At what price are dividends re-invested?
Keep in mind the ex-dividend date is different from the payable date (the day the dividend is paid). That means the market price will already have adjusted lower due to the dividend. Short answer: you get the lower price when reinvesting. So here's Vanguard's policy, it should be similar to most brokers: When reinvesting dividends, Vanguard Brokerage Services combines the   cash distributions from the accounts of all clients who have requested   reinvestment in the same security, and then uses that combined total   to purchase additional shares of the security in the open market.   Vanguard Brokerage will attempt to purchase the reinvestment shares by   entering a market order at the market opening on the payable date. The   new shares are divided proportionately among the clients' accounts, in   whole and fractional shares rounded to three decimal places. If the   total purchase can't be completed in one trade, clients will receive   shares purchased at the weighted average price paid by Vanguard   Brokerage Services. "If a stock is trading for $11 per share just before a $1 per share dividend is declared, then the share price drops to $10 per share immediately following the declaration. If you owned 100 shares (valued at $1100) before the dividend was declared, then you still own 100 shares (now valued at $1000). Generally, if the dividend is paid today, only the owners of shares as of yesterday evening (or the day before maybe) get paid the dividend. If you bought those 100 shares only this morning, the dividend gets paid to the seller (who owned the stock until yesterday evening), not to you. You just ""bought a dividend:"" paying $1100 for 100 shares that are worth only $1000 at the end of the day, whereas if you had just been a little less eager to purchase right now, you could have bought those 100 shares for only $1000. But, looking at the bright side, if you bought the shares earlier than yesterday, you get paid the dividend.  So, assuming that you bought the shares in timely fashion, your holdings just lost value and are worth only $1000.  What you do have is the promise that in a couple of days time, you will be paid $100 as the dividend, thus restoring the asset value back to what it was earlier.  Now, if you had asked your broker to re-invest the dividend back into the same stock, then, assuming that the stock price did not change in the interim due to normal market fluctuations, you would get another 10 shares for that $100 dividend making the value of your investment $1100 again (110 shares at $10 each), exactly what it was before the dividend was paid. If you didn't choose to reinvest the dividend, you would still have the 100 shares (worth $1000) plus $100 cash. So, regardless of what other investors choose to do, your asset value does not change as a result of the dividend.  What does change is your net worth because that dividend amount is taxable (regardless of whether you chose to reinvest or not) and so your (tax) liability just increased."
Wow I love some of these answers. Remember why you are investing in the first place.  For me I like Dividend stocks and Dividend Capturing. Here is why. With over 3500 dividend stock companies paying out dividends this year, that means I can get a dividend check almost every day. What about if the stock goes down you ask? Well out of these 3500 companies there is a small group of these stocks that have consistently increased their dividend payout to their investors for over 25 years and a smaller group that have been increasing every year their pay outs for over 50 years. Yes Kennedy was in office back then and to this day they consistently pay higher and higher dividend payments to their investors, every year... for 50 years.  As for the Dividend Capturing strategy, that allows me to collect up 10-20 checks per month with that little effort. As for the stock going down... Here is a little tidbit that most buyers overlook. Stock price is more or less the public's perception of the value of a certain company. Earnings, balance sheet, cash flow, market cap and a few other things in the quarterly report will give you a better answer to the value of a company. If stock price goes down while earning and market go keep going up... what does that tell you? "Isn't it true that on the ex-dividend date, the price of the stock goes down roughly the amount of the dividend? That is, what you gain in dividend, you lose in price drop. Yes and No. It Depends! Generally stocks move up and down during the market, and become more volatile on some news. So One can't truly measure if the stock has gone down by the extent of dividend as one cannot isolate other factors for what is a normal share movement. There are time when the prices infact moves up. Now would it have moved more if there was no dividend is speculative. Secondly the dividends are very small percentage compared to the shares trading price. Generally even if 100% dividend are announced, they are on the share capital. On share prices dividends would be less than 1%. Hence it becomes more difficult to measure the movement of stock. Note if the dividend is greater than a said percentage, there are rules that give guidelines to factor this in options and other area etc. Lets not mix these exceptions. Why is everyone making a big deal out of the amount that companies pay in dividends then? Why do some people call themselves ""dividend investors""? It doesn't seem to make much sense. There are some set of investors who are passive. i.e. they want to invest in good stock, but don't want to sell it; i.e. more like keep it for long time. At the same time they want some cash potentially to spend; similar to interest received on Bank Deposits. This class of share holders, it makes sense to invest into companies that give dividends, as year on year they keep receiving some money. If they on the other hand has invested into a company that does not give dividends, they would have to sell some units to get the same money back. This is the catch. They have to sell in whole units, there is brokerage, fees, etc, there are tax events. Some countries have taxes that are more friendly to dividends than capital gains. Thus its an individual choice whether to invest into companies that give good dividends or into companies that don't give dividends.  Giving or not giving dividends does not make a company good or bad." It depends on your investment profile but basically, dividends increase your taxable income. Anyone making an income will effectively get 'lower returns' on their investments due to this effect. If you had the choice between identical shares that either give a dividend or don't, you'll find that stock that pays a dividend has a lower price, and increases in value more slowly than stock that doesn't. (all other things being equal)  There's a whole bunch of economic theory behind this but in short, the current stock price is a measure of how much the company is worth combined with an estimation of how much it will be worth in the future (NPV of all future dividends is the basic model). When the company makes profit, it can keep those profits, and invest in new projects or distribute a portion of those profits to shareholders (aka dividends). Distributing the value to shareholders reduces the value of the company somewhat, but the shareholders get the money now. If the company doesn't give dividends, it has a higher value which will be reflected in a higher stock price.  So basically, all other things being equal (which they rarely are, but I digress) the price and growth difference reflects the fact that dividends are paying out now. (In other words, if you wanted non-dividend shares you could get them by buying dividend shares and re-investing the dividend as new shares every time there was a payout, and you could get dividend-share like properties by selling a percentage of non-dividend shares periodically). Dividend income is taxable as part of your income right away, however taxes on capital gains only happen when you sell the asset in question, and also has a lower tax rate. If you buy and hold Berkshire Hatheway, you will not have to pay taxes on the gains you get until you decide to sell the shares, and even then the tax rate will be lower. If you are investing for retirement, this is great, since your income from other sources will be lower, so you can afford to be taxed then. In many jurisdictions, income from capital gains is subject to a different tax rate than the rest of your income, for example in the US for most people with money to invest it's either 15% or 20%, which will be lower than normal income tax would be (since most people with money to invest would be making enough to be in a higher bracket). Say, for example, your income now is within the 25% bracket. Any dividend you get will be taxed at that rate, so let's say that the dividend is about 2% and the growth of the stock is about 4%. So, your effective growth rate after taxation is 5.5% -- you lose 0.5% from the 25% tax on the dividend. If, instead, you had stock with the same growth but no dividend it would grow at a rate of 6%. If you never withdrew the money, after 20 years, $1 in the dividend stock would be worth ~$2.92 (1.055^20), whereas $1 in the non-dividend stock would be worth ~$3.21 (1.06^20). You're talking about a difference of 30 cents per dollar invested, which doesn't seem huge but multiply it by 100,000 and you've got yourself enough money to renovate your house purely out of money that would have gone to the government instead. The advantage here is if you are saving up for retirement, when you retire you won't have much income so the tax on the gains (even ignoring the capital gains effect above) will definitely be less then when you were working, however if you had a dividend stock you would have been paying taxes on the dividend, at a higher rate, throughout the lifetime of the investment.  So, there you go, that's what Mohnish Pabrai is talking about. There are some caveats to this. If the amount you are investing isn't large, and you are in a lower tax bracket, and the stock pays out relatively low dividends you won't really feel the difference much, even though it's there. Also, dividend vs. no dividend is hardly the highest priority when deciding what company to invest in, and you'll practically never be able to find identical companies that differ only on dividend/no dividend, so if you find a great buy you may not have a choice in the matter.  Also, there has been a trend in recent years to also make capital gains tax progressive, so people who have a higher income will also pay more in capital gains, which negates part of the benefit of non-dividend stocks (but doesn't change the growth rate effects before the sale).  There are also some theoretical arguments that dividend-paying companies should have stronger shareholders (since the company has less capital, it has to 'play nice' to get money either from new shares or from banks, which leads to less risky behavior) but it's not so cut-and-dried in real life. There are 3 options (option 2 may not be available to you) When you invest 18,000 in a Traditional 401k, you don't pay taxes on the 18k the year you invest, but you pay taxes as you withdraw.  There's a Required Minimum Distribution required after age 70.  If your income is low enough, you won't pay taxes on your withdrawals.  Otherwise, you pay as if it is income.  However, you don't pay payroll tax (Social Security / Medicare) on the withdrawals.  You pay no tax until you withdraw. When you invest 18,000 in a Roth 401k, you pay income tax on the 18,000 in the year it's invested, but you pay nothing after that. When you invest 18,000 in a taxable investment account, you pay income tax on that 18,000 in the year it's invested, you pay tax on dividends (even if they're re-invested), and then you pay capital gains tax when you withdraw. But remember, tax rules and tax rates are only good so long as Congress doesn't change the applicable laws. It looks like you need a lot more education on the subject. I suggest you pick up a book on investing and portfolio management to get a first idea. Dividend yields are currently way below 5% on blue chips. Unlike coupons from fixed income instruments (which, in the same risk category, pay a lot less), dividend yields are not guaranteed and neither is the invested principal amount.  In either case, your calculation is far away from reality.  Sure, there are investments (such as the mentioned direct investments in companies or housings in emerging economies) that can potentially earn you two digit percentage returns. Just remember: risk always goes both ways. A higher earning potential means higher loss potential. Also, a direct investment is a lot less liquid than an investment on a publicly quoted high turnover market place. If you suddenly need money, you really don't want to be pressed to sell real estate in an emerging market (keyword: bid ask spread). My advice: the money that you can set aside for the long term (10 years plus), invest it in stock ETFs, globally. Everything else should be invested in bond funds or even deposits, depending on when you will need the access. As others have pointed out, consider getting professional advice. "In addition to the other answers it's also noteworthy that the stock exchanges themselves adjust the price quotes via their ex-div mechanism.  All limit orders present in the book when the stock goes ex-div will be adjusted by the dividend. Which means you can't even get ""accidentally"" filled in the very unlikely case that everyone forgot to adjust their quotes." tl;dr: The CNN Money and Yahoo Finance charts are wildly inaccurate. The TD Ameritrade chart appears to be accurate and shows returns with reinvested dividends. Ignoring buggy data, CNN most likely shows reinvested dividends for quoted securities but not for the S&P 500 index. Yahoo most likely shows all returns without reinvested dividends. Thanks to a tip from Grade Eh Bacon, I was able to determine that TD Ameritrade reports returns with reinvested dividends (as it claims to do). Eyeballing the chart, it appears that S&P 500 grew by ~90% over the five year period the chart covers. Meanwhile, according to this S&P 500 return estimator, the five year return of S&P 500, with reinvested dividends, was 97.1% between July 2012 to July 2017 (vs. 78.4% raw returns). I have no idea what numbers CNN Money is working from, because it claims S&P 500 only grew about 35% over the last five years, which is less than half of the raw return. Ditto for Yahoo, which claims 45% growth. Even stranger still, the CNN chart for VFINX (an S&P 500 index fund) clearly shows the correct market growth (without reinvesting dividends from the S&P 500 index), so whatever problem exists is inconsistent:  Yahoo also agrees with itself for VFINX, but comes in a bit low even if your assume no reinvestment of dividends (68% vs. 78% expected); I'm not sure if it's ever right.  By way of comparison, TD's chart for VFINX seems to be consistent with its ABALX chart and with reality:  As a final sanity check, I pulled historical ^GSPC prices from Yahoo Finance. It closed at $1406.58 on 27 Aug 2012 and $2477.55 on 28 Aug 2017, or 76.1% growth overall. That agrees with TD and the return calculator above, and disagrees with CNN Money (on ABALX). Worse, Yahoo's own charts (both ABALX and VFINX) disagree with Yahoo's own historical data. Good question, here are some possible answers: Its a Good Idea There is probably some validity to the statictics and having money invested, generally speaking, has proven far more valuable than having it sit in a savings account. It tends to reinforce strength Suppose you own two stocks, one that is a great performer, and one that isn't.  Generally speaking the high performer will pay out more, and if you reinvest more into that stock, you will be wealthier if you contributed equally to both stocks. You might forget People tend to forget to do things that are not in the forefront, and reinvestment is one of those things that slip people's mind.  One of the wealth building tools that people universally recommend is automation.  Reinvesting is a way to automate one aspect of one's financial life.   You might spend it on something else If you put the dividends into your checking account, there is a non-zero chance that it might get put towards something else.  Better to have it out of sight and mind and invested. They make money Generally speaking, the more money you have in a brokerage account, the more the brokerage makes.   So it is good for them, as well as yourself. While there is some attraction to being able to see a balance that is the result of dividend investments, its just far better to have them be poured right back into whatever investment seem appropriate.
