So here is an updated list...
What is slightly surprising to me (given the wealth of data available online) is that these high-yield ETFs are not so easy to find - there does not seem to be a comprehensive list that is ranked by yield. Topyields is one of the more useful sites for identifying high-yielders, including some ETFs - but it does not have a page specifically for the London market ETFs (and you should be aware that you may need to double-check some of the numbers that appear).
Even finding the yields from the ETF providers can be difficult, so I tend to rely on the data provided by Bloomberg or The FT. Having said that, you obviously need to know what ETF to look for - and therein lies the challenge.
So I've had to do it myself - but ETFs come in all shapes and sizes. For this post I have reviewed all my previous ETF suggestions and trawled through the list of ETFs quoted on the London Stock Exchange (LSE) published by The Financial Times and Morningstar, which seems to be comprehensive.
Sometimes there is a choice in the currency that the ETF is quoted in - I usually buy the Sterling (GBP or GBX=pence) one but you might want to diversify your currencies. All the ETFs follow a specific index and most are based on physical holdings (some are more 'synthetic'. using tools like 'swaps'). I have not included 'accumulation' ETFs, which roll up the income, as I see the portfolio income as an important mechanism for rejuvenating the portfolio itself.
I think that is quite an interesting collection and it might provide the basis for a well-diversified portfolio for the longer term. My own strategy is to buy the ETFs with the highest yields (within reason) and I like to keep a balance between high-yield dividend shares and high-yield bonds (or other fixed-income). Many experienced investors might see this as rather naïve - but it seems to have worked for me over the last few years...
But do make your own assessment.
To help you on your way (assuming you are interested in this corner of the investment world) here is an updated list of high-yield dividend and fixed-income ETFs I have come across recently. I can't claim that it is comprehensive, so do let me know if I've missed any of your favourites. Currency is Sterling (GBP or GBX) unless shown otherwise (some ETFs have alternative currency versions). Current yields from the FT or Bloomberg are shown. (Note: Yields are as at the date of publication - they will change!)
