I'm another SWYPX refugee -- got out when the NAV had only dropped 3%, when the NAV was in the $9.60s. Last I saw it was down to $8.20 or so. Not good for something marketed as an alternative to "cash."
I'm wary of waiting to the end of the month. I consider an investment-grade short term bond fund as a LOW volatility asset class which I hold to reduce volatility, not enhance it.
