How to build the riskiest portfolio?

Heyo, I’m pretty new to stocks so not very sure the best way to phrase this.

What do you guys look for when you want to find the riskiest stocks to incorporate, like rather insane profits or insane loss. Like what factors and how do you guy analyze the past data to make these decisions?

I don’t want to have like a risk adjusted return like when looking for sharp ratios and stuff but I just want the maximum return for the highest risk.

Thank you! (This is for project)
