Cutoff Percentages for Investable Assets Relative to Return Objectives

The CFA exam often asks for two factors that increase and two factors that decrease an individual’s risk tolerance.

The guideline answers often cite that Investable Assets are large/small relative to the return objectives, and this is a factor that increases/decreases risk.

Have you seen guidance suggesting cutoff percentages? Some people suggest <5% for small, 5-10% for moderate and >10% for large, but I wanted to see what y’all thought.

Much obliged.
