I’m from EU and currently building a long-term ETF portfolio while also contributing separately to my 2nd (employer) and 3rd (myself) pillar pension fund.

My goal is long-term wealth building (15–25+ years), and I invest monthly using a fixed percentage of my salary.

Right now my portfolio allocation looks like this:

• 32% — iShares Core S&P 500 (SXR8)
• 25% — iShares NASDAQ 100 (EXXT)
• 10% — iShares Core MSCI Emerging Markets (EMIM)
• 9% — iShares Global Aerospace & Defence (DFND)
• 6% — Amundi Prime All Country World (WEBN)
• 6% — WisdomTree Artificial Intelligence (WTAI)
• 6% — VanEck Semiconductor (VVSM)
• 6% — VanEck Space Innovators (JEDI)

A few important notes:

• I already invest separately into a globally diversified pension index fund.
• This portfolio is intentionally more aggressive and tech-heavy.
• I understand there is overlap between SXR8, EXXT, VVSM and WTAI.
• I’m comfortable with volatility and don’t plan to sell during crashes.
• I use the Estonian investment account system, so rebalancing later is tax-efficient.

Mainly looking for opinions on:

• Is the thematic allocation becoming too large?
• Would you simplify anything?
• Is there any obvious concentration risk I’m underestimating?

Not looking for day trading or stock picks — just long-term portfolio feedback.

Thanks!
