Some strategies only work with small investment sizes or require a lot of effort, so don't scale well. Big firms leave tons of (for them) small opportunities on the table, because it's not worth their time. Similarly, there are people who can regularly beat the market that don't have much to offer large funds because their methods don't scale.
