MarketWatch's Chuck Jaffe writes "Low yielding, high-cost money funds are safe but unsound" in his "Stupid Investment of the Week" columb. It quotes us, "A lot of people who are in cash are more interested in return of principal than return on principal, so they don't care about the yield, and that shows," said Peter Crane of Crane Data, publisher of the Money Fund Intelligence newsletter. "If you are running away from a crashing stock market or a financial crisis, having your buying power eroded by inflation isn't exactly tops on your list of imminent perils," he adds. "Investors tend to underestimate the length of time they remained parked."
