When to buy and sell bonds
Why does selling a bond drive up the yield? The bond will pay back a fixed amount when it comes due. The yield is a comparison of what you pay for the bond and what will be repaid when it matures (assuming no default). Why does the yield go up if the country is economically unstable? If the country's economy is unstable, that increases the chance that they will default and not pay the full value of the bonds when they mature. People are selling them now at a loss instead of waiting for a default later for a greater loss. So if you think Greece is not going to default as it's highly likely a country would completely default, wouldn't it make sense to hold onto the bonds? Only if you also think that they will pay back the full value at maturity. It's possible that they pay some, but not all. It's also possible that they will default. It's also possible that they will get kicked out of the Euro and start printing Drachmas again, and try to pay the bonds back with those which could devalue the bonds through inflation. The market is made of lots of smart people. If they think there are reasons to worry, there probably are. That doesn't mean they can predict the future, it just means that they are pricing the risk with good information. If you are smarter than the herd, by all means, bet against them and buy the bonds now. It can indeed be lucrative if you are right, and they are wrong. "Why does the yield go up if the country is economically unstable? The yield will rise when instability increases because the risk of default increases.  If the case of Greece, the instability of government finances resulted in a 50% ""haircut"" for bond holders in 2011.  In other words, bond holders suffered a 50% write down in the nominal value of their bonds.  This means that holding these bonds until maturity will mean they will only receive half of the original nominal value of the bond, and that is assuming no further write downs occur. Why does selling a bond drive up the yield? Significant selling of bonds means that sellers are worried about future prospects.  Sellers will outnumber buyers, so sellers will have to reduce their offer price in order to attract new buyers. So if you think Greece is not going to default as it's highly likely a country would completely default, wouldn't it make sense to hold onto the bonds? If you think that it is highly unlikely that Greece will default and the prices and yields are attractive, then Greek bonds may look like an attractive investment. However, keep in mind the fate of bond holders in 2011.  They were attracted to Greek bonds by the price and yield, but they suffered a 50% haircut."
Perfect super clear, thank you /u/xlct2  So it is like you buy a bond for $X, start getting interest, sell bond for $X :)  I was thinking there could be a possibility of a bond working like a loan from a bank, that you going paying as time goes by :D "You have a good thing going. One of the luxuries of being invested in an index fund for the long term is that you don't have to sweat the inevitable short term dips in the market. Instead, look at the opportunity that presents itself on market dips: now your monthly investment is getting in at a lower price. ""Buy low, sell high."" ""Don't lose money."" These are common mantras for long term investment mentality. 5-8 years is plenty of time -- I'd call it ""medium-term"". As you get closer to your goals (~2-3 years out) you should start slowly moving money out of your index fund and start dollar cost averaging out into cash or short-term bonds (but that's another question). Keep putting money in, wait, and sell high. If it's not high, wait another year or two to buy the house. A lot of people do the opposite for their entire lives: buying high, panic selling on the dips, then buying again when it goes up. That's bad! I recommend a search on ""dollar cost averaging"", which is exactly what you are doing right now with your monthly investments." who issued stock typically support it when the stock price go down.  No, not many company do that as it is uneconomical for them to do so. Money used up in buying back equity is a wasteful use of a firm's capital, unless it is doing a buyback to return money to shareholders. Does the same thing happen with government bonds?  Not necessarily again here. Bond trading is very different from equities trading. There are conditions specified in the offer document on when an issuer can recall bonds(to jack up the price of an oversold bond), even government bonds have them.  The actions of the government has a bigger ripple effect as compared to a firm. The government can start buying back bonds to increase it's price, but it will stoke inflation because of the increase in the supply of money in the market, which may or mayn't be desirable. Then again people holding the bond would have to incentivized to sell the bond. Even during the Greek fiasco, the Greek government wasn't buying Greek bonds as it had no capital to buy. Printing more euros wasn't an option as no assets to back the newly printed money and the ECB would have stopped them from being accepted.  And generally buying back isn't useful, because they have to return the principal(which might run into billions, invested in long term projects by the government and cannot be liquidated immediately) while servicing a bond is cheaper and investing the proceeds from the bond sale is more useful while being invested in long term projects. The government can just roll over the bonds with a new issue and refrain from returning the capital till it is in a position to do so. "In a cap-weighted fund, the fund itself isn't buying or selling at all (except to support redemptions or purchases of the fund). As the value of a stock in the index goes up, then its value in the fund goes up naturally. This is the advantage of a cap-weighted fund, that it doesn't have to trade (buy and sell), it just sits on the stocks. That makes a cap-weighted fund inexpensive (low trading costs) and tax-efficient (doesn't trigger capital gains due to sales). The buying high and selling low referred to by ""fundamental indexation"" advocates like Wisdom Tree is buying high and selling low on the part of the investor. That is, when you purchase the market-cap-weighted fund, at that time that you purchase, you will spend more on the higher-priced stocks, just because they account for more of the value of the fund, and less money goes to the cheaper stocks which account for less of the value of the fund. In the prospectus for a fund they should tell you which index they use, and if the prospectus doesn't describe the weighting of the index, you could do a web search for the index name and find out how that index is constructed. A market-cap-weighted fund is the standard kind of weighting which is what you get if you buy the stocks in the index and then hold them without buying or selling. Most of the famous indexes (e.g. S&P500) are cap-weighted, with the notable exception of the Dow Jones Industrial Average which is ""price-weighted"" http://en.wikipedia.org/wiki/Price-weighted_index. Price-weighting is just an archaic tradition, not something one would use for a new index design today. A fund weighted by ""fundamentals"" or equal-weighted, rather than cap-weighted, is effectively doing a kind of rebalancing, selling what's gone up to buy more of what's gone down. Rather than buying an exotic fund, you could get a similar effect by buying a balanced fund (one that mixes stocks and bonds). Then when stocks go up, your fund would sell them and buy bonds, and the fund would sell the most of the highest-market-cap stocks that make up more of the index. And vice versa of course. But the fundamental-weighted funds are fine, the more important considerations include your stocks vs. bonds percentages (asset allocation) and whether you make irrational trades instead of sticking to a plan." Buy low, sell high. I think a lot of people apply that advice wrongly. Instead of using this as advice about when to buy and when to sell, you should use it as advice about when not to buy and when not to sell. Don't buy when P/Es cannot support the current stock price. Don't sell when stocks have already fallen due to a market panic. Don't follow the herd or you will get trampled when they reverse direction in a panic.  If you are smart enough to sell ahead of the panics, more power to you, but you should be using more than a 52-week high on a graph to make that decision. Rebalancing your portfolio doesn't have to include selling.  You could simply adjust your buying to keep your portfolio in balance.  If you portfolio has shifted from 50% stocks and 50% bonds to 75% stocks and 25% bonds, you can just only use new savings to buy bonds, until you are back at 50-50. Remember to take into account taxes if you are thinking of selling to rebalance in taxable accounts. The goal of rebalancing is to keep your exposures the way that you want them.  Assuming that you had a good reason to have a portfolio of 50% stocks and 50% bonds, you probably want to keep your portfolio similar in the future.  If you end up with a portfolio of 75% stocks and 25% bonds due to stock market fluctuations, the exposure and the risk / return profile of your portfolio will have changed, and it's probably not something that you want. You don't want to rebalance just for the sake of rebalancing either.  There can be costs to rebalancing (taxes, transaction fees, etc...) and these aren't always worth the effort.  That's why you don't need to rebalance every month or if your portfolio has shifted from 50/50 to 51/49. I take a look at my portfolio once a year, and adjust my automated investments so that by the end of the next year I'm back to the ratio I want. Bond information is much tougher to get.  Try to find access to a Bloomberg terminal.  Maybe you have a broker that can do the research for you, maybe your local university has one in their business school, maybe you know someone that works for a bank/financial institution or some other type of news outlet.   Part of the reason for the difference in ease of access to information is that bond markets are dominated by institutional investors.  A $100 million bond issues might be 90% owned by 10-20 investors (banks, insurance co's, mutual funds, etc.) that will hold the bonds to maturity and the bonds might trade a few times a month/year.  On the other hand a similar equity offering may have several hundred or thousand owners with daily trading, especially if it's included in an active stock index. That being said, you can get some information on Fidelity's website if you have an account, but I think their junk data is limited.  Good luck with the hunt. When the market moves significantly, you should rebalance your investments to maintain the diversification ratios you have selected. That means if bonds go up and stocks go down, you sell bonds and buy stocks (to some degree), and vice versa. Sell high to buy low, and remember that over the long run most things regress to the mean.
