What percentage of individual stocks in your portfolio for moonshots?

Happy New Year everyone.

Starting year two of my Roth with the max​​​​imum contribution, and I want to start adding some individual stocks for hopefully high long term ​gains.

As such, what percentage is a reasonable allocation? I'm looking to add 6 or so stocks and leave the rest for in​​dex funds.

Looking at LUNR, ASTS​, POET, RKLB, ACMR, LAES.

Also, I want to allocate some to HOOW to DRIP one week, then fund something else, then redrip, etc. What percentage makes reasonable sense with that in mind?

Thanks.​​​​
