But this is well before

businesses like BlackRock or Vanguard existed.

And so David, with John's supervision, developed the first index funds.

But those ideas were drawn from Gene Farmer's science, his work around efficient markets.

The idea that markets are constantly pricing securities in such a competitive manner, it's very difficult to outguess.

to know in advance what a share price will do given all of those competitive participants buying and selling securities literally by the second.

That was sort of the founding before Dimensional of those ideas or the transfer of those ideas from the science and the halls of academia into real world.

I mean, there's the strategies that encapsulate dimensional because just run us through some of those.

In those early days when you were running that kind of the micro role, tell me what were the attributes that you were seeking in advisors and advisory firms that have now been emulated across the wider group of advisors you now nurture?

Yeah, if you don't mind, can I give a little sort of backstory and context because I'm not sure if all folks listening may be aware of this, but I mean, the business that I work for Dimensional has been a institutional asset manager from its outset in 1981.

And, you know, it was a period about 10 years in where the organization started working with advice professionals around the world.

And there was a fellow that was very influential in that.

sort of transition at Dimensional.

His name was Dan Wheeler.

Amazing.

All good things come in time, right? So thinking to the future, what's the next level of innovation that you think is going to come to the fore?
