Where are open-end funds traded?
"I assume that mutual funds are being discussed here. As Bryce says, open-ended funds are bought from the mutual fund company and redeemed from the fund company.  Except in very rare circumstances,  they exist only  as bits in the fund company's computers and not as share certificates (whether paper or electronic) that can be delivered from the selling broker to the buying broker on a stock exchange. Effectively, the fund company is the sole market maker: if you want to buy, ask the fund company at what price it will sell them to you (and it will tell you the answer only after 4 pm that day when a sale at that price is no longer possible unless you committed to buy, say, 100 shares and authorized the fund company to withdraw the correct amount from your bank account or other liquid asset after the price was known).  Ditto if you want to sell: the mutual fund company will tell you what price it will give you only after 4 pm that day and you cannot sell at that price unless you had committed to accept whatever the company was going to give you for your shares (or had said ""Send me $1000 and sell as many shares of mine as are needed to give me proceeds of $1000 cash."")" Close-end funds just means there's a fixed number of shares available, so if you want to buy some you must purchase from other existing owners, typically through an exchange. Open-end funds mean the company providing the shares is still selling them, so you can buy them directly from the company.  Some can also be traded on exchanges as well.
Bond ETFs are just another way to buy a bond mutual fund.  An ETF lets you trade mutual fund shares the way you trade stocks, in small share-size increments.  The content of this answer applies equally to both stock and bond funds. If you are intending to buy and hold these securities, your main concerns should be purchase fees and expense ratios.  Different brokerages will charge you different amounts to purchase these securities.  Some brokerages have their own mutual funds for which they charge no trading fees, but they charge trading fees for ETFs.  Brokerage A will let you buy Brokerage A's mutual funds for no trading fee but will charge a fee if you purchase Brokerage B's mutual fund in your Brokerage A account. Some brokerages have multiple classes of the same mutual fund.  For example, Vanguard for many of its mutual funds has an Investor class (minimum $3,000 initial investment), Admiral class (minimum $10,000 initial investment), and an ETF (share price as initial investment).  Investor class has the highest expense ratio (ER).  Admiral class and the ETF generally have much lower ER, usually the same number.  For example, Vanguard's Total Bond Market Index mutual fund has Investor class (symbol VBMFX) with 0.16% ER, Admiral (symbol VBTLX) with 0.06% ER, and ETF (symbol BND) with 0.06% ER (same as Admiral).  See Vanguard ETF/mutual fund comparison page.  Note that you can initially buy Investor class shares with Vanguard and Vanguard will automatically convert them to the lower-ER Admiral class shares when your investment has grown to the Admiral threshold. Choosing your broker and your funds may end up being more important than choosing the form of mutual fund versus ETF.  Some brokers charge very high purchase/redemption fees for mutual funds.  Many brokers have no ETFs that they will trade for free.  Between funds, index funds are passively managed and are just designed to track a certain index; they have lower ERs.  Actively managed funds are run by managers who try to beat the market; they have higher ERs and tend to actually fall below the performance of index funds, a double whammy.

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. "You mentioned three concepts: (1) trading (2) diversification (3) buy and hold.   Trading with any frequency is for people who want to manage their investments as a hobby or profession.  You do not seem to be in that category.  Diversification is a critical element of any investment strategy.  No matter what you do, you should be diversified.  All the way would be best (this means owning at least some of every asset out there).  The usual way to do this is to own a mutual or index fund.  Or several.  These funds own hundreds or thousands of stocks, so that buying the fund instantly diversifies you. Buy and hold is the only reasonable approach to a portfolio for someone who is not interested in spending a lot of time managing it.  There's no reason to think a buy-and-hold portfolio will underperform a typical traded portfolio, nor that the gains will come later.  It's the assets in the portfolio that determine how aggressive/risky it is, not the frequency with which it is traded. This isn't really a site for specific recommendations, but I'll provide a quick idea:  Buy a couple of index funds that cover the whole universe of investments.  Index funds have low expenses and are the cheapest/easiest way to diversify.  Buy a ""total stock market"" fund and a ""total bond fund"" in a ratio that you like.  If you want, also buy an ""international fund.""  If you want specific tickers and ratios, another forum would be better(or just ask your broker or 401(k) provider).  The bogleheads forum is one that I respect where people are very happy to give and debate specific recommendations. At the end of the day, responsibly managing your investment portfolio is not rocket science and shouldn't occupy a lot of time or worry.  Just choose a few funds with low expenses that cover all the assets you are really interested in, put your money in them in a reasonable-ish ratio (no one knows that the best ratio is) and then forget about it." "Prices reflect all available information. (Efficient markets hypothesis) A lot can happen between the time a stock closes on one day and opens on another. Particularly in a heavily traded stock such as IBM. Basically, you have a different ""information set"" the following day, which implies a different price. The instances where you are most likely to have a stock where the price opens at the same price is at the previous close is a thinly traded stock on which you have little information, meaning that the ""information set"" changes less from day to day." Significantly less effort to buy into any of several international bond index funds. Off the top of my head, VTIBX. "I'm assuming the question is about how to compare two ETFs that track the same index. I'd look at (for ETFs -- ignoring index funds): So, for example you might compare SPY vs IVV: SPY has about 100x the volume. Sure, IVV has 2M shares trading, so it is liquid ""enough"". But the bigger volume on SPY might matter to you if you use options: open interest is as much as 1000x more on SPY. Even if you have no interest in options, the spreads on SPY are probably going to be slightly smaller. They both have 0.09% expense ratios. When I looked on 2010-9-6, SPY was trading at a slight discount, IVV was at a slight premium. Looking for any sort of trend is left as an exercise to the reader... Grab the prospectus for each to examine the rules they set for fund makeup. Both come from well-known issuers and have a decent history. (Rather than crazy Uncle Ed's pawn shop, or the Central Bank of Stilumunistan.) So unless you find something in the SPY prospectus that makes you queasy, the higher volume and equal expense ratios would seem to suggest it over IVV. The fact that it is at a (tiny) discount right now is a (tiny) bonus." "I recommend avoiding trading directly in commodities futures and options.  If you're not prepared to learn a lot about how futures markets and trading works, it will be an experience fraught with pitfalls and lost money – and I am speaking from experience. Looking at stock-exchange listed products is a reasonable approach for an individual investor desiring added diversification for their portfolio.  Still, exercise caution and know what you're buying. It's easy to access many commodity-based exchange-traded funds (ETFs) on North American stock exchanges.  If you already have low-cost access to U.S. markets, consider this option – but be mindful of currency conversion costs, etc. Yet, there is also a European-based company, ETF Securities, headquartered in Jersey, Channel Islands, which offers many exchange-traded funds on European exchanges such as London and Frankfurt.  ETF Securities started in 2003 by first offering a gold commodity exchange-traded fund. I also found the following: London Stock Exchange: Frequently Asked Questions about ETCs.  The LSE ETC FAQ specifically mentions ""ETF Securities"" by name, and addresses questions such as how/where they are regulated, what happens to investments if ""ETF Securities"" were to go bankrupt, etc. I hope this helps, but please, do your own due diligence."
