your short shares.  Your short is called, and you return your 100 shares, and have to pay interest.  Under this scenario, after it is all done, you have lost whatever the interest charges are. Under scenario B, the prices goes down to $10 per share.  Your long shares have lost $1000 in value.  However, your short has gained $1000 in value, because you can buy the 100 shares for only $1000 and return them, and you are left with the $1000 out of the $2000 you got when you first sold the shorted shares.  However, because your long shares have lost $1000, you still haven't gained anything.  Here again, you have lost whatever the interest charges are. As explained in the Traders Exclusive article that @RonJohn posted in the comments, there are investors that go long and short on the same stock at the same time.  However, this might be done if the investor believes that the stock will go down in a short-term time frame, but up in the long-term time frame.  The investor might buy and hold for the long term, but go short for a brief time while holding the long position. However, that is not what you are suggesting.  Your proposal makes no prediction on what the stock might do in different periods of time.  You are only attempting to hedge your bets.  And it doesn't work.  A long position and a short position are opposites to each other, and no matter which way the stock moves, you'll lose the same amount with one position that you have gained in the other position.  And you'll be out the interest charges from the borrowed shares every time. With your comment, you have stated that your scenario is that you believe that the stock will go up long term, but you also believe that the stock is at a short-term peak and will drop in the near future.  This, however, doesn't really change things much.  Let's look again at your possible scenarios. You believe that the stock is a long-term buy, but for some reason you are guessing that the stock will drop in the short-term.  Under scenario A, you were incorrect about your short-term guess.  And, although you might have been correct about the long-term prospects, you have missed this gain.  You are out the interest charges, and if you still think the stock is headed up over the long term, you'll need to buy back in at a higher price. Under scenario B, it turns out that you were correct about the short-term drop.  You pocket some cash, but there is no guarantee that the stock will rise anytime soon.  Your investment has lost value, and the gain that you made with your short is still tied up in stocks that are currently down. Your strategy does prevent the possibility of the unlimited loss inherent in the short.  However, it also prevents the possibility of the unlimited gain inherent in the long position.    And this is a shame, since you fundamentally believe that the stock is undervalued and is headed up.  You are sabotaging your long-term gains for a chance at a small short-term gain." If you are looking for a simple formula or buying order / strategy to guarantee a lower buying price, unfortunately this does not exist.  Otherwise, all investors would employ this strategy and the financial markets would no longer have an validity (aka arbitrage).  Buying any investment contains a certain level of risk (other than US treasuries of course). Having said that, there are many option buying strategies that can employed to help increase your ROR or hedge an existing position.  Most of these strategies are based a predicted future direction of a stock on the investor's part.  For example, you hold the Ford stock and feel they are releasing their earnings report next week.  You feel that they will not meet investors' expectations.  You don't want to sell your shares but what you can do is buy put options.  If the stock does indeed go down then you make money on your put options. Here is a document on options.  It is moderately technical but very good if you want a good introduction on the subject.  The strategy that I described above is on pg 33. http://www.m-x.ca/f_publications_en/en.guide.options.pdf It might go down a bit, or it might not. That is nearly impossible to predict, as the relative volumes are unknown, and the exact procedure is also unknown (they might do the selling over a longer period, or as a buy back, or immediately, or...) However, why would you want to wait at all? It is generally not a great idea to put your savings into the company you work for ('all eggs in one basket' - when it goes down, you lose your job and your savings), so the best approach is to pick a good day in the next weeks and sell the stock and invest into something more neutral.
