Subject: Re: Schwab: Problem to invest cash
3 or 6 months is too long. Max 30 days fixed. I want to be completely flexible without the risk of having to sell before maturity. That's worth more to me than the last %.

If 3 months is too long for you, you can also buy 30-day T-bills. I bought some a couple of weeks ago. But I've mostly been buying 3-month T-bills through Schwab. It's a great option currently--the yields are higher than Schwab's money market funds and there are no fees, unlike Schwab's MM funds (which have a somewhat surprisingly high expense ratio).
