Columnist Chuck Jaffe writes on The San Francisco Chronicle's SFGate.com, "Comparing money market funds, online savings". He says, "With Treasury yields at ultra-low levels, many money market fund investors are wondering whether they need to move up the risk scale, moving their cash into prime money market funds or other investment vehicles to squeak out just a bit more yield. For savers or investors hoarding cash, the real question should not be whether to invest in a higher-yielding money fund; it should be whether to leave funds altogether for the better returns available in ordinary savings accounts, particularly high-yield online bank accounts." Jaffe finishes, "After yield and protection concerns, the decision boils down to convenience, habits and account rules."
