All of the varieties within a given type of security. For example, subclasses of a stock include mid-cap, small cap, high cap, growth and value stocks, among others. While all securities are most similar to others of the same type, discussing subclasses is useful to describe the differences in expense, risk, expected rate of return, and other factors within a certain type.


Each asset class -- stock, bonds, and cash equivalents, for example -- is made up of a number of different groups of investments called subclasses.

Each member of a subclass shares distinctive qualities with other members of the subclass.

For example, some of the subclasses of the asset class bonds are US Treasury bonds, mortgage-backed agency bonds, corporate bonds, and high-yield bonds.

Similarly, some of the subclasses of stock are large-, medium-, and small-company stock, blue chip stock, growth stock, value stock, and income stock.

Because different subclasses of an asset class perform differently, carry different risks, and may go up and down in value at different times, you may be able to increase your return and offset certain risks by diversifying your portfolio, which means holding individual securities within a variety of subclasses within each asset class.

That discrepancy might be explained by the fact that the populations studied in different series have been variable in size, that the assays utilized to determine the IgG subclass levels have been different and not repeated and that the identification of infectious processes has not followed a uniform procedure.
The overall occurrence of IgG subclass deficiency and of MBL deficiency in this study was probably influenced by the sample size and the age group studied.
