Definition 14.1 Research Craft: Predictors, Backtests, Measurement, Portfolios · Chapitre 14 — Signal Combination

Signal combination is the construction of one predictor from several. A composite signal is a weighted sum F=∑kwkzkF = \sum_k w_k z_k of the signals zkz_k, each standardised across names on every date; the equal-weight blend sets every wk=1/Kw_k = 1/K.

Out-of-sample IC of the equal-weight blend of K of the forty planted signals (stable world, last five years), against the proposition with their mean IC 0.015 and mean pairwise correlation 0.027. Data: rs_combine on firm.synthmkt.
