"Money Market ETFs" Not True Money Markets But Enhanced Cash.
TheStreet.com recently wrote "
Money Market ETF Not as Safe as it Appears", describing a new
Powershares VRDO Tax-Free Weekly Portfolio (PVI). The ETF invests in
tax-exempt variable-rate demand notes, a staple of tax-exempt money market funds, and "
seeks to replicate the
Thomson Municipal Money Market Data VRDO Index. TheStreet
incorrectly terms this new exchange traded fund a "Money Market", but PowerShares makes no such claim.
Other ETFs -- iShares Lehman 1-3 Year Treasury Bond, SPDR Lehman 1-3 Mo T-Bill ETF, and the pending Bear Stearns Current Yield Fund -- have bordered on money markets but are really "cash plus" or "enhanced cash". None to-
date offers the liquidity, safety and yield of a true money market fund.
The Powershares launch is ill-timed given concerns in the municipal market over bond insurers, and given concerns over "enhanced cash" funds in general.
