disclaimer: I did a search for this and couldn't find anything. Sorry in advance if it's been beaten to death.

These questions assume that the stock market is inefficient enough such that a small percentage of investors can beat the overall market average (without assuming risks proportional to their rewards) for a substantial amount.

Over a timeframe of 30 years, what % of investors do you think fall into a group that can beat the market by 2%? 5%? 10%?

More importantly, what traits does this group of investors possess that lets them perceive value better than the rest of the market?

I have some thoughts, but I'd like to hear your thoughts first.
