116. In the APT model the idea of riskless arbitrage is to assemble a portfolio that
requires some initial wealth, will bear no risk, and still earn a profit.
requires no initial wealth, will bear no risk, and still earn a profit.
requires no initial wealth, will bear no systematic risk, and still earn a profit.
requires no initial wealth, will bear no unsystematic risk, and still earn a profit.
requires some initial wealth, will bear no systematic risk, and still earn a profit.
117. In one of their empirical tests of the APT, Roll and Ross examined the relationship between a security’s returns and
its own standard deviation. A finding of a statistically significant relationship would indicate that
APT is valid because a security‘s unsystematic component would be eliminated by diversification.
APT is valid because non-diversifiable components should be explained by factor sensitivities.
APT is invalid because a security’s unsystematic component would be eliminated by diversification.
APT is invalid because standard deviation is not an appropriate factor.
None of these are correct.
118. Cho, Elton, and Gruber tested the APT by examining the number of factors in the return generating process and
found that
five factors were required using Roll-Ross procedures.
six factors were present when using historical beta.
fundamental betas indicated a need for three factors.
All of these are correct.
None of these are correct.
