OWNERSHIP ZONE
Traditionally, Morningstar has used the equity style box to classify funds
based on their underlying holdings. However, to offer a more complete picture
of how the fund's holdings are distributed, Morningstar has developed ownership zones.
Ownership zones are the shaded areas of the style box intended to be a visual
measure of a fund's style scope--that is, the primary area of a fund's ownership
within the style box. Some key points to remember about the ownership zone are that
it encompasses 75% of the stock holdings in the fund's portfolio, and that it is
centered around a centroid that is determined using an asset-weighted calculation.
The fund's centroid represents the weighted average of all the fund's holdings.
The centroid's position is used to assign a fund to one of the nine style-box-based
fund categories.
Observing where the ownership zone falls within the equity style box is useful
because many funds that appear similar in size and style may actually include quite
different security types. For example, it's expected that a fund holding mainly
large-cap growth stocks would behave differently than one containing both large-and
mid-cap growth stocks, yet both funds might be classified as large-cap growth.
Over a period of time, the shape and location of a fund's ownership zone may vary.
This movement is a good indicator of how consistent a fund's style is.
MORNINGSTAR STYLE BOX
The Morningstar Style Box?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).
1. PRICE/EARNINGS - PROJECTED
Price/projected earnings for a stock is the ratio of the company's most recent month-end share price to the company's estimated earnings per share (EPS) for the current fiscal year. If a third-party estimate for the current year EPS is not available, Morningstar will calculate an internal estimate based on the most recently reported EPS and average historical earnings growth rates. Price/projected earnings is one of the five value factors used to calculate the Morningstar Style Box. For portfolios, this data point is calculated by taking an asset-weighted average of the earnings yields (E/P) of all the stocks in the portfolio and then taking the reciprocal of the result.
Benefits
The P/E ratio relates the price of the stock to the per-share earnings of the company. A high P/E generally indicates that the market will pay more to obtain the company because it has confidence in the company's ability to increase its earnings. Conversely, a low P/E indicates that the market has less confidence that the company's earnings will increase, and therefore will not pay as much for its stock. In most cases high average P/E ratio indicates a manager has paid a premium for stocks that have a high potential for increased earnings. If the average P/E ratio is low, the manager may believe that the stocks have an overlooked or undervalued potential for appreciation.
Origin
Morningstar generates this figure in-house based on stock statistics from our internal equities databases. For stocks, this figure is calculated monthly. For funds and portfolios, Morningstar updates this figure upon receipt of the most-recent portfolio holdings from the asset manager.
2. PRICE/BOOK - PROJECTED
Price/book (projected) for a stock is the ratio of the company's most recent month-end share price to the company's estimated book value per share (BPS) for the current fiscal year. Book value is the total assets of a company, less total liabilities. Morningstar calculates internal estimates for the current year BPS based on the most recently reported BPS and average historical book value growth rates. Price/book (projected) is one of the five value factors used to calculate the Morningstar Style Box. For portfolios, this data point is calculated by taking an asset-weighted average of the book value yields (B/P) of all the stocks in the portfolio and then taking the reciprocal of the result.
Benefits
The price/book ratio can tell investors approximately how much they're paying for a company's tangible assets, based on accounting valuations. Assets are usually valued on a company's books at the historical acquisition cost, less any depreciation. The book value may be different than the current market value for those assets and the stock price may reflect that. Also, book value often excludes intangible assets, such as patents, trademarks, and brand names; therefore, companies with a lot of intangible assets often have larger price/book ratios. Value investors frequently look for companies or portfolios that have low price/book ratios.

3. PRICE/SALES - PROJECTED
Price/sales (projected) for a stock is the ratio of the company's most recent month-end share price to the company's estimated sales per share (SPS) for the current fiscal year. Morningstar calculates internal estimates for the current year SPS based on the most recently reported SPS and average historical sales growth rates. Price/sales (projected) is one of the five value factors used to calculate the Morningstar Style Box. For portfolios, this data point is calculated by taking an asset-weighted average of the sales yields (S/P) of all the stocks in the portfolio and then taking the reciprocal of the result.
Benefits
Price/sales is a valuation measure that indicates how much an investor is paying for a revenue stream. Because revenue measures are less subject to accounting standards than many financial statement figures, this valuation measure is more useful than many others in comparing stocks from different countries. Still, without information about the profit margins of the underlying stocks, this statistic is of limited use. This is less of a problem for specialty portfolios, since margins across specific industries are more consistent.

4. PRICE/CASH FLOW - PROJECTED
Price/cash flow (projected) for a stock is the ratio of the company's most recent month-end share price to the company's estimated cash flow per share (CPS) for the current fiscal year. Cash flow measures the ability of a business to generate cash and it acts as a gauge of liquidity and solvency. Morningstar calculates internal estimates for the current year CPS based on the most recently reported CPS and average historical cash flow growth rates. Price/cash flow (projected) is one of the five value factors used to calculate the Morningstar Style Box. For portfolios, this data point is calculated by taking an asset-weighted average of the cash flow yields (C/P) of all the stocks in the portfolio and then taking the reciprocal of the result.
Benefit
The price/cash flow ratio can tell investors approximately how much they're paying for a dollar of cash flow. Because of differences in accounting standards across the globe, price/earnings ratios are not always reasonable for comparing companies from different countries. Price/Cash Flow attempts to provide a consistent standard of comparison.

5. DIVIDEND YIELD - PROJECTED
Dividend yield (projected) for a stock is the percentage of its stock price that a company is projected to pay out as dividends. It is calculated by dividing estimated annual dividends per share (DPS) for the current fiscal year by the company's most recent month-end stock price. Morningstar calculates internal estimates for the current year DPS based on the most recently reported DPS and average historical dividend growth rates. This is one of the five value factors used to calculate the Morningstar Style Box. For portfolios, this data point is calculated by taking an asset-weighted average of the dividend yields of all the stocks in the portfolio.
Benefit
When companies make a profit, they can either share that profit with shareholders in the form of a dividend, or they can reinvest that money into the business. High dividend yields are often indicative of value stocks. Growth stocks tend to reinvest profits back into the company and therefore have low or no dividends.

6. LONG-TERM PROJECTED EARNINGS GROWTH
The long-term projected earnings growth rate for a stock is the average of the available third-party analysts' estimates for three- to five-year EPS growth. Long-term projected earnings growth is one of the five growth factors used to calculate the Morningstar Style Box. For portfolios, this data point is the share-weighted average of the projected earnings growth estimates for all the stocks in the portfolio. (The share-weighted average is more accurate than an asset-weighted average for this type of calculation.)
Benefits
Investors and institutions trade stocks based on their expectations for how stocks will perform in the future. The long-term projected earnings growth rate summarizes stock analysts' estimates for how quickly a company will grow its earnings per share. This measure helps Morningstar determine how strong the overall growth-orientation is for a stock or portfolio.

7. HISTORICAL EARNINGS GROWTH
The historical earnings growth rate for a stock is a measure of how the stock's earnings per share (EPS) has grown over the last five years. Morningstar uses EPS from continuing operations to calculate this growth rate. Historical earnings growth is one of the five growth factors used to calculate the Morningstar Style Box. For portfolios, this data point is the share-weighted collective earnings growth for all stocks in the current portfolio. (The share-weighted average is more accurate than an asset-weighted average for this type of calculation.)
Benefits
The historical earnings growth rate can tell investors how quickly a company's profits are growing. A company may increase its earnings per share by increasing its sales, decreasing its costs, or reducing the number of shares outstanding in the marketplace. The historical earnings growth rate helps Morningstar determine how strong the overall growth-orientation is for a stock or portfolio.

8. BOOK VALUE GROWTH
The book value growth rate for a stock is a measure of how the stock's book value per share (BVPS) has grown over the last five years. Book value growth is one of the five growth factors used to calculate the Morningstar Style Box. For portfolios, this data point is the share-weighted collective book value growth for all stocks in the current portfolio. (The share-weighted average is more accurate than an asset-weighted average for this type of calculation.)
Benefits
Book value growth tells an investor how quickly a company is building its asset base. A company may increase its book value by buying more assets or decreasing its liabilities. The book value growth rate helps Morningstar determine how strong the overall growth-orientation is for a stock or portfolio.

9. SALES GROWTH
The sales growth rate for a stock is a measure of how the stock's sales per share (SPS) has grown over the last five years. Sales growth is one of the five growth factors used to calculate the Morningstar Style Box. For portfolios, this data point is the share-weighted collective sales growth for all stocks in the current portfolio. (The share-weighted average is more accurate than an asset-weighted average for this type of calculation.)
Benefits
Sales growth tells an investor how quickly a company is increasing its revenues. The sales growth rate helps Morningstar determine how strong the overall growth-orientation is for a stock or portfolio.

10. CASH FLOW GROWTH
The cash flow growth rate for a stock is a measure of how the stock's cash flow per share (CFPS) has grown over the last three to five years. Cash flow growth is one of the five growth factors used to calculate the Morningstar Style Box. For portfolios, this data point is the share-weighted collective cash flow growth for all stocks in the current portfolio. (The share-weighted average is more accurate than an asset-weighted average for this type of calculation.)
Benefits
Cash flow growth tells an investor how quickly a company is generating inflows of cash from operations. The cash flow growth rate helps Morningstar determine how strong the overall growth-orientation is for a stock or portfolio.

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 duration 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 duration 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.
