You could always buy a ultra-short-term bond ETF within the account if you're planning to float a non-negligible amount of cash.

  That was going to be my next question: what kind of fund should the "cash" go into?
  • thedufer 7y ago
    Money market funds would likely be appropriate (I believe Vanguard actually does this for you, rather than keeping cash lying around).
    • icedchai 7y ago
      They do. Though note that VMMXX (Vanguard Prime Money Market) pays a bit more than VMFXX (Vanguard Federal Money Market.) VMFXX / Federal is their default settlement fund, so if you have large cash holdings it is still advantageous to put it into alternate funds.

        Unrelated question: VMMXX has a higher yield (2.35% currently) compared to VMFXX (2.29%) but also has a higher expense ratio (0.16% vs 0.11%). Do these cancel each other out?
        • icedchai 7y ago
          No, the yields are net of expenses so VMMXX is still slightly higher performing.
