e. 10B monthly beta
f. Micro-cap annual beta
g. Micro-cap monthly beta
h. Micro-cap sum beta
i. All of the above
ANSWER: i. All of the above
In the valuation of LEGGO, the analysts decided to use the 10th decile
monthly beta. All of these small stock premiums are the premiums in excess
of CAPM that Ibbotson uses to derive small stock risk premium. Some ana-
lysts will use the 10th decile whereas others will use the micro-cap strata,
which is the 9th and 10th deciles. There are also differences of opinion as to
which small stock premiums should be used based on the type of beta. It could
be monthly betas, annual betas, or sum betas. Monthly and annual betas are
based on the timing of the calculation. Sum betas are sometimes referred to as
lagged betas and reflect the fact that small stock market reactions may lag the
market by a certain amount of time. Some analysts use a micro-cap small
stock risk premium because the average includes more companies. In 1999,
the micro-cap risk premium was 2.6% versus the 4.35% used for the 10th
decile. In the 2001 Yearbook the micro-cap risk premium was also 2.6%. In
the 2001 Yearbook, Ibbotson has segmented its information into deciles 10A
and 10B. The 10B decile risk premium was 8.42%. Although the 10B decile
risk premium is based on smaller companies, it is also based on a lower num-
ber of companies that make up the average. There is currently no clear
requirement for selecting small stock risk premiums, and the controversy con-
tinues about whether to use the 10th decile, micro-cap, or 10B strata, as well
as the type of beta on which the information is based.
EXERCISE 46: A list of risk factors was previously presented for LEGGO
to calculate the specific risk premium. Discuss the different methods for deter-
mining what the actual specific risk premium should be.
ANSWER: In this valuation the analyst made a subjective selection of an
aggregate 4% risk premium. This was based on the analyst’s judgment con-
cerning the additional risk of the previously described items. This is a com-
mon method of selecting specific risk premiums. Other methods that can be
used are some type of numerical system placed on the categories (i.e., -3, -2,
-1, 0, 1, 2, 3). However, this sometimes implies accuracy that may not exist
and may be difficult to defend in a litigation setting. Other analysts use a plus
and minus system to determine the potential amount of specific risk.
EXERCISE 47: Specific company risk premiums can be determined from
Ibbotson data.
