Well, explain it then.
What are the investments to do to make 40% return every year guaranteed?

Cleary you haven't done much research on any investments. Nothing is guaranteed in life unfortunately. I have had safe investments make 20 % ROI PA and some rather risky ones do well over 100% in less than 6 months. If you want something bad enough it can happen. Where there is a will there is a way.

No, I haven't done a ton of investment research, but I know that "rock solid 40% return for 15 years" seems like snake oil.

Maybe you want to share your investments.

My current safe investment has never not made me profit in a single given day in 3 years :) and last year it produced 50% xD And that's the safest investment I currently have.. Every single day it's had a small profit :)

Again, I will reveal some decent decisions in a following post :)

My current riskier investment (Still fairly consistent on lower balances, low being $50K and under) produces on average about 480% per year :)
