What prevents investors from buying high yield stocks and selling them as soon as their dividend is paid out?
"You have to be the owner of record before the ex-dividend date, which is not the same day as the date the dividend is paid. This also implies that if you sell on or after the ex-dividend date, you'll still get the dividend, even if you no longer own the stock.  Keep in mind, also, that the quoted price of the stock (and on any open orders that are not specifically marked as ""do not reduce"") on its ex-dividend date is dropped by the amount of the dividend, first thing in the morning before trading starts. If you happen to be the first order of the day, before market forces cause the price to move, you'll end up with zero gain, since the dividend is built into the price, and you got the same value out of it -- the dividend in cash, and the remaining value in stock. As pointed out in the comments (Thanks @Brick), you'll still get a market price for your trade, but the price reduction will have had some impact on the first trade of the day. Source: NYSE Rule 118.30 Also, remember that the dividend yield is expressed in annualized terms. So a 3% yield can only be fully realized by receiving all of the dividend payments made by the company for the year. You can, of course, forget about individual companies and just look for dividends to create your own effective yield over time. But, see the final point... Finally, if you keep buying and selling just to play games with the dividends, you're going to pay far more in transaction fees than you will earn in dividends. And, depending on your individual circumstances, you may end up paying more in capital gains taxes." The market is not stupid. It realises that a company is worth less after paying out dividends than before paying them. (It's obvious, since that company has just given out part of its earnings.) So after a company pays out dividends, its stock price normally drops approximately by the amount paid. Therefore if you buy, get the dividend, and immediately sell, under normal conditions you won't make any profit. The ex-dividend date, prevents this, but people are still able to do this and this is an investment strategy. There are some illiquid and immature markets where prices don't adjust.  In the options market people are able to find mispriced deep in the money calls to take advantage of the ex-dividend date. It is called dividend capture using covered calls. The rest of the market knows when the dividends are paid out, and that will be reflected naturally in the share price. That's why there is no way to consistently beat the market. Because the market is other human beings, who's sum of knowledge is greater than any individual. Everything in the stock market boils down to this in one way or another. Although the market  discussion by other answers is correct, the  tax structure of many developed nations (I am familiar with Canada in particular) offers a preferred tax rate for dividend income compared to taxable gains. Consequently, if your portfolio is large enough to make transaction fees a very small percentage rate, this is a viable investment strategy.  However, as the preferred tax rate for dividends typically will catch up to that for capital gains at some cut-off point, there is a natural limit on how much income can be favourably obtained in this way.  If you believe your portfolio might be large enough to benefit from this investment strategy, talk to a qualified investment advisor, broker, or tax consultant for the specifics for your tax jurisdiction. I remember my Finance Professor at b-school answering this question:   The next moment the dividend is paid the total market cap is decreased by the amount paid   This makes sense as cash leaves company, the value of the company is decreased by exactly the same amount. To summarise: the moment you paid dividend, the value of the stock is decreased by the same amount. This investment strategy may have tax advantages. In some countries, income received from dividends is taxed as income, whereas profits on share trades are capital gains. If you have already exceeded your tax-free income limit for the year, but not your capital gains tax allowance, it may be preferable to make a dealing profit rather than an investment income. These arrangements are called a bed-and-breakfast.
Ok you're looking at this in a very confusing way. First, as said by CapitalNumb3rs, the dividend yield is the dividends paid in the year as a percent of the stock price. Given this fact then if the stock price moves down and the dividend stays the same then the yield increases. Company's don't usually pay out on a yield basis, that's mostly just a calculation to measure how strong a dividend is. This could mean either A. The stock is underpriced and will rise which will lower the yield to a more normal level or B. the company is not doing as well and eventually the dividends will decrease to a point where the yield again looks more normal.   Second off let's look at it in a more realistic way that still takes into account your assumptions:  **YEAR 1** 1. Instead of assuming buying 35% let's put this into a share amount. Let's say there are 1,000,000 shares so you just bought 350k shares for $700k. You paid a price of $2/share. Let's assume the market decides that's a fair price and it stays that way through the end of year 1. This gives us a market capitalization of $2 million.  2. The dividend paid out at year 1 is $60k so you could calculate on a per share basis which would be a dividend of $60k / 1 million shares or a $0.06 dividend per share. Our stock price is still at $2.00 so our yield comes out to $0.06 / $2.00 or 3.0%  **YEAR 2** Assuming no additional shares issued there are still a total of 1 million shares outstanding. You owned 350k and now want to purchase another 50k (5% of outstanding share float). The market price you are able to purchase the 50k shares at has now changed which means that share price is now valued at $1.50 / share. We have a dividend paid out at $100k, which comes out to a dividend per share of $0.10. We have a share value of $1.50 and the $0.10 dividend per share giving us a new yield of 6.66%.   **CONCLUSION:** There are many factors that can cause a company's stock price to fluctuate, some of it is hype based but some of it is a result of material changes. In your case the stock went down 25%. In most scenarios where a stock would have that much decline it would likely either not have been paying a dividend in the first place or would maybe not be paying one for much longer. Most companies that pay dividends are larger and more mature companies with a steady, healthy and predictable cash flow. Also most companies that are that size would not trade a stock under $3.00, I know this is just an example but the scenario is definitely a bit extreme in terms of the price drop and dividend increase. Again the yield is just a calculation that depends on the dividend that is usually planned in advance and the stock price that can fluctuate for many reasons. I hope this made everything more clear and let me know if you have any other questions. The dividend goes to he who owns the stock when it goes ex-div. A buyer (the call buyer who exercises) will not exercise unless the stock plus dividend are in the money. Otherwise they'd be buying the stock at a premium.  I like the scenario your friend doesn't. If I can find a high dividend stock and sell the call for a decent price, I may get a great return on a stock that's gone down 5% over a year's time. If it goes up and called away, that's fine too, it means a profit. Why do people talk about stock that pay high dividends?  Traditionally people who buy dividend stocks are looking for income from their investments. Most dividend stock companies pay out dividends every quarter ( every 90 days). If set up properly an investor can receive a dividend check every month, every week or as often as they have enough money to stagger the ex-dates. There is a difference in high $$ amount of the dividend and the yield.  A $1/share dividend payout may sound good up front, but... how much is that stock costing you? If the stock cost you $100/share, then you are getting 1% yield. If the stock cost you $10/share, you are getting 10% yield.  There are a lot of factors that come into play when investing in dividend stocks for cash flow. Keep in mind why are you investing in the first place. Growth or cash flow. Arrange your investing around your major investment goals. Don't chase big dollar dividend checks, do your research and follow a proven investment plan to reach your goals safely. There are two main ways you can make money through shares: through dividends and through capital gains. If the company is performing well and increasing profits year after year, its Net Worth will increase, and if the company continues to beat expectations, then over the long term the share price will follow and increase as well. On the other hand, if the company performs poorly, has a lot of debt and is losing money, it may well stop paying dividends. There will be more demand for stocks that perform well than those that perform badly, thus driving the share price of these stocks up even if they don't pay out dividends. There are many market participants that will use different information to make their decisions to buy or sell a particular stock. Some will be long term buy and hold, others will be day traders, and there is everything in between. Some will use fundamentals to make their decisions, others will use charts and technicals, some will use a combination, and others will use completely different information and methods. These different market participants will create demand at various times, thus driving the share price of good companies up over time. The annual returns from dividends are often between 1% and 6%, and, in some cases, up to 10%. However, annual returns from capital gains can be 20%, 50%, 100% or more. That is the main reason why people still buy stocks that pay no dividends. It is my reason for buying them too. You only have to own it for a day (or rather for some amount of time before the close of trading the day before the ex-dividend date).  This is governed by exchange rules based on the date of record and payable date set by the company.  You might want to look at this article or this one for more details. It should be difficult to make money from changes due to the dividend distribution since it is well known and expected.  The exchanges have established rules for handling the various details that can come up, and traders account for the change where appropriate (as in option pricing).  Also, note that the favorable U.S. tax treatment of dividends requires a 60-day ownership period for the stock. Dividend yields are a product of the dollar amount paid to shareholders and the stock price. Dividends yields rise when a company is shunned by investors. It may be shunned because the earnings and/or dividend are at risk. Recent examples are SDRL and KMI. Most investors  would love an 8% yield so I would wonder why the stock is being ignored or shunned. The S&P 500 is an index, you can't buy shares of an index, but you can find index funds to invest in. Each company in that fund that pays dividends will do so on their own schedule, and the fund you've invested in will either distribute dividends or accumulate them (re-invest), this is pre-defined, not something they'd decide quarter to quarter. If the fund distributes dividends, they will likely combine the dividends they receive and distribute to you quarterly.  The value you've referenced represents the total annual dividend across the index, dividend yield for S&P500 is currently ~1.9%, so if you invested $10,000 a year ago in a fund that matched the S&P 500, you'd have ~$190 in dividend yield. Yield can be thought of as the interest rate you would receive from that investment in the form of a dividend for stocks or interest payments on a bond.  The yield takes into account the anticipated amount to be received per share/unit per year and the current price of the investment.   Of course, the yield is not a guaranteed return like a savings account.  If the investment yield is 4% when you buy, it can drop in value such that you actually lose money during your hold period, despite receiving income from the dividend or interest payments. "Not minutes, but hours.  The ""ex-dividend"" date is the deadline for acquiring a stock to receive a dividend. If you hold a stock at the beginning of this day, you will receive the dividend. So you could buy a stock right at the end of the day on the day before the ex-dividend date, and sell it the next day (on the ex-dividend date), and you would get your dividend. See this page from the SEC for more information.  The problem with this strategy, however, is that the value of the stock typically drops by the same amount as the dividend on that day. If you take a look at the historical price of the stock you are interested in, you'll see this. Of course, it makes sense why: a seller knows that selling before  the date results in a loss of the dividend, so they want a higher price to compensate. Likewise, a buyer on or after the date knows that the dividend is already gone, so they want to pay a lower price." "My broker offers the following types of sell orders: I have a strategy to sell-half of my position once the accrued value has doubled.  I take into account market price, dividends, and taxes (Both LTgain and taxes on dividends).  Once the market price exceeds the magic trigger price by 10%, I enter a ""trailing stop %"" order at 10%.  Ideally what happens is that the stock keeps going up, and the trailing stop % keeps following it, and that goes on long enough that accrued dividends end up paying for the stock.  What happens in reality is that the stock goes up some, goes down some, then the order gets cancelled because the company announces dividends or something dumb like that. THEN I get into trouble trying to figure out how to re-enter the order, maintaining the unrealized gain in the history of the trailing stop order.  I screwed up and entered the wrong type of order once and sold stock I didn't want to. Lets look at an example. a number of years ago, I bought some JNJ -- a hundred shares at 62.18.  - Accumulated dividends are 2127.75  - My spreadsheet tells me the ""double price"" is 104.54, and double + 10% is 116.16.  - So a while ago, JNJ exceeded 118.23, and I entered a Trailing Stop 10% order to sell 50 shares of JNJ.  The activation price was 106.41.  - since then, the price has gone up and down...  it reached a high of 126.07, setting the activation price at 113.45.  - Then, JNJ announced a dividend, and my broker cancelled the trailing stop order.  I've re-entered a ""Stop market"" order at 113.45.  I've also entered an alert for $126.07 -- if the alert gets triggered, I'll cancel the Market Stop and enter a new trailing stop." You only have to hold the shares at the opening of the ex-dividend date to get the dividends. So you can actually sell the shares on ex-dividend date and still get the dividends. Ex-dividend date occurs before the record date and payment date, so you will get the dividend even if you sold before the record date. The ex-dividend date is the first date on which you may sell without losing your dividend.  In this case that date is August 5th (thanks, Victor).  The price opens on the ex-dividend date lower than it closed on the previous day (by the amount of the dividend). Therefore you may sell any time on August 5th (including during pre-market trading) and still get the dividend. You must be the owner of the stock as of the end of after-hours trading on the 4th (and therefore overnight) in order to get the dividend. Intel's Dividend Dates The record date isn't important to your trading decision. Insiders are prevented from buying or selling shares except at certain periods right after information is disclosed publicly. But. People have bills to pay and kids to put through college and whatnot. So an insider can set up a plan where shares are sold on a specific schedule and they have no control over number of shares or timing. These plans (covered under rule 10b5-1) allow insiders to generate cash flow without immoderately benefiting from their inside information. Sales under these plans can mostly be ignored when trying to figure out the fortunes of a company from insider trades. Berkshire Hathaway would be a good example of a company that has yet to pay dividends, yet is a highly valued stock. A couple of key points here to note is how on the first hand you have that the dividend policy will never change, yet couldn't one argue that there will always be new investors wanting more shares and thus the price keeps going up until someone gains control and decides to issue dividends?  I'm just pointing out how on the one hand you are claiming a never changing and yet on the other thinking there will be a termination when the reality is that unless there is a zombie apocalypse of some form, life will continue and there will be new people to want to buy the stock and some people be willing to sell at the new prices. "Dividends are paid based on who owns the security on a designated day.  If a particular security pays once per year, you hold 364 days and sell on the day before the ""critical"" day, you get no dividend.  This is not special to 401(k) or to DRIP.  It's just how the system works. The ""critical"" day is the day before the posted ex-dividend date for the security. If you own at the end of that day, you get the dividend.  If you sell on that day or before, you do not. Your company changing providers is not in itself relevant.  The important factor is whether you can still hold your same investments in the new plan.  If not, you will not get the dividend on anything that you currently hold but ""sell"" due to the change in providers.  If you can, then you potentially get the dividend so long as there's no glitch in the transition. Incidentally, it works the other way too.  You might end up getting a dividend through the new plan for something that you did not hold the full year."
