Should I invest in both S&P 500 IT sector ETF and Vanguard FTSE All-World, or just All-World?

Hi everyone, I’m looking for some advice on simplifying my ETF portfolio. Currently, I invest monthly in: * **Vanguard FTSE All-World (Acc)** * **iShares S&P 500 Information Technology (Acc)** The S&P 500 IT ETF has clearly outperformed in recent years, which is why I added it. However, I know that **Vanguard FTSE All-World already includes all the big US tech companies**, just at market-cap weights. So my dilemma is: * Does it make sense to **keep investing in both** (intentionally overweighting US tech)? * Or is it more sensible long-term to **stick only with Vanguard FTSE All-World** for simplicity and diversification? I’m investing long term (10–20+ years) and I’m comfortable with volatility, but I also want to avoid unnecessary complexity or overlap. I’d really appreciate hearing how others think about: * Overweighting tech vs market-cap weighting * Core-satellite vs single-ETF strategies * Whether past tech outperformance is a good reason to keep the sector ETF Thanks in advance!
