Help me reverse-engineering this strategy!

Greetings!

So I am from Europe and my friend is playing with me this prank that he knows some real investment strategy with awesome-sounding parameters and he is the only one knowing it around here but don’t tell me more.

But I am curious so let’s find out what is he all about!

Here is what we know so far:

  • Forbes called it the US’s best kept investment secret - though I tried to search for it with these keywords but to no avail
  • 50% expected return per year on average
  • 1 in 10 case the profit is more like 300-400%
  • 100% risk free

If you have identified this strategy just tell me it’s name. Many thanks.

And keep all the money people send you wanting the secrets.
