Is just investing in ftse 100 and s&p 500 a good investment
Arguably, you don’t need the Ftse 100 and the S&P500 or a global tracker will do.
The Ftse 100’s a relatively poor representation of the UK market as many of the companies are global, so most of their revenue come from overseas.
Do you have a reason for excluding the rest of the global market? If not a global ETF might be a good option, but do your own research and understand your personal risk tolerance. A global ETF will contain over 60% US stocks anyway and you could always increase your FTSE 100 allocation buying a FTSE100 ETF or individual stocks if you feel confident enough to make these choices.
Agree with all the above.
Also agree that the FTSE 100 and S&P500 are good investments.
Its your choice about exposure, risk and most importantly what you are happy with.
Research your options, and if thats what you decide on then I think thats a perfectly good investment choice and will do better than most.
Just understand your options first
Just to add: if you are minded to go with the Ftse 100 or any other UK index, remember the country makes up about 4-5% of global markets.
Some people like to overweight their own country and it’s fine do so but you don’t want to go overboard.
As a guide, I think Vanguard’s life strategy funds have about 20% in the UK.
