A. The key to this question is the relationship between
margins and turns in the ROE portion of ratio models
and formulas.
ROE
= NI/E = Sales/E * NI/Sales
Or
in other words,
ROE
= Margins * Equity Turns
In
the case of this example, assume AD and DS both have
a ROE of 12%. From the model:
AD
= .24 * .5 = .12 ("Half a turn")
DS
= .01 * 12 = .12 ("12 turns")
In
other words when generating ROE:
higher margins times lower turns = lower margins times
higher turns
(Don't confuse, but relate, turns with returns).
