TheStreet.com Rates 37 New ETFs

TheStreet.com Ratings initiated coverage of 37 exchange-traded funds that accrued a sufficient track record of risk and performance data by the end of April 2008.

Two of the funds that opened for business as recently as April of 2007 received our top rating level of Excellent. Both of these are Vanguard exchange-traded funds invested in fixed income securities.

The combination of good grades on both risk and reward resulted in A ratings for the Vanguard Intermediate Term Bond ETF(BIV Quote) and the Vanguard Short Term Bond ETF(BSV Quote).

For these Vanguard funds, the intermediate term refers to U.S. government debt and investment grade corporate debt for American and foreign issuers in the five to 10 year maturity range. The short-term variant is limited to just one to five year maturities. Both funds track corresponding Lehman Brothers Government/Credit indices.

Of the 10 funds where coverage was initiated at the Hold level, the SPDR S&P China ETF(GXC Quote) stands out, with a one-year total return of 46.19%. Excessive volatility neutralized this impressive return, leading to the C rating.

New coverage in the Sell range includes the wide variety of HealthShares that I first wrote about back in March 2007.

With an initial rating of E, investors in the HealthShares Ophthalmology ETF(HHZ Quote) are seeing red after losing 40.20% in a year. Over the same period, the holdings providing the worst of the damage include ISTA Pharmaceuticals Inc(ISTA Quote), off 77.25%; LCA-Vision Inc(LCAV Quote), off 75.12%; TLC Vision Corp(TLCV Quote), off 74.70%; and Opko Health Inc(OPK Quote), off 65.21%.

Also, speculators expecting fat returns from the E- rated HealthShares Metabolic-Endocrine Disorders ETF(HHM Quote) ought to be roundly disappointed with a loss of 36.55%. The one-year loss of 89.61% from Nastech Pharmaceutical(NSTK Quote), 82.12% loss in shares of MannKind(MNKD Quote), and 72.18% drop in Altus Pharmaceuticals(ALTU Quote) contributed most to the investor account shrinkage.
