Which field should I use for getting the income yield of this bond ETF?
What you want is the distribution yield, which is 2.65. You can see the yield on FT as well, which is listed as 2.64. The difference between the 2 values is likely to be due to different dates of updates. http://funds.ft.com/uk/Tearsheet/Summary?s=CORP:LSE:USD
Very rarely would an investor be happy with a 4% yield independent of anything else that might happen in the future. For example, if in 3 years for some reason or other inflation explodes and 30 year bond yields go up to 15% across the board, they would be kicking themselves for having locked it up for 30 years at 4%. However, if instead of doing that the investor put their money in a 3 year bond at 3% say, they would have the opportunity to reinvest in the new rate environment, which might offer higher or lower yields. This eventually leads fixed income investors to have a bond portfolio in which they manage the average maturity of their bond portfolio to be somewhere between the two extremes of investing it all in super short term/ low yield money market rates vs. super long term bonds. As they constantly monitor and manage their maturing investments, it inevitably leads them to managing interest rate risk as they decide where to reinvest their incremental coupons by looking at the shape of the yield curve at the time and determining what kind of risk/reward tradeoffs they would have to make. "Bonds might not be simple, but in general there are only a few variables that need to be understood: bid, coupon (interest) rate, maturity, and yield.  Bond tables clearly lay those out, and if you're talking about government bonds a lot of things (like convertibles) don't apply (although default is still a concern). This might be overly simplistic, but I view ETF's primarily as an easy way to bring somewhat esoteric instruments (like grain futures) into the easily available markets of Nasdaq and the NYSE. That they got ""enhanced"" with leveraged funds and the such is interesting, but perhaps not the original intent of the instrument.  Complicating your situation a bit more is the fee that gets tacked onto the ETF. Even Vanguard government bond funds hang out north of 0.1%. That's not huge, but it's not particularly appealing either considering that (unlike rounding up live cattle futures), it's not that much work to buy US government bonds, so the expense might not seem worth it to someone who's comfortable purchasing the securities directly.  I'd be interested to see someone else's view on this, but in general I'd say that if you know what you want and know how to buy it, the government bond ETF becomes a lot less relevant as the liquidity offered (including the actual ""ease of transacting"") seem to to be the biggest factors in favor. From Investopedia's description: The bond ETF is an exciting new addition to the bond market, offering   an excellent alternative to self-directed investors who, looking for   ease of trading and increased price transparency, want to practice   indexing or active bond trading. However, bond ETFs are suitable for   particular strategies. If, for instance, you are looking to create a   specific income stream, bond ETFs may not be for you. Be sure to   compare your alternatives before investing." Imagine that the existing interest rate is 5%. So on a bond with face value of 100, you would be getting a $5 coupon implying a 5% yield. Now, if let's say the interest rates go up to 10%, then a new bond issued with a face value of 100 will give you a coupon of $10 implying a 10% yield. If someone in the bond market buys your bond after interest price adjustment, in order to make the 10% yield (which means that an investor typically targets at least the risk-free rate on his investments) he needs to buy your bond at $50 so that a $5 coupon can give a 10% yield. The reverse happens when interest rates go down. I hope this somewhat clears the picture. Yield = Coupon/Investment Amount Update: Since the interest rate of the bond does not change after its issuance, the arbitrage in the interest rate is reflected in the market price of the bond. This helps in bringing back the yields of old bonds in-line with the freshly issued bonds. "I made an investing mistake many (eight?) years ago. Specifically, I invested a very large sum of money in a certain triple leveraged ETF (the asset has not yet been sold, but the value has decreased to maybe one 8th or 5th of the original amount). I thought the risk involved was the volatility--I didn't realize that due to the nature of the asset the value would be constantly decreasing towards zero! Anyhow, my question is what to do next?  I would advise you to sell it ASAP. You didn't mention what ETF it is, but chances are you will continue to lose money. The complicating factor is that I have since moved out of the United States and am living abroad (i.e. Japan). I am permanent resident of my host country, I have a steady salary that is paid by a company incorporated in my host country, and pay taxes to the host government. I file a tax return to the U.S. Government each year, but all my income is excluded so I do not pay any taxes. In this way, I do not think that I can write anything off on my U.S. tax return. Also, I have absolutely no idea if I would be able to write off any losses on my Japanese tax return (I've entrusted all the family tax issues to my wife). Would this be possible?  I can't answer this question but you seem to be looking for information on ""cross-border tax harvesting"". If Google doesn't yield useful results, I'd suggest you talk to an accountant who is familiar with the relevant tax codes. Are there any other available options (that would not involve having to tell my wife about the loss, which would be inevitable if I were to go the tax write-off route in Japan)? This is off topic but you should probably have an honest conversation with your wife regardless. If I continue to hold onto this asset the value will decrease lower and lower. Any suggestions as to what to do? See above: close your position ASAP For more information on the pitfalls of leveraged ETFs (FINRA) What happens if I hold longer than one trading day?  While there may be trading and hedging strategies that justify holding these investments longer than a day, buy-and-hold investors with an intermediate or long-term time horizon should carefully consider whether these ETFs are appropriate for their portfolio. As discussed above, because leveraged and inverse ETFs reset each day, their performance can quickly diverge from the performance of the underlying index or benchmark. In other words, it is possible that you could suffer significant losses even if the long-term performance of the index showed a gain." http://finance.yahoo.com/q/hp?s=EDV+Historical+Prices shows this which matches Vanguard: Mar 24, 2014  0.769 Dividend Your download link doesn't specify dates which makes me wonder if it is a cumulative distribution or something else as one can wonder how did you ensure that the URL is specifying to list only the most recent distribution and not something else.

"My knowledge relates to ETFs only. By definition, an ETF's total assets can increase or decrease based upon how many shares are issued or redeemed.  If somebody sells shares back to the ETF provider (rather than somebody else on market) then the underlying assets need to be sold, and vice-versa for purchasing from the ETF provider.  ETFs also allow redemptions too in addition to this. For an ETF, to determine its total assets, you need to you need to analyze the Total Shares on Issue multipled by the Net Asset Value.  ETFs are required to report shares outstanding and NAV on a daily basis. ""Total assets"" is probably more a function of marketing rather than ""demand"" and this is why most funds report on a net-asset-value-per-share basis. Some sites report on ""Net Inflows"" is basically the net change in shares outstanding multiplied by the ETF price. If you want to see this plotted over time you can use a such as: http://www.etf.com/etfanalytics/etf-fund-flows-tool which allows you to see this as a ""net flows"" on a date range basis." "Not a bond holder, but when we get dividends we usually just buy up a benchmark index tracking ETF unless/until we're ready to rebalance our portfolio. Most of the trades in the day are earmarked with the reason ""spending cash"". I'd assume it's similar for bond holders and coupons."
