RT Journal Article SR Electronic T1 An Asset Allocation Debate JF The Journal of Investing FD Institutional Investor Journals SP 9 OP 15 DO 10.3905/joi.2000.319393 VO 9 IS 1 A1 Harold Evensky A1 William W Jahnke A1 Ronald J Surz YR 2000 UL https://pm-research.com/content/9/1/9.abstract AB It has been typically said - at least for some fourteen years - that 94% of a portfolio's total return is attributable to its average allocation to stocks, bonds, and cash.
