Thanks for the thoughts so far. I do like JustETF.com too, though my “workflow” is often discover a stock I’m interested in, if it’s too pricey per share (I’m using my ISA so no fractions allowed) then I try to find a relevant ETF holding that stock. If I search ETFChannel or JustETF for a specific stock it gies me a list of all ETFs holding it.
What I can’t seem to do is use the ETF screener, filter to London listings and then search for ETFs containing a stock.
However what I hadn’t seen previously is that on JustETF I can search for a stock, go to the ETF tab and then there is an open text field search and I can filter down to those that have UCITS in the name, e.g. https://www.justetf.com/en/stock-profiles/US58155Q1031#etfs - this might do most of what I want. The good thing about ETFChannel is you can search for multiple stocks and it will give you every combination of all/some of those stocks and the proportion of each holding, but I’ve found it only returns the ETF tickers so I can’t search for UCITS in the name
