Thank you for adding your thoughts to the discussion .
As to your suggestion re VFINX vs. PRWCX, setting aside the small matter that the latter has been closed to new investors for several years already, I respectfully disagree.
While the two funds have very similar 15-year results (PRWCX is only 0.04%/year ahead as of today), PRWCX’s 10-year standard deviation (Morningstar doesn’t provide a 15-year SD), at 9.37, is 31% lower than VFINX’s 13.63.
Thus, the conservative investor should want the fund that slightly edged out the index fund while taking significantly less risk.
