Even the well balanced US indexed funds are bringing in currently 140-150% return over 5 years.
Which is less than your minimum 15% per annum….
Look back over 10 years (to include the 2008) crash and their performance will be much much worse.
Like I say, list specific funds that have achieved >15% year on year over the last 10 years.
EDIT: Look at the NASDAQ over the last 5 years, any basic tracker would have achieved 200% cumulative growth (15% pa). This isn’t investor skill or great fund management, it’s just riding a rising market. Any fool can do that.

However, look at it over 10 years and you aren’t doing quite so well, you cumulative year on year gain would be roughly half that (7% ish). I’d be impressed to see any major fund achieve 15% pa cumulative over that last 10 years (obviously higher risk, lower volume fund might, but they could just as easily fold as well).
