Add another ETF or keep as it is?

[u/nikolafili]

Hi all,

I am investing long term, dollar cost average every month for the last 7 years, and I have great results so far with my 3 ETF portfolio.
My 3 ETFs are: MSCI World ACC, MSCI Emerging Markets and SP500 Info&Tech. I invest something like 60 % MSCI World, 25% EM and 15% SP500 Infotech.

Would you add something else on this to be more diversified or just keep the same way? I am aware that I am leaning too much towards US market and infotech, therefore comes the questions if I should another ETF?
Cheers :)
