You would be extremely unlikely to find buying prices following that pattern - well, apart from Jan 2020 - May 2020and still be under water in 8 years time
Sure, this was overly simplified to make the figures round. A real work example from an ETF I had of Purchase 1: 36, Purchase 2: 37, Purchase 3: 40, Purchase 4: 42, Purchase 5: 40, Purchase 6: 37, Purchase 7: 34, Purchase 8: 32, Purchase 9, 30 and the current price of 36 is a whole lot more complex to get the point across.
Thanks for this. Based on your logic, the -100 gets treated as nil and the deemed disposal is 300 for tax purposes in year 8. The example was based on 100 units in each purchase to simply things down for the loss relief part.
I've found an old post from 2015 (
https://www.askaboutmoney.com/threa...-year-roll-up-tax-on-efts.194566/post-1435906) which has similar logic which has an except from a mail from the Revenue "If there is a loss in any of the ETFs, it is treated as a Nil gain and you cannot reduce any gains by such a loss."
If this is really the case where someone can't offset losses in ETFs, even in the same ETF across multiple investments, I expect we'll see a lot of very angry people in the coming years as the likes of DeGiro have made ETF investing a whole lot more common with their very low entry point.
Then again given how this is very similar to how Revenue have been treating peer to peer lending and loss relief there, this is very likely the case.
