VAA (Vigilant Asset Allocation) Tactical Asset Allocation Strategy

Vigilant Asset Allocation (VAA) is a breadth-momentum tactical strategy by Keller & Keuning. It monitors the 13612W weighted momentum of all offensive assets as a breadth indicator. When every offensive asset has positive momentum, the portfolio goes fully offensive into the top-ranked asset(s). If even one offensive asset turns negative (breadth parameter B=1), the entire portfolio switches to the best-performing defensive asset. This binary risk-on/risk-off mechanism makes VAA one of the most aggressive crash-protection strategies in the Keller family.
