And for investors who want to position their portfolios in an ever-changing marketplace, how should they think about focusing in on growth or values in terms of Russell ETFs to help express those views?

Yeah, when thinking about growth and value exposures using, in this case, Russell Indices, it's really about bringing a bit more control into the portfolio.

I would say the starting point is the methodology, and Russell uses a transparent rule-based framework to define growth and value so investors have a clear and consistent understanding of what they own.

Growth and value, as we know, tend to perform differently across market environments.

So investors can kill to world value if they want a more valuation sensitive exposure or to world growth if they are looking for companies with a stronger earnings potential, for example.

Over time, we know that market performance can shift a portfolio's style exposure unintentionally.

For example, strong growth performance can increase the allocation beyond what was originally intended.

What about when investors want to think about market cap? How should they think about the Russell 2000 and its ability to diversify their portfolio?
