NEW YORK (

TheStreet

) - Assets have flowed out of money market funds this year, as investors seek higher-yielding securities.

With the seven-day yield on taxable money market funds holding steady at a record low of 0.03%, investors are seeking alternatives in both the exchange-trade fund and mutual-fund spaces.

Falling yields and an increasing appetite for risk have spawned a new generation of ETFs, designed to compete with traditional money market funds.

Bond giant PIMCO recently launched two actively-managed ETF strategies aimed at the money market crowd: the

Enhanced Short Maturity Strategy ETF

(MINT) - Get Report

and the

Intermediate Municipal Bond Strategy ETF

(MUNI) - Get Report

.

In the mutual fund space, municipal bond mutual funds continue to see inflows. Funds like the

Federated Adjustable Rate Securities Fund

(FASSX)

also offer investors current income consistent with minimal volatility -- the strategy sought by most money market fund investors.

Money market-fund alternatives have become increasingly attractive to investors in 2009 as money market fund yields steadily decline. As of mid-November, more than $452 billion had flowed out of money market funds year to date, and much of the money flowing out of them gas gone into municipal bond mutual funds.

The November launch of MUNI signaled a new option for municipal bond investors: an actively managed ETF approach from PIMCO. This fund is designed to offer low volatility exposure similar to money market mutual funds or more traditional municipal bond mutual funds. This ETF targets investors who are looking for tax except income, and features a low expense ratio of 0.35%.

The

Pimco's Enhanced Short Maturity Strategy Fund

(MINT) - Get Report

was also launched in November, and is designed to compete with large money market mutual funds like

Fidelity's Cash Reserves

(FDRXX)

. MUNI seeks to provide investors with greater income and total return potential than money market funds by primarily investing in short duration investment grade debt securities.

MINT looks to gain advantage over FDRXX since it can hold longer-maturity bonds and a broader spectrum of investment-grade fixed-income securities. With an expense ratio of 0.35%, MINT also slightly undercuts the expense ratio of FDRXX, which is 0.39%.

The two Pimco funds, MINT and MUNI, were only launched very recently, so it is difficult to assess whether or not they have been seeing better performance than traditional money market mutual funds. However, for investors who want to get off the sidelines while avoiding volatility, these two ETFs represent a conservative way to possibly earn more than by investing in the money market.

The recent decision by the Federal Open Market Committee to target federal-funds rate near zero, affirmed by the central-bank last month, should continue to keep rates low in the foreseeable future. As frustrated investors flee low yields for higher ground, alternatives like MINT and MUNI should continue to see inflows of assets. Together, MINT and MUNI have attracted nearly $40 million in funds thus far.
