It is now becoming sadder by the day that TIAA-CREF is my only choice for my pension and 403(b) plans. I have them for the past 2 years and in that time they have increased the expense rations on their index funds, levered up their RE account just before the real estate crash, and now they are taking away my SCV fund choice. I just received a letter that they are merging all SCV accounts into the SCB fund to "simplify" things. So all of my SCV holdings will be moved on June 2nd into SCB. I do not recall Fama/French using SCB in their analysis, and this is a major disruption to my AA not to have SCV available for my pension account or 403b.
To maintain my AA, I will essentially have to completely reconfigure my IRA accounts, and revisit my future plan since I will not have SCV (and never had EM) available at TIAA-CREF.
