Introduction
 Indexes are indicators of the day’s market
activity.
 They help us interpret investment results
and provide a benchmark for performance
measurement.
 They are also useful in financial research
when an investigator seeks to discover the
relationship between certain economic
variables and market results.

Index Construction: Price Weighting


A price-weighted index is composed
of a single share of each of the
index components, regardless of the
price of the share or the size of the
underlying company.



For example, the shares of 30 industrial
companies make up the Dow Jones Industrial
Average (DJIA).



To account for artificial price changes due to
stock splits, an index divisor is made
use of.

Index Construction: Equal Weighting




An equal-weighted index reflects the

performance associated with the
selection of a particular security by
chance. It is measured by price
change rather than by price alone.

Theoretically, equal weighting is preferable to
price weighting.

Index Construction: Capitalization Weighting




In capitalization weighting, also
called value weighting, the share
price is multiplied by the number of

outstanding shares.

The total is then compared to some arbitrary
starting value (base value).

Dow Jones Averages



The four primary averages are the industrial
average (30 large blue chip companies), the
transportation average (20 transportation
companies), the utilities average (15 public
utility stocks), and the Dow Jones composite
(all the 65 stocks in the DJIA, DJTA, and
DJUA).



Standard & Poor’s Indexes


The main indexes are the S&P 500 Composite
(500 NYSE-traded securities), S&P Mid Cap 400
(400 mid-capitalization securities), S&P Small
Cap 600 (600 small-cap stocks), and the S&P
Super Composite 1500 (500 + 400 + 600).



Value-weighted.



Note that a divisor is still necessary because of
firm replacements, issuance of additional
shares, and share repurchases.

The NYSE Composite is an average of all the
stocks listed on the New York Stock Exchange.



The Russell 3000 index is a mixture of both
large- and small-capitalization stocks and, to
many portfolio managers, a better
representation of the broad market.
