Frequently Asked Questions

Why should every married woman over 40 have a high-yield account in her own individual name?

Joint accounts can be drained or frozen during a dispute. Holding at least 3 months of expenses in an individual account in your own name guarantees you always have independent mobility and legal retainer access.

Does SGOV fluctuate like the stock market?

No—SGOV holds ultra-short 0-to-3 month US Treasury bills; its price simply accrues a few cents of interest each week and pays it out as a dividend on the 1st of every month.
