: Empirical analysis on analyst recommendation persistence from academic research [2][3]

BofA’s recommendation system has obvious hierarchical differences, with distinct performance characteristics for different types:

• Initial Alpha

Financials	+2-3%	9/10	Medium-Low	Stable performance, best persistence, suitable for mid-term holding
