With regards to your remark "That’s why I am both pleased with the overall survey results and disappointed by the 5% figure. Multi-asset investing is about pulling all the levers and adding value in any way we can. So the future star of the investment profession is not an asset allocator or a stock picker. The successful investor will be the one who who [sic] can do both well."
Keep in mind that we were given discrete choices when voting. It's not necessarily to say that stock selection isn't value additive, but perhaps not considered the "most" value additive amongst those options. No need to be disappointed.
