MORNINGSTAR STYLE BOX
The Morningstar Style BoxT was introduced in 1992 to help investors and advisors determine the investment style of a fund. The equity Style Box is a nine-square grid that classifies securities by size along the vertical axis and by value and growth characteristics along the horizontal axis. Different investment styles often have different levels of risk and lead to differences in returns. Therefore, it is crucial that investors understand style and have a tool to measure their style exposure. For the Fixed-Income Morningstar Style Box, see Fixed-Income Style Box.
Benefits
Morningstar's equity style methodology uses a "building block," holdings-based approach that is consistent with Morningstar's fundamental approach to investing. Style is first determined at the stock level and then those attributes are "rolled up" to determine the overall investment style of a fund or portfolio. This unified framework can link what are often treated as separate processes-stock research, fund research, portfolio assembly, and market monitoring-in the belief that a shared analytical framework will lead to better portfolio construction and fund usage.
Morningstar uses 10 different stock characteristics to measure value and growth, and this produces more accurate and stable stock and portfolio style assignments. Morningstar uses both forward-looking and historical-based components to ensure that information available to active portfolio managers is incorporated in the model. This robust approach to style analysis is a powerful lens for understanding stocks, funds, and portfolios.
The Morningstar Style Box is applicable in all equity markets. A geographic framework ensures that style assignments are relevant to local investors everywhere. As of March 31, 2004, all U.S. and non-U.S. stocks and portfolios are evaluated under the same style methodology. This methodology was originally introduced in May 2002 for U.S. stocks and portfolios only.
Using the Style Box
In general, a growth-oriented portfolio will hold the stocks of companies that the portfolio manager believes will increase factors such as sales and earnings faster than the rest of the market. A value-oriented portfolio contains mostly stocks the manager thinks are currently undervalued in price and will eventually see their worth recognized by the market. A blend portfolio might be a mix of growth stocks and value stocks, or it may contain stocks that exhibit both characteristics.
The Morningstar Style Box helps investors construct diversified, style-controlled portfolios based on the style characteristics of all the stocks and funds included in that portfolio.
Origin
Morningstar generates Style Boxes for stocks and portfolios in-house, using data culled from our internal databases. Style Box assignments for stocks are updated each month. Style Box assignments for portfolios are recalculated whenever Morningstar receives updated holdings for the portfolio.
The Style Box also forms the basis for the style-based Morningstar Categories and market indexes.
For the Pros
The Morningstar Style Box captures three of the major considerations in equity investing: size, security valuation and security growth. Value and growth are measured separately because they are distinct concepts. A stock's value orientation reflects the price that investors are willing to pay for some combination of the stock's anticipated per-share earnings, book value, revenues, cash flow, and dividends. A high price relative to these measures indicates that a stock's value orientation is weak, but it does not necessarily mean that the stock is growth-oriented. Instead, a stock's growth orientation is independent of its price and reflects the growth rates of fundamental variables such as earnings, book value, revenues, and cash flow. When neither value nor growth is dominant, stocks are classified as "core" and portfolios are classified as "blend."
Stock Size Score: Vertical Axis
Rather than using a fixed number of "large cap" or "small cap" stocks, Morningstar uses a flexible system that isn't adversely affected by overall movements in the market. World equity markets are first divided into seven style zones:
United States
Latin America
Canada
Europe
Japan
Asia ex-Japan
Australia/New Zealand
The stocks in each style zone are further subdivided into size groups. Giant-cap stocks are defined as those that account for the top 40% of the capitalization of each style zone; large-cap stocks represent the next 30%; mid-cap stocks represent the next 20%; small-cap stocks represent the next 7% and micro-cap stocks represent the smallest 3%. For value-growth scoring, giant-cap stocks are included with the large-cap group for that style zone, and micro-caps are scored against the small-cap group for that style zone.
Stock Style Score: Horizontal Axis
The scores for a stock's value and growth characteristics determine its horizontal placement. There are five value factors and five growth factors, which are listed below.
Value Score Components and Weights
Forward Looking
Price/Projected Earnings 50.0%
Historical-Based Measures
Price/Book 12.5%
Price/Sales 12.5%
Price/Cash Flow 12.5%
Dividend Yield 12.5%
Growth Score Components and Weights
Forward Looking
Long-term Projected Earnings Growth 50.0%
Historical-Based Measures
Book Value Growth 12.5%
Sales Growth 12.5%
Cash Flow Growth 12.5%
Historical Earnings Growth 12.5%
The five value and five growth characteristics for each individual stock are compared to those of other stocks within the same scoring group (groups based on style zone and size, e.g. Europe large-caps). Stocks are then assigned Overall Value and Overall Growth scores based on the ten factors. If either growth or value is dominant, the stock is classified accordingly. If the scores for value and growth are similar in strength, the stock is classified as "core."
The thresholds between value, core, and growth stocks vary to some degree over time, as the distribution of stock styles changes in each style zone. However, on average, the three stock styles each account for approximately one-third of the total capitalization in each scoring group.
Moving from Individual Stocks to Portfolios
A stock fund or portfolio is an aggregation of individual stocks and its style is determined by the style assignments of the stocks it owns. Style Box assignments for portfolios are based on the asset-weighted average of the style and size scores of the underlying stocks. Few or no portfolios contain only stocks with extreme value-growth orientations, and both value and growth managers often hold core stocks for diversification or other reasons. Therefore, for portfolios, the central column of the Style Box represents the "blend" style (a mixture of growth and value stocks or mostly core stocks).
Fixed-Income Style Box
Domestic and international fixed-income funds focus on the two pillars of fixed-income performance: interest-rate sensitivity and credit quality. Morningstar splits fixed-income funds into three groups of interest rate sensitivity (high, medium, and low) and three credit-quality groups (high, medium, and low). These groupings graphically display a portfolio's average effective duration and credit quality. As with equity funds, nine possible combinations exist, ranging from short maturity/high quality for the safest funds to long maturity/low quality for the more volatile.
Along the horizontal axis of the style box lies the average term length of a fund's bond portfolio based on average effective duration. This figure, which is calculated by the fund companies, weights each bond's duration by its relative size within the portfolio. Duration provides a more accurate description of a bond's true interest-rate sensitivity than does maturity because it takes into consideration all mortgage prepayments, puts, and adjustable coupons. Funds with an average effective maturity of less than 3.5 years qualify as short term. Funds with bonds that have an average effective duration greater than or equal to 3.5 years but less than or equal to six years are categorized as intermediate, and those with maturity that exceeds six years are long term. (The duration ranges vary slightly for municipal-bond funds: Less than 4.5 years is short term; 4.5 to seven years is intermediate; and greater than seven years is long term.)
If duration data are not available, Morningstar will use average effective maturity figures to calculate the fund's style box. Although duration is the more accurate measurement, maturity can also be used to gauge the amount of interest-rate risk in a fund's portfolio. Funds with bonds that have an average effective maturity of less than four years qualify as short term. Funds with an average effective maturity greater than or equal to four years but less than or equal to 10 years are categorized as intermediate, and those with maturity that exceeds 10 years are long term.
Along the vertical axis of a fixed-income style box lies the average quality rating of a bond portfolio. Funds that have an average credit rating of AAA or AA are categorized as high quality. Bond portfolios with average ratings of A or BBB are medium quality, and those rated below BB are categorized as low quality. For the purposes of Morningstar's calculations, U.S. government securities are considered AAA bonds, nonrated municipal bonds generally are classified as BB, and all other nonrated bonds are considered B.
For hybrid funds, both equity and fixed-income style boxes appear.
Portfolio Date (explanation of reporting frequency)
Morningstar makes every effort to gather the most up-to-date portfolio
information from a fund. By law, however, funds need only report this
information two times during a calendar year, and they have two months
after the report date to actually release the shareholder report and portfolio.
Therefore, it's possible that a fund's portfolio could be up to eight
months old at the time of publication. We print the date the portfolio
was reported.
Older portfolios should not be
disregarded, however. Although the data may not represent the exact current
holdings of the fund, it may still provide a good picture of the overall
nature of the fund's management style.
Asset Allocation
% Cash
This data point identifies
the percentage of the fund's net assets held in cash. Cash encompasses
both actual cash and cash equivalents (fixed-income securities with
a maturity of one year or less) held by the portfolio plus receivables
minus payables. Negative percentages of cash indicate that the portfolio
is leveraged, meaning it has borrowed against its own assets to buy
more securities or that it has used other techniques to gain more than
100% exposure to the market.
% Stocks
The percentage listed under the heading Stocks incorporates only the
portfolio's straight common stock holdings.
% Bonds
This data point identifies the percentage of the fund's net assets held
in bonds. Bonds include everything from government notes to high-yield
corporate bonds.
% Other
Other includes preferred stocks (equity securities that pay dividends
at a specific rate) as well as convertible bonds and convertible preferreds,
which are corporate securities that are exchangeable for a set amount
of another form of security (usually common shares) at a prestated price.
Other also may denote holdings in not-so-neatly-categorized securities,
such as warrants and options.
Turnover Ratio
This is a measure of the fund's trading activity which is computed by taking the
lesser of purchases or sales (excluding all securities with maturities of less than
one year) and dividing by average monthly net assets. A turnover ratio of 100% or
more does not necessarily suggest that all securities in the portfolio have been
traded. In practical terms, the resulting percentage loosely represents the
percentage of the portfolio's holdings that have changed over the past year.
Benefits: A low turnover figure (20% to 30%) would indicate a buy-and-hold
strategy. High turnover (more than 100%) would indicate an investment strategy
involving considerable buying and selling of securities. Origin: Morningstar does
not calculate turnover ratios. The figure is culled directly from the financial
highlights of the fund's annual report.
% Assets in Top 10
The aggregate assets, expressed as a percentage, of the fund's top 10 portfolio
holdings. This figure is meant to be a measure of portfolio risk. Specifically,
the higher the percentage, the more concentrated the fund is in a few companies or
issues, and the more the fund is susceptible to the market fluctuations in these
few holdings. The figure is calculated from the most recent available fund
holdings. Benefits: The Percent Assets in Top 10 Holdings figure provides insight
into the degree to which a portfolio is diversified. Used in combination with the
total number of holdings, it can indicate how concentrated a fund is. Origin:
This figure is calculated in-house, using the most recent portfolio we have
available for the fund. It currently counts cash as a holding.

Top 3 Credit Weightings
For corporate-bond and municipal-bond funds, the credit weightings depict
the quality of bonds in the fund's portfolio. The weightings reveal the
percentage of fixed-income securities that fall within each credit-quality
rating as assigned by Standard & Poor's or Moody's. At the top of
the ratings are U.S. government bonds. Bonds issued and backed by the
federal government are of extremely high quality and thus are considered
superior to bonds rated AAA, which is the highest possible rating a corporate
issue can receive. Morningstar gives U.S. government bonds a credit rating
separate from AAA securities to allow for a more accurate credit analysis
of a portfolio's holdings. Bonds with a BBB rating are the lowest bonds
that are still considered to be of investment-grade. Bonds that are rated
BB or lower (often called junk bonds or high-yield bonds) are considered
to be quite speculative. Any bonds that appear in the Not Rated or Not
Available category are either not rated by Standard & Poor's or Moody's,
or do not have a rating available at this time.
