Down at the bottom of the list at #45 & #46 are VOO & SPY with VOO leading by $40K(0.26%)out of $15M.

My guess is this is Warren's benchmark that he keeps in the portfolio as a performance measure for all others & I believe VOO is his favorite of the two.
Maybe someone knows how long these have been there and if I am right in assuming equal amounts were purchased at the same time.
