Yk. Choi, THE SENSITIVITY IN TESTS OF THE EFFICIENCY OF A PORTFOLIO AND PORTFOLIO PERFORMANCE-MEASUREMENT, The Quarterly review of economics and finance, 35(2), 1995, pp. 187-206
A theoretical rationale and empirical evidence for the sensitivity of
the test of the efficiency of a given portfolio (or the test of the CA
PM if appropriately designed) are provided. Stock and bond data are em
ployed as the 'left hand side' assets to show that a misspecification
in the 'left-hand-side' (or LHS) assets may cause the sensitivity in t
esting the efficiency of a given portfolio and the measurement in port
folio performance. Also, the results support the use of an 'asset clas
s factor model' in measuring portfolio performance.
