€10k Portfolio for 5 Years – How Would You Diversify the ETF Portion?

Dear r/investing,

I have €10,000 that I want to invest for 5 years (the time horizon is fixed in my case). I’ve looked into different options and came across the following portfolio structure: 80% ETFs and 20% Xetra-Gold. In Germany, if I hold physical gold for more than one year, there can be tax benefits, so in my case, the 5-year holding period would apply.

For the remaining 80%, I want to invest in ETFs that do not include financial companies, companies involved in betting or alcohol, or fixed-interest investments, as these are against my personal principles.

My initial idea was to invest the remaining 80% as follows:

45% Nasdaq-100 (accumulating)
35% MSCI World Health Care

However, my concern is that both are very industry-focused. The Nasdaq-100 has a heavy concentration in the IT/technology sector, while the MSCI World Health Care is obviously focused entirely on healthcare.

My main goal is to preserve my €10,000 over the 5-year period while ideally earning around 7–8% annually.

What would you recommend for the ETF portion? Would this portfolio make sense for a fixed 5-year horizon, or would you diversify differently?
