CTEF variable and its breadth components reported in Chapter 8 (see
Table 9.3). The only statistically significant sector exposure in the CTEF
variable and the R&D quadratic variable portfolio construction process is
the health care sector exposure.
A lambda tilt value of 1 is initially used in producing efficient portfo-
lios. Active returns rise as the average stock size diminishes, a result consis-
tent with the inefficient markets literature summarized in Dimson (1988)
