Why would a mutual fund plummet on the same day it pays its annual distribution & capital gains? [duplicate]
The price of a share of a mutual fund is its Net Asset Value (nav). Before the payout of dividends and capital gain distribution, the fund was holding both stock shares and cash that resulted from dividends and capital gains. After the payout, a share only holds the stock. Therefore once the cash is paid out the NAV must drop by the same amount as was paid out per share. Thus of course assumes no other activity or valuation changes of the underlying assets. Regular market activity will obscure what the payout does to the NAV.
If you put it in a normal account it is (1) taxed as ordinary income now and then (2) any growth is taxed again at the capital gains rate.  Additionally, (3) any dividends will be taxed each year.  If you put it in a 401(k), you will only be taxed once, at the ordinary income rate.   Mathematically, if you start with X and have a regular tax rate of t and capital gains rate of g and your investments return r and there are n years to retirement, then your total wealth if you put it in a mutual fund (ignoring annual taxes on dividends) will be While if you used a 401(k) it would simply be The whole g term (along with any annual taxes on dividends) is gone in the second case and that's potentially a lot of taxes.  The 401(k) is much better in terms of total wealth unless tax rates dramatically rise between now and when you retire so that the t in the second case is much higher than in the first. This is virtually never the case for people retiring now.  Of course, what tax rates the future holds, we do not know. A mutual fund has several classes of shares that are charged different fees. Some shares are sold through brokers and carry a sales charge (called load) that compensates the broker in lieu of a fee that the broker would charge the client for the service.  Vanguard does not have sales charge on its funds and you don't need to go through a broker to buy its shares; you can buy directly from them.  Admiral shares of Vanguard funds are charged lower annual expenses than regular shares (yes, all mutual funds charge expenses for fund adninistration that reduce the return that you get, and Vanguard has some of the lowest expense ratios) but Admiral shares are available only for large investments, typically $50K or so.  If you have invested in a Vanguard mutual fund, your shares can be set to automatically convert to Admiral shares when the investment reaches the right level. A mutual fund manager can buy and sell stocks to achieve the objectives of the fund, so what stockes you are invested in as a share holder in a mutual fund will typically be unknown to you on a day-to-day basis.  On the other hand, Exchange-traded funds (ETFs) are fixed baskets of stocks, and you can buy shares in the ETF.  These shares are bought and sold through a broker (so you pay a transaction fee each time) but expenses are lower since there is no manager to buy and sell stocks: the basket is fixed. Many ETFs follow specific market indexes (e.g. S&P 500).  Another difference between ETFs and mutual funds is that you can buy and sell ETFs at any time of the day just as if you could if you held stocks. With mutual funds, any buy and sell requests  made during the day are processed at the end of the day and the value of the shares that you buy or sell is determined by the closing price of the stocks held by the mutual fund.  With ETFs, you are getting the intra-day price at the time the buy or sell order is executed by your broker. "While nothing is guaranteed - any stock market or country could collapse tomorrow - if you have a fairly long window (15+ years is certainly long), ETFs are likely to earn you well above inflation.  Looking at long term ETFs, you typically see close to 10% annual growth over almost any ten year period in the US, and while I don't know European indexes, they're probably well above inflation at least. The downside of ETFs is that your money is somewhat less liquid than in a savings account, and any given year you might not earn anything - you easily could lose money in a particular year.  As such, you shouldn't have money in ETFs that you expect to use in the next few months or year or even a few years, perhaps. But as long as you're willing to play the long game - ie, invest in ETF, don't touch it for 15 years except to reinvest the dividends - as long as you go with someone like Vanguard, and use a very low expense ratio fund (mine are 0.06% and 0.10%, I believe), you are likely in the long term to come out ahead.  You can diversify your holdings - hold 10% to 20% in bond funds, for example - if you're concerned about risk; look at how some of the ""Target"" retirement funds allocate their investments to see how diversification can work [Target retirement funds assume high risk tolerance far out and then as the age grows the risk tolerance drops; don't invest in them, but it can be a good example of how to do it.]   All of this does require a tolerance of risk, though, and you have to be able to not touch your funds even if they go down - studies have repeatedly shown that trying to time the market is a net loss for most people, and the best thing you can do when your (diverse) investments go down is stay neutral (talking about large funds here and not individual stocks). I think this answers 3 and 4.   For 1, share price AND quantity matter (assuming no splits).  This depends somewhat on the fund; but at minimum, funds must dividend to you what they receive as dividends.  There are Dividend focused ETFs, which are an interesting topic in themselves; but a regular ETF doesn't usually have all that large of dividends.  For more information, investopedia has an article on the subject.  Note that there are also capital gains distributions, which are typically distributed to help offset capital gains taxes that may occur from time to time with an ETF.  Those aren't really returns - you may have to hand most or all over to the IRS - so don't consider distributions the same way. The share price tracks the total net asset value of the fund divided by the number of shares (roughly, assuming no supply/demand split).  This should go up as the stocks the ETF owns go up; overall, this is (for non-dividend ETFs) more often the larger volatility both up and down. For Vanguard's S&P500 ETF which you can see here, there were about $3.50 in dividends over 2014, which works out to about a 2% return ($185-$190 share price).  On the other hand, the share price went from around $168 at the beginning of 2014 to $190 at the end of 2014, for a return of 13%.   That was during a 'good' year for the market, of course; there will be years where you get 2-3% in dividends and lose money; in 2011 it opened at 116 and closed the year at 115 (I don't have the dividend for that year; certainly lower than 3.5% I'd think, but likely nonzero.) The one caveat here is that you do have stock splits, where they cut the price (say) in half and give you double the shares.  That of course is revenue neutral - you have the same value the day after the split as before, net of market movements. All of this is good from a tax point of view, by the way; changes in price don't hit you until you sell the stock/fund (unless the fund has some capital gains), while dividends and distributions do.  ETFs are seen as 'tax-friendly' for this reason. For 2, Vanguard is pretty good about this (in the US); I wouldn't necessarily invest monthly, but quarterly shouldn't be a problem.  Just pay attention to the fees and figure out what the optimal frequency is (ie, assuming 10% return, what is your break even point).  You would want to have some liquid assets anyway, so allow that liquid amount to rise over the quarter, then invest what you don't immediately see a need to use. You can see here Vanguard in the US has no fees for buying shares, but has a minimum of one share; so if you're buying their S&P500 (VOO), you'd need to wait until you had $200 or so to invest in order to invest additional funds." A mutual fund makes distributions of its dividends and capital gains, usually once a year, or seminanually or quarterly or monthly etc; it does not distribute any capital losses to its shareholders but holds them for offsetting capital gains in future years, (cf, this answer of mine to a different question). A stock pays  dividends; a stock neither has nor does it  distribute capital gains: you get capital gains (or losses) when you sell the shares of the stock, but these are not called distributions of any kind. Similarly, you incur capital gains or losses when you  redeem shares of mutual funds but these are not called distributions  either. Note that non-ETF mutual fund shares are generally not bought and sold on stock exchanges; you buy shares directly from the fund and you sell shares back (redeem them) directly to the fund.  All of the above transactions are taxable events for the year to you unless the shares are being held in a tax-deferred account or are tax-free for other reasons (e.g. dividends from a municipal bond fund). Two reasons why I think that's irrelevant: First, if it was on 3/31/2012 (two other sources say it was actually 4/3/2012), why the big jump two trading days later? Second, the stock popped up from $3.10 to $4.11, then over the next several trading days fell right back to $3.12. If this were about the intrinsic value of the company, I'd expect the stock to retain some value. There are very strict regulations that requires the assets which a fund buys on behalf of its investors to be kept completely separate from the fund's own assets (which it uses to pay its expenses), except for the published fees. Funds are typically audited regularly to ensure this is the case. So the only way in which a default of the fund could cause a loss of invstor money would be if the fund managers broke the regulations and committed various crimes. I've never heard of this actually happening to a normal mutual fund. There is of course also a default risk when a fund buys bonds or other non-equity securities, and this may sometimes be non-obvious. For example, some ETFs which are nominally based on a stock index don't actually buy stocks; instead they buy or sell options on those stocks, which involves a counterparty risk. The ETF may or may not have rules that limit the exposure to any one counterparty. Purchases and sales from the same trade date will both settle on the same settlement date. They don't have to pay for their purchases until later either. Because HFT typically make many offsetting trades -- buying, selling, buying, selling, buying, selling, etc -- when the purchases and sales settle, the amount they pay for their purchases will roughly cancel with the amount they receive for their sales (the difference being their profit or loss). Margin accounts and just having extra cash around can increase their ability to have trades that do not perfectly offset. In practice, the HFT's broker will take a smaller amount of cash (e.g. $1 million) as a deposit of capital, and will then allow the HFT to trade a larger amount of stock value long or short (e.g. $10 million, for 10:1 leverage). That $1 million needs to be enough to cover the net profit/loss when the trades settle, and the broker will monitor this to ensure that deposit will be enough. It may be true for a bond fund.  But it is not true for bond etf.  Bond etf will drop by the same amount when it distribute dividend on ex-dividend date.
