Looking at the historical graph, the steady-growth era is behind us. I feel nowadays the only way a fund could rise 100% is after a crash. Can we go in after the crash? Well most investors (myself included) is simply unable to time the market so well. Therefore my answer to the opening question is

None

Take-away: So I’d say be realistic and don’t try to be a god on the market.

Individual stocks could, but they are off limits.
