Is it still wort it to NOW start investing in semiconductors single stock or ETFs as I see a lot of them reached all time high?

Hi, I am currently investing 100€ every month in the iShares s&p500 etf and I treat it as a “retirement fund”. I want to create a separate investing portfolio with more aggressive strategy where to invest 200-300€ a month for a shorter time period (around 5-8 years).
Any recommendations on a specific etf/stock or overall a specific sector/s?
