What’s in Your Index: Value vs. Growth
On top of the broad market rout, the divergence between value and growth was too large for investors to ignore.
- The Russell 1000® Value Index fell -13.5% compared to -22.2% for the Russell 1000® Growth Index, resulting in a gap of 8.7%.
- The Russell 2000® Value Index fell -16.1% compared to -20.1% for the Russell 2000® Growth Index, resulting in a gap of 3.9%.2
- Fund flows also favored value over growth in the first half of 2022. Value ETFs added more than $57 billion in net assets compared to $7 billion into growth ETFs, the largest differential on record.3
The value index’s underweight and the growth index’s overweight to size was the second highest contributor, positively to the former and negatively to the latter. The results confirm the notion from a previous article, Index Portfolios Analysis: Looking Through a Factor Lens, which shows that long-only indices inherently have exposures to multiple factors. Here we further demonstrate that the factor describing the index name may not always be the top contributor of return or risk.

When investors think of styles or factors, what often comes to mind are securities that embody these properties. But as company fundamentals and security valuations change, so do their factor profiles, memberships and weights in indices. In the following, we use the annual Russell index reconstitution in June to highlight some notable changes:
- The largest addition to the Russell 1000® Value Index by both size and weight was Meta, which shifted from 100% growth to 79% value.
- The largest company leaving the Russell 1000® Value Index by size was Costco Wholesale, shifting from 7% value to 100% growth.5

(6–12 months). Nonetheless, it is important to keep abreast of portfolio holdings within each index, as well as to understand what factors the portfolios are exposed to and how factors contribute to risk and return.

4 Active factor exposure is the average units of standard deviation relative to the benchmark. Active risk is the average predicted tracking error using Axioma US4 medium horizon fundamental risk model.
5 FTSE Russell uses book-to-price as value, and I/B/E/S forecast medium-term growth (2-year) and sales per share historical growth (5-year) as growth. Stocks are ranked by their value and growth scores, which are converted to standardized units. The standardized units are combined to produce a composite value score (CVS). A probability algorithm is then applied to the CVS distribution to assign growth and value weights to each stock. Stocks are fully represented by the combination of their growth and value weights.
(PB) Price-to-Book Ratio: Companies use the price-to-book ratio (P/B ratio) to compare a firm's market capitalization to its book value. It's calculated by dividing the company's stock price per share by its book value per share (BVPS). An asset's book value is equal to its carrying value on the balance sheet, and companies calculate it by netting the asset against its accumulated depreciation.
