>Doesn't feel right selling when down 11.92%
Literally makes 0 difference whether you keep it, or sell them rebuy at the same price in you ISA account. The end result is the same, it's just psychological.
>Should I have both the S&P500 sold off and brought in at lower price and just do the Vanguard FTSE All-World as well even with the overlap of companies?
Upto you
People here are obsessed with calling out supposed 'overlap', when at the end of the day, it may well be ones intention
The all world has the S+P500 as part of its components. So long as youre aware of this, the percentage it holds, alongside how much of a separate S+P500 etf you have and the percentage of your portfolio it is and are happy with that, then who cares.
End of the day, holding an all world etf alongside a S+P500 etf is still more diverse than having the S+P500 alone. The important thing is you know this and are happy to be more heavily weighted towards US stocks.
On a side note though, might I suggest looking at SPEX. I personally favour equally weighted etfs over market capitalisation ones. It gives you alot more exposure to the mid caps and not so heavily reliant on the bit tech companies
In a market capitalisation etf, the top 10 companies comprises like 33% of the overall portfolio, which is just insane, seeing as you're investing in 500 companies.
An equally weighted one will have them all broadly at 0.2%.
