I recently noticed that my usual stock bond allocation jumped seemingly overnight from my usual 50/50 to 57/43 in the Vanguard allocation pie chart. About 40% of my liquid NW is in Wellesley and when I dug into it I realized that Vanguards detailed asset allocation tool shows Wellesley at 49% large cap stocks and 1% mid cap. Their fund info page still shows Wellesley at 38% stocks - within its usual range. Does anybody know if this is really a change in Wellesley allocation philosophy or just an error in Vanguards posting? I'm reluctant to call Vanguard and wait for hours with their usual top notch customer service.
