I'm with Vanguard also and as of Sat. morning Jan. 22nd no DCIX, but my TD Ameritrade account has had the DCIX for several days. If it doesn't show up by the close of business Monday I will give them a call.
No, I called yesterday and asked why, and he gave me no timeframe when they would be in my account. In this electronic age there's no excuse for this. Not that I'm going to sell, I just have better things to worry about.
