27M, starting to invest for the next 20-25 years. Thinking of NBIS and RKLB.

Recently got interested in investing and realised how much I have missed out on gains. I am turning 28 years old in the next few months, based in Europe and currently am in a situation for the next 2 years where I can invest around $1100-1500 per month using IBKR. I’ve already set up an emergency fund and saved up for an apartment. Low-risk investing is covered by my pension funds etc. so I am thinking of using the next 2 years as my most aggressive/risky years but also keeping in mind that the only individual stocks I’d pick would be stocks that I’d hold for at least 2 years and possibly even 20-25 years.

I’ll be investing for the next 20-25 years or more and the approach I am currently thinking of consists of just the S&P500 and I am also thinking of putting around $1000 into both RKLB and NBIS and just let that sit for a while and see where it goes.

I’m sitting on around $5000 to deploy immediately. What I am thinking is wait for a small dip in RKLB or NBIS and invest $1000 each and the rest to S&P500. After the initial lump sum the monthly amount of $1100-1500 all into S&P500 for the next 2 years.

After the 2 years I’ll probably stop contributing to S&P500 and just let that sit for the remainder of the time (18 – 23 years) and start contributing to VWCE for those 18-23 years. 

What do you think? Any advice/thoughts appreciated. Feel free to start a discussion around any individual stock picks you’re thinking of today, especially any that you plan to hold for a long time.
