Which of the following statements is false? rather than relying on the efficiency of a single portfolio (such as the market), multifactor models rely on the weaker condition that an efficient portfolio can be constructed from a collection of well-diversified portfolios or factors. a positive alpha in a single factor model means that the portfolios that implement the trading strategy capture risk that is not captured by the market portfolio. multifactor models have a distinct advantage over single-factor models in that it is much easier to identify a collection of portfolios that captures systematic risk than just a single portfolio. trading strategies based on market capitalization, book-to-market ratios, and momentum have been developed that appear to have zero alphas.
