Exam 13: Empirical Evidence on Security Returns
When portfolio performance is measured, what type of benchmark may be used
Explain what Roll meant by benchmark error.
The benchmark portfolio should be broadly based since it is a proxy for the unobservable market portfolio.Examples include, but are not limited to, the S&P 500 Index, the NYSE Composite Index, and the Wilshire 5000 Index.
Benchmark error refers to the fact that the proxy for the market portfolio may not be mean-variance efficient when the True market portfolio is not efficient.The proxy index may also be inefficient.Also, different proxies may lead to substantially different conclusions even though they tend to be highly correlated with each other.
Feedback: This question tests whether the student understands some of the difficulties that are encountered when trying to apply the CAPM, especially the ideas of expected returns versus actual returns and finding a proxy for the unobservable market portfolio.
The Fama and French three-factor model does not use ___ as one of the explanatory factors.
E
In the 1972 empirical study by Black, Jensen, and Scholes, they found that the risk-adjusted returns of high beta portfolios were _____________ the risk-adjusted returns of low beta portfolios.
C
Fama and French (2002) studied the equity premium puzzle by breaking their sample into subperiods and found that
Kandel and Stambaugh (1995) expanded Roll's critique of the CAPM by arguing that tests rejecting a positive relationship between average return and beta are demonstrating
In the results of the earliest estimations of the security market line by Lintner (1965) and Scholes (1972), it was found that the average difference between a stock's return and the risk-free rate was ________ to its beta.
Equity premium puzzle studies may be subject to survivorship bias because
In the 1972 empirical study by Black, Jensen, and Scholes, they found that the estimated slope of the security market line was _______ what the CAPM would predict.
According to Roll, the only testable hypothesis associated with the CAPM is
One way that Black, Jensen and Scholes overcame the problem of measurement error was to
Consider the regression equation: ri - rf = g0 + g1bi + g2s2(ei) + eit
where:
Ri - rt = the average difference between the monthly return on stock i and the monthly risk-free rate
Bi = the beta of stock i
S2(ei) = a measure of the nonsystematic variance of the stock i
If you estimated this regression equation and the CAPM was valid, you would expect the estimated coefficient, g1, to be
An extension of the Fama-French three-factor model was introduced by
Fama and MacBeth (1973) found that the relationship between average excess returns and betas was
Discuss the results of the studies of John Lintner (1965) and Merton Miller and Myron Scholes (1972) in terms of the validity of the capital asset pricing model (CAPM).
Which of the following would be required for tests of the multifactor CAPM and APT
In the empirical study of a multifactor model by Chen, Roll, and Ross, a factor (the factors) that appeared to have significant explanatory power in explaining security returns was (were)
