Down the Style ETFs

Investors who use index-linked exchange-traded funds to slice
and dice various parts of the U.S. market can choose from benchmarks
from Russell, S&P/Barra, and Dow Jones. Since each index family
is governed by its own unique set of rules, they can at times
perform differently, especially in volatile markets.
"Sometimes you'll see significant divergence in style indices,
especially those from S&P/Barra and Russell," said Brad
Pope, head of index strategy and research at Barclays Global Investors.
"A lot of this has to do with reconstitution methodology.
Russell reconstitutes its growth and value indices once a year;
S&P/Barra does it twice. Let's say there's some major market
movement between June and December. When the S&P/Barra indexes
reconstitute, they may have a whole different set of stocks than
Russell does in the style indices. This has happened periodically
in the past."
BGI manages iShares based on the Russell and S&P/Barra indexes,
while State Street Global Advisors offers four ETFs tied to the
Dow Jones Style indexes.

The index providers also have different methodologies for determining
if a stock belongs in the growth or style index.

Stocks not clearly growth or value
(neutral) are ommitted from style indexes. |
Stocks may be in both growth and value
indexes. |
Each company is assigned to either
the value or growth index. |
"There is something to be said for more than one [style]
factor," said Pope. "Each index provider has progressed
a little further along in terms of adding factors. The S&P/Barra
indices use a single factor [p/b], and a company is 100% forced
into one [style or growth] index. On the other hand, Russell uses
an additional factor [long-term earnings growth], while stocks
can be in both the growth and value indices."
Dow Jones has gone a step further by adding more style factors
- six in all. Dow Jones has also created a 'neutral' category
for stocks that are not clearly growth or value. Neutral stocks
are withheld from the growth and value indexes, which results
in more concentrated indexes by definition.
Index providers are slowly moving away from an absolute boundary
or "line in the sand" between indexes to cut down on
excessive turnover. For example, Vanguard is transitioning many
of its U.S. index funds to new benchmarks maintained by Morgan
Stanley Capital International (MSCI) that use "buffer zones"
to curb turnover. Vanguard will likely introduce new ETFs based
on the MSCI style indexes, so investors may soon have even more
options.
"Forced ranking or drawing a line can create index turnover
that may not necessarily be productive," said BGI's Pope.
"For example, a few years ago, tech companies in the [small-cap]
Russell 2000 were growing at a tremendous rate and moving into
the [large-cap] Russell 1000 index. As a result, many companies
were pushed down into the Russell 2000. A year and half later,
the exact opposite happened [when tech crashed]. The bottom line
is that many companies moved into and out of an index when their
market capitalization didn't vary much, rather the market had
moved around them."
