I have both of them in my portfolio and they are essentially the same. One is an ETF and the other is a mutual fund but each has the same holdings. Though they never finish the day exactly the same the difference today makes no sense. VUG up just 1.37% while VIGAX is up nearly 2 times that at 2.42%??? Does anyone know the reason behind this today? The dividend is not until the end of next month.
